e98f3b03 — Kris Yotam chore: sync local state after restore (push updates, no pull) a month ago

#Lifestyle Engineering: Floor Expenses, Maximum Optionality

Target window: 2026-05-20 through 2029-05-20. Goal: floor recurring expenses to $1,500-$2,500/mo all-in, paired with a $250k gross income target by year three. The thesis is simple: at that ratio, the savings rate dominates the strategy. The math, not the income, is the real lever.

#1. The Economics: Why This Matters

Three honest numbers. Assume $250k gross from year three onward, ~22% effective federal tax (FEIE in play where possible, S-corp election on 1099 income), and 7% real return on invested savings.

#Net worth curve at three expense tiers

Net of federal tax, after FEIE and reasonable retirement shelters, take-home lands at roughly $185k on $250k gross for a non-resident or low-tax-state citizen. Annual surplus = take-home minus living expenses. Compound at 7% real.

Year $1,500/mo ($18k/yr) $3,000/mo ($36k/yr) $6,000/mo ($72k/yr)
2027 (Y1, $60k income, ~$48k take-home) $30k saved $12k saved -$24k (deficit)
2028 (Y2, $130k income, ~$103k take-home) $116k cumulative $80k $25k
2029 (Y3, $250k income, ~$185k take-home) $295k cumulative $232k $138k
2030 $493k $383k $214k
2031 $704k $542k $292k
2032 (5yr from now) $930k $710k $371k

The $1,500/mo tier hits $1M in year six. The $6,000/mo tier needs over a decade to get there with the same income. That spread is the entire point of this document.

Tax planning matters more than expense floor. Moving from a 9% state income tax state to 0% on $250k of income is $22,500/yr, the same as removing $1,875/mo from the spend column. Pair the two and the curve bends faster.

#2. Travel

#Flight booking stack

  • Google Flights (https://www.google.com/flights): baseline, calendar view, price tracking, explore map.
  • ITA Matrix (https://matrix.itasoftware.com): the engine under Google Flights, exposes routing codes, multi-city construction, fare bucket inspection. Power-user tool.
  • Kiwi.com (https://www.kiwi.com): finds combinations no airline alliance will sell you, including separate-ticket itineraries. Kiwi Guarantee is real but pricey.
  • Skiplagged (https://skiplagged.com): hidden-city ticketing. Works, violates airline contracts, only do it one-way with carry-on.
  • Hopper (https://hopper.com): mobile-first prediction. Useful as a second opinion, not as a buyer.
  • Going (formerly Scott's Cheap Flights, https://www.going.com): mistake-fare and deep-discount alerts, $49-$199/yr. One $700 transatlantic round trip pays for the whole subscription.
  • Point.me (https://point.me, $129/yr): the only good award-search tool. Searches partner availability across all major programs.
  • Seats.aero (https://seats.aero, $7-$10/mo): faster, broader award search than point.me for power users.
  • AwardWallet (https://awardwallet.com): tracks miles across all programs.

The AI-era of fare search is shifting fast. Treat search tool quality as something to re-check every six months.

#Frequent-flier alliance: pick one, stack hard

For a US-based traveler, the three alliances roughly map to:

Alliance US anchor Strength Weakness
Star Alliance United MileagePlus Widest network (28 carriers), Lufthansa/ANA/Singapore for premium award space United mileage devaluations frequent
OneWorld American AAdvantage, Alaska Mileage Plan Best for South America (LATAM), Asia via JAL/Cathay, partner with British Airways and Qatar American often has worst award availability
SkyTeam Delta SkyMiles Excellent product (Delta One), partner with Korean/Air France/KLM SkyMiles has no published award chart, dynamic pricing

Recommendation for Kris: OneWorld via Alaska Mileage Plan. Alaska partners with American, Cathay, JAL, Qatar, British Airways, Iberia, and more without being inside American's dynamic-pricing mess. Cathay business to Asia for 50k miles one-way is still a thing. Backup: United MileagePlus for the West Coast departures and the Star Alliance partner sprawl.

Pick one, run all credit card spend through it, and don't dilute across three programs.

#Credit card travel hacking (US citizen, 20s)

The realistic stack for someone with a 750+ FICO and a $60-250k income:

Card Annual fee Signup bonus (typical 2026) Key benefit
Chase Sapphire Preferred $95 60-80k UR Entry-level, 1.25x redemption on travel via portal
Chase Sapphire Reserve $795 100k UR Priority Pass, $300 travel credit, points value
Amex Platinum $695 80-150k MR Centurion lounges, $200 hotel credit, $200 airline credit (gameable)
Amex Gold $325 60-90k MR 4x dining and groceries, $120 Uber credit
Capital One Venture X $395 75k+ miles Priority Pass, $300 Cap One Travel, anniversary 10k miles
Chase Ink Business Preferred $95 90-120k UR Best business card for spend bonus, requires LLC/sole prop
Bilt Mastercard $0 Variable Pays rent in points, no annual fee, transfers to most programs

Realistic extraction: $1,500-$3,000/yr in net value after fees, assuming you rotate signup bonuses every 18-24 months and meet minimum spend organically. The honest time cost is 3-5 hours/month if you optimize, less if you set and forget. Sources: r/churning (https://www.reddit.com/r/churning), Doctor of Credit (https://doctorofcredit.com), Frequent Miler (https://frequentmiler.com).

Critical rule: Chase 5/24. Chase will deny you if you've opened 5+ personal cards in 24 months across any issuer. Open Chase cards first, then Amex, then everything else.

#Baggage philosophy: one bag, no checked

The r/OneBag community (https://www.reddit.com/r/onebag) has converged on a few defensible packs. The point: never check a bag, never wait at carousel, lose nothing, fly any airline, walk from any station, no logistics tax.

Bag Capacity Price Best for
Tom Bihn Synik 30 30L $349 Organization fiends, lifetime build
Goruck GR1 21-26L $325-$395 Minimalists, indestructible, ugly enough to deter theft
Aer Travel Pack 3 Small 28L $279 Best clamshell, sleek for cities
Peak Design Travel 30L 30L $300 Photographers, expandable
Cotopaxi Allpa 35L 35L $200 Budget option, durable

Packing cubes: Eagle Creek Pack-It Specter or Peak Design. Three cubes (tops, bottoms, underwear) ends the daily packing decision. Compression cubes save 30% volume.

Recommended kit: 7 shirts, 3 bottoms, 7 underwear, 7 socks, packable down jacket, packable rain shell, one pair of shoes plus sandals, toiletries in silicone bottles, electronics pouch. That's about 18-22 lbs, fits 26L easily.

#Sleep en route

  • Jet lag protocol: start shifting sleep by 30 min/day three days before flight in the direction of destination. On-flight: sleep on destination clock, not departure clock.
  • Melatonin timing: 0.3-0.5 mg (not the 3-5 mg sold OTC), taken at destination bedtime, every night for the first 4-5 days. Higher doses cause grogginess and don't help phase shifting.
  • Fasting trick: the Argonne anti-jet-lag diet (16h fast, eat breakfast at destination time on arrival) has weak evidence but anecdotally works. Easier: just eat on destination schedule the day you arrive, regardless of hunger.
  • Light exposure: bright light on arrival morning, dim light evening. The single most powerful zeitgeber.

#Long-haul economy survival kit

  • Headphones: Soundcore Q45 ($80) or Soundcore Space Q45, around 90% of the Sony XM5 experience at 20% of the price. AirPods Pro 2 ($249) if iPhone integration matters.
  • Neck pillow: Trtl Pillow ($35), not the inflatable horseshoe garbage.
  • Eye mask: Manta Sleep ($35), velcro adjustable, zero light leak.
  • Compression socks: prevents DVT, available everywhere for $15.
  • Wired backup earbuds: airlines still hand out analog jacks, Bluetooth runs out of battery.

#Pricing tactics

  • App pricing vs in-person: ride-hails (Uber, Grab, Bolt) often cheaper than haggled taxis. Local food delivery apps often cheaper than walking into the restaurant in tourist areas.
  • Bargaining: SE Asia and Latin America markets, yes. Don't bargain in Japan, Korea, or Western Europe; it is rude and pointless.
  • Currency tricks: always pay in local currency, never accept "dynamic currency conversion" at terminals. The vendor's exchange rate is always worse than your card's.

#3. Security

#Physical security

#Country risk
  • OSAC (https://www.osac.gov) publishes Country Security Reports for free, by US embassy and consulate. The single best public-source threat read.
  • US State Department Travel Advisories (https://travel.state.gov): Level 1-4. Level 3-4 means insurance gets expensive and embassies will roll their eyes.
  • Specific 2026 cautions for US passport holders:
    • Russia and Belarus: do not enter. Wrongful detention risk has been state-coded.
    • China (mainland): exit ban risk for anyone with mainland business ties, dual citizenship ambiguity, or social media history. PRC has used exit bans against US citizens repeatedly post-2018.
    • Iran, Venezuela, Myanmar, North Korea: do not enter.
    • Parts of Mexico: state-by-state. CDMX, Yucatan, Oaxaca, Querétaro are fine. Sinaloa, Tamaulipas, Michoacán are not.
    • Haiti, Sudan, Libya, Yemen: don't.
#Hotel / Airbnb hardening

Threat model is opportunistic theft and crime of opportunity, not nation-state surveillance. So:

  • Door wedge alarm: $10 on Amazon, slides under door, screams if forced. Best single item.
  • Peephole cover: $5 sticker, prevents external optics. Most hotel doors leak through the peephole.
  • Portable door lock (Addalock, $25): adds a deadbolt to any inward-opening door.
  • Faraday pouch for phones during sensitive meetings, $20.
#EDC and weapons
  • Knife laws: UK has the strictest, anything locking or over 3 inches is a problem. Japan: blade over 6cm is a crime. Most of Europe: 8cm or under, non-locking, generally OK as a tool.
  • Pepper spray: legal in US (most states), banned in UK, Belgium, Denmark, Hungary, Norway, Poland; legal in some form in Canada (dog-spray loophole), Australia, Germany (animal-defense), Italy (under 20ml).
  • Legal alternatives: tactical pen (Schrade SCPEN3, $15), monkey-fist keychain (most places), striking flashlight (Olight, Fenix).
  • Kubotan or Yawara: cheap, useful, legal almost everywhere as a "key holder."
#Cash strategy
  • Money belt (Eagle Creek RFID, $25) holds passport, emergency $500-$1000 cash, backup card. Never your daily kit.
  • Decoy wallet: cheap bifold with $30-$50 cash and an expired card. Hand this over in a mugging.
  • Customs declaration: $10,000 USD or equivalent into/out of the US must be declared (FinCEN 105). Many countries: €10,000. Penalty for non-declaration: seizure plus criminal liability.
#Travel insurance with extraction
Provider Coverage Annual cost Notes
World Nomads Standard travel + medical $400-$900 https://www.worldnomads.com, decent claims
IMG Patriot Platinum Medical heavy $500-$1200 https://www.imglobal.com
GeoBlue Trekker Medical, Blue Cross network abroad $250-$600 https://www.geobluetravelinsurance.com
Global Rescue Actual extraction, medevac, security evac $660-$1295/yr https://www.globalrescue.com — separate from health insurance, pairs with it
SafetyWing Nomad Health + travel $504/yr ($42/mo, under 40) https://safetywing.com
Genki EU-style, no US coverage €72/mo https://genki.world

Stack: SafetyWing or GeoBlue for routine + Global Rescue for the "get me out of here" case. About $1200/yr combined.

#Embassy registration

STEP program (https://step.state.gov): free, US-only, registers your trip with the nearest embassy. They'll contact you in a crisis (earthquake, coup, mass-casualty event) and your family can reach you through them. Takes 5 minutes per trip. Just do it.

#Digital / opsec

#Threat model: be honest
  • Nation-state: if you're targeted by NSA / FSB / MSS, no consumer tooling saves you. Don't engineer for this unless you actually have a reason to.
  • Corporate / law enforcement: realistic. VPN + encrypted comms + device hygiene defeats most.
  • Script kiddie / hotel WiFi snooping: trivial. HTTPS-everywhere + VPN + no cleartext credentials = done.
  • Border / customs: device search is the realistic threat. Plan for it.
#Travel device hygiene
  • Dedicated travel laptop: refurb ThinkPad X1 Carbon ($400-$700, Lenovo Outlet or eBay) or M1/M2 MacBook Air ($600-$800 refurb). Fresh OS, no sensitive data, no SSH keys to your home infra, no client work. Use Tailscale to reach STARGATE for anything sensitive.
  • Primary kit stays at home / on STARGATE: workstation, archive, keys.
  • Full-disk encryption on: LUKS (Linux), FileVault (Mac). Power off, not sleep, before crossing borders. Cold-boot attacks are real but rare.
  • CBP guidance: https://www.cbp.gov/travel/cbp-search-authority. US citizens cannot be denied entry for refusing to unlock, but can have devices seized for forensic imaging (typically 5-30 days).
  • EFF border guide: https://www.eff.org/wp/digital-privacy-us-border-2017. Old but still the canonical reference.
#Crypto across borders
  • Never carry hot wallet seed phrases in plaintext, on paper, or in any document on your devices.
  • Use a passphrase (BIP39 25th word) so the seed alone is useless without the passphrase you carry mentally.
  • Cold-storage seed split: SLIP-39 or Shamir Secret Sharing across two trusted locations.
  • Hardware wallets in checked luggage are fine because they're useless without the seed.
#VPN strategy
Provider Cost Jurisdiction Notes
Mullvad €5/mo flat Sweden (14-Eyes member, but doesn't log) Account = 16-digit number, no email needed. Best privacy reputation.
ProtonVPN $4-$10/mo Switzerland Excellent, ties to ProtonMail account
iVPN $6/mo Gibraltar Similar privacy posture to Mullvad
Self-hosted WireGuard on STARGATE $0 (you own it) Wherever STARGATE lives Doesn't anonymize you to outside observers, but encrypts the path
Tailscale exit node on STARGATE Free (Tailscale plan) US (your house) Makes you appear US-based, useful for streaming, banking, IRS, brokerage

Sweden being technically 14-Eyes-adjacent doesn't disqualify Mullvad in practice. Mullvad has been audited, has no-logs verified by raids and court orders, and accepts cash by mail. For maximum opsec from a non-14-Eyes provider, iVPN (Gibraltar) is the cleanest.

#Yubikey hygiene
  • Two Yubikeys minimum: one daily, one in a secure location (safe at home base). Add a third for travel kit if budget allows.
  • YubiKey 5C NFC ($55): the right model for most work.
  • Pair to every primary account: GitHub, Google, Cloudflare, Mercury, Schwab, Fidelity, Bitwarden/1Password, Proton, all of them.
  • Backup codes printed and stored separately in case both keys die.
#Communications
  • Signal (https://signal.org): always-on default messenger. Real names use real phone numbers, which leaks metadata. Use Signal usernames (rolled out 2024) for non-trusted contacts.
  • SimpleX (https://simplex.chat): no phone number, no identifier. Higher OPSEC, smaller network.
  • Briar (https://briarproject.org): peer-to-peer, no servers, works offline over Bluetooth/WiFi. For protest, conflict, or full offline.
  • Wire / Threema: secondary options. Threema is paid, Swiss, no phone number.
#Email
  • ProtonMail (https://proton.me): Swiss, end-to-end with other ProtonMail users, custom domain support. Bridge for IMAP integration.
  • Tutanota (https://tutanota.com): German, full E2E, less polished. Important: Germany IS 14-Eyes. For maximum jurisdiction filter, ProtonMail > Tutanota.
  • Self-hosted email: Stalwart (https://stalw.art) or Mailcow on STARGATE. Doable, painful, deliverability headaches.
#Password manager
  • Vaultwarden (https://github.com/dani-garcia/vaultwarden): self-hosted Bitwarden-compatible, runs on STARGATE in a single container. Best free option.
  • Bitwarden Premium ($10/yr): hosted, fine.
  • 1Password Family ($60/yr): the polished option. Travel mode actually removes vaults from devices on demand.
#SIM strategy
  • eSIM first wherever supported. Burner-style eSIMs (Airalo, Holafly) are harder for an opportunistic observer to clone. Physical SIM swapping at a kiosk leaves more trail.
  • Use a "burner" SIM number for hotel WiFi captive portals, not your primary line.

#Health

#International medical insurance
Plan Cost (under 40) Coverage Best for
SafetyWing Nomad $42/mo $250k lifetime, includes home country Nomads on a budget
IMG Global Medical Insurance $80-$150/mo Up to $8M Long-term expats
Cigna Global $200-$400/mo Comprehensive Wants a "real" insurance experience abroad
GeoBlue Xplorer $150-$300/mo Blue Cross-affiliated network worldwide US citizens who want US-style coverage abroad

Most digital-nomad insurance is medical-only and lousy for chronic conditions (excludes pre-existing, low maternity coverage). Read the fine print.

#Vaccinations
  • Yellow fever: required for some African and South American countries, single dose lifelong. Get the ICVP certificate.
  • Typhoid: oral or injection, recommended for SE Asia, Africa, parts of Latin America.
  • Hepatitis A/B: 2-3 doses, lifelong. Just do it.
  • Rabies pre-exposure: 3 doses, $800-$1200 cash. Worth it if going truly rural in Asia, Africa, or for cave biology / animal handling.
  • Japanese encephalitis: rural Asia, monsoon season.
  • Cholera: parts of Africa.
  • CDC Travel page: https://wwwnc.cdc.gov/travel.
#Pharmacies abroad

Most of Mexico, Thailand, Vietnam, Indonesia, Philippines, parts of Eastern Europe sell antibiotics, antifungals, and many other prescription-in-US drugs over the counter. Ethics aside, this is well-documented and used by US expats routinely. Do not self-prescribe broad-spectrum antibiotics; resistance and microbiome damage are real. For chronic-medication refills, prices are 10-30% of US pharmacy retail.

#4. Multi-country Movement

#Schengen 90/180

The single hardest European constraint. You can stay in the Schengen Area a maximum of 90 days within any rolling 180. Once you hit 90, you must leave for 90 before returning. Plan accordingly. UK, Ireland, Albania, North Macedonia, Romania, Bulgaria (some still being absorbed), Georgia, Turkey, Cyprus, Croatia (Schengen as of 2023) are the "step out" options.

#Outside-14-Eyes nomad visas ranked for Kris

Based on the academia.md filter (outside US/UK/CA/AU/NZ/DK/FR/NL/NO/DE/BE/IT/ES/SE):

  1. Georgia (Remotely from Georgia / visa-free 365-day) — best in class. No application required, Tbilisi has 1 Gbps internet widely, 1% small-business tax, cost of living is low, US citizens visa-free.
  2. UAE (Virtual Work Visa) — zero income tax, world-class infrastructure, expensive but ROI on $250k is excellent. Dubai/Abu Dhabi.
  3. Thailand (DTV, 2024) — 5-year multi-entry, $14k savings requirement, Chiang Mai cost of living. Foreign income untaxed if not remitted same year.
  4. Costa Rica (Rentista) — Latin America base, foreign income exempt, $3k/mo income req, 1-year renewable.
  5. Panama (Friendly Nations) — fast permanent residency path, foreign-income exempt, Spanish-speaking, time-zone aligned with US.
  6. Mexico (Temporary Resident) — easy, cheap, time-zone aligned, CDMX has excellent infrastructure.
  7. Colombia (M Visa) — Medellín or Bogotá, cheap, low income requirement.
  8. Argentina (DNV) — Buenos Aires is a European-feel city at half the cost, foreign income exempt for non-residents, currency situation evolving.
  9. Malaysia (DE Rantau) — Penang and KL, non-resident foreign income exempt, English widely spoken.
  10. Indonesia (E33G) — Bali, $60k income req, 5-year visa is excellent.

#Residency by Investment

  • Portugal Golden Visa: post-2023 reforms removed real estate. Fund investment ~€500k, business creation, cultural-heritage donation. Still works, leads to citizenship in 5 years with minimal physical presence. Not outside 14-Eyes.
  • Panama Friendly Nations Visa: $200k real estate or $750k bank deposit + employment letter, fast permanent residency, foreign-income tax-free. Outside 14-Eyes.
  • Mexico Temporary Resident → Permanent: $108k in savings demonstrated. Permanent after 4 years.
  • Paraguay: deposit ~$5,000 (the exact route is being reformed; verify before committing). Permanent residency. Citizenship in 3 years. Genuinely cheap; lighter infrastructure.
  • Uruguay: tax residency by living 60+ days/year, "Vacaciones Fiscales" 11-year foreign-income tax holiday for new residents.

#Second-passport descent pathways

  • Italy (jure sanguinis): rules tightened March 2024 and again 2025. The new law (Decreto Tajani, March 2025) limits to two generations back (parent or grandparent must be Italian-born), eliminating the previously unlimited 1861-cutoff line. Existing applications grandfathered for now but disputed. Honest read: harder than it was, still possible if you have a parent or grandparent born in Italy.
  • Ireland: Foreign Births Register, one generation back (grandparent born in Ireland). Straightforward.
  • Poland: confirmation of Polish citizenship for descendants. Documents required: birth/marriage/naturalization papers showing unbroken chain. Slow but works.
  • Hungary: simplified naturalization for descent. Hungarian-language exam required.
  • Lithuania: descent + restoration for pre-1940 emigrants.
  • Latvia: similar, narrower.

#Naturalization-by-residence timelines

Country Years required Notes
Argentina 2 Famously fast
Paraguay 3 Cheap, lighter infrastructure
Portugal 5 After legal residency; A2 Portuguese
Mexico 5 (or 2 if married to Mexican) Spanish exam
Spain 10 (2 for Latin Americans, Sephardim)
Uruguay 3 (married) / 5 (single) "Legal residence" interpretation varies
Brazil 4 (1 for Portuguese-speaking countries)

#Five (Six) Flags theory, 2026 reality check

The classic "Perpetual Traveler" framework (Harry Schultz / W.G. Hill, refreshed by Andrew Henderson at Nomad Capitalist) says: split the legal life across countries to minimize the claim any one state has on you.

Flag Definition Reality for a US citizen
1. Citizenship (passport) Where you're a citizen US can't be escaped without renunciation. Second passport adds optionality, not tax relief.
2. Residency Where you legally reside Pick low/no income tax (UAE, Bahamas, Monaco — or US states like FL/TX/SD/WY)
3. Banking Where your money lives Wise, Schwab, plus one offshore for diversification (Singapore, Switzerland, Liechtenstein)
4. Business Where your business is LLC in WY/DE/NV, or offshore IBC (BVI, Cayman). Watch CFC/Subpart F rules as US citizen
5. Assets Where your investments sit Brokerage in US (Schwab, Fidelity, IBKR) is fine. Crypto self-custody. Real estate diversified
6. Play Where you spend time Cheap, safe, good internet, low friction

Honest take: a lot of "Five Flags" content online is YouTube grift selling overpriced Caribbean passports. The real strategy for a US citizen with $250k income is narrower:

  1. Set up SD/FL/TX domicile (state tax flag).
  2. Maximize FEIE if physical presence permits (federal tax flag).
  3. S-corp election on 1099 income (SE tax flag).
  4. Banking: Schwab + Fidelity + Wise + one international.
  5. Get a backup passport over 5-10 years (Italy descent if eligible, else Portugal naturalization).

#Perpetual Traveler reality for US citizens

You cannot escape US federal income tax without renouncing. The US is one of two countries (the other is Eritrea) that taxes worldwide income of citizens regardless of residence. So:

  • FEIE (Foreign Earned Income Exclusion): $126,500 for 2024, indexed to inflation, so likely $130-135k by 2026. Requires either the Bona Fide Residence Test (full tax year abroad with intent) or the Physical Presence Test (330 days outside the US in any 12-month period).
  • Foreign Housing Exclusion: stacks on top of FEIE, additional ~$15-35k depending on city.
  • Foreign Tax Credit: if you pay foreign tax, you can credit it against US tax. Mutually exclusive with FEIE for the same income.
  • Self-employment tax (15.3%): FEIE does NOT exclude this. You still owe SE tax. Workarounds: foreign corporation (complex, CFC rules), totalization agreement country (Korea, Japan, most of Europe).

The foreign-resident play for a US citizen is mostly about state tax avoidance, not federal. Federal at 22-24% effective on $250k is what it is.

#Crypto rails for cross-border
  • USDC on Base or Solana: cheap, fast, on-ramp via Coinbase or Kraken, off-ramp via local exchange in destination (Bitso in Mexico, Bitfinex in many places, P2P via Binance in Argentina).
  • Never carry seed phrases across borders. Use Casa multisig (https://casa.io) or self-managed Shamir backup with shares pre-positioned.
#Capital controls to know
  • Argentina: significant. Multiple official exchange rates, formal restrictions on USD purchase. Use Western Union for blue rate; track DolarHoy.
  • China: $50k/yr individual outflow cap, FX scrutiny.
  • India: FEMA. LRS allows $250k/yr remittance outbound.
  • Russia: don't.

#5. Housing

#Long-term rental hacks

#28+ day Airbnb / VRBO discount

Default Airbnb discount for monthly stays is 20-40%. Many hosts will negotiate further. Pre-platform negotiation (going off-app) is technically a TOS violation and risky, no platform protections if it goes bad. The smart play: book first month on-platform, negotiate next stay direct with the same host once trust is established.

#House-sitting

Honest: house-sitting is competitive for desirable locations. Build reviews by taking unsexy first sits (remote cabins, weird pet combos).

#Hostels long-stay

Many hostels offer monthly rates of $300-$600 in cheap geographies. Private rooms in good hostels in Bangkok, Lisbon, Tbilisi can be $500-$900/mo all-in (utilities/coworking/coffee included). Not ideal at 30 but works for stretches.

#Co-living

Brand Price/mo Cities Notes
Selina (https://www.selina.com) $700-$1500 100+ globally Variable quality, sometimes flaky
Outsite (https://www.outsite.co) $1500-$2500 25+ Premium, members-only, dependable
Habyt (https://www.habyt.com) $700-$1800 EU + Asia + US Largest, growing
KASA $1500-$3000 US-mostly Hotel-style monthly
Roam (defunct in some markets, check) $1800-$2800 Bali, Lisbon, etc. High-end
Common $1200-$2200 US NYC, LA, etc.

Co-living bundles wifi, coworking, community, sometimes meals. Useful for landing in a new city without logistics overhead.

#Monastic / retreat / religious hospitality

  • Wat Suan Mokkh (Thailand, https://www.suanmokkh.org): 10-day silent retreats, ~$30/day donation, real Buddhist tradition.
  • Plum Village (France/Vietnam/Thailand, https://plumvillage.org): Thich Nhat Hanh's tradition, 1-3 week stays.
  • Tergar Monasteries (various): Mingyur Rinpoche lineage, retreats.
  • St. Benedict's Rule of Hospitality: most Benedictine monasteries in Italy, France, Spain, and the US take guests for 3-7 day stays for "modest donation." Examples: Monastero di Camaldoli (Italy), Monastère de Solesmes (France).
  • Christian Hospitality Network: pilgrims along the Camino de Santiago can stay in albergues for €5-15/night.
  • Hindu ashrams: Sivananda (Rishikesh), Isha Yoga (Coimbatore, India), ISKCON (worldwide). Donation-based, structured days, some require yoga participation.

These are not tourist hostels. Show up with intent. Most expect participation in morning prayer/practice.

#Work-trade

#Cheapest functional metros, 2026: 1BR rent + internet quality

City 1BR rent (USD/mo) Internet Notes
Tbilisi, Georgia $400-$700 Gigabit widely (Caucasus Online, MagtiCom) Best nomad infra outside SE Asia
Chiang Mai, Thailand $300-$600 1 Gbps, $20-$30/mo (3BB, AIS) Largest nomad scene
Da Nang / Hanoi, Vietnam $300-$500 1 Gbps fiber, ~$10/mo (Viettel, FPT) Fastest cheap internet on earth
Da Lat, Vietnam $250-$400 100-500 Mbps Cooler climate
Medellín, Colombia $500-$800 300-500 Mbps (Claro, Tigo) Best LatAm nomad city
Mexico City $500-$1100 200-500 Mbps (Izzi, Totalplay) Roma/Condesa $800-$1100, edges cheaper
Oaxaca, Mexico $400-$700 100-300 Mbps Lower cost, slower net
Lisbon, Portugal $900-$1500 1 Gbps (MEO, NOS) Expensive now
Porto, Portugal $700-$1200 1 Gbps Lisbon-lite
Tirana, Albania $300-$500 100-300 Mbps (ALBtelecom) Underrated
Yerevan, Armenia $400-$700 100-500 Mbps Cheap, safe
Penang, Malaysia $400-$700 500 Mbps-1 Gbps (Unifi, Time) Time Fibre is excellent
Kuala Lumpur $500-$900 1 Gbps Better infra, higher cost
Bali (Canggu/Ubud) $500-$1000 50-300 Mbps, patchy Power outages common
Bishkek, Kyrgyzstan $200-$400 50-200 Mbps Cheapest, lightest infra
Almaty, Kazakhstan $400-$700 100-500 Mbps Underrated, post-2022 exodus boost
Buenos Aires $400-$800 (USD blue) 300 Mbps-1 Gbps Currency volatility, blue dollar
Cape Town $500-$1000 1 Gbps (Vumatel) Loadshedding requires UPS

For Kris specifically, Tbilisi is the winner. 1-year visa-free entry, gigabit internet widely, low cost, safe, Latin alphabet adjacent, growing English. Chiang Mai is the runner-up, slightly cheaper but Schengen / Schengen-adjacent travel from Asia is a longer haul.

#6. Expenses Driven to Floor

#Cell / connectivity

Option Cost Best for Limit
Google Fi Unlimited Plus $65/mo solo, $50/line family International data in 200+ countries Throttled to 256 Kbps after 50 GB, "primarily US" rule (must use majority in US)
T-Mobile Magenta MAX / Go5G+ $90/mo Free unlimited international 2G/4G in 215 countries, 5GB high-speed Same caveat, must be primarily US
Airalo (https://www.airalo.com) $5-$50 per region eSIM Short trips, one-country eSIM-only, data-only
Holafly (https://esim.holafly.com) $19-$99 per package Unlimited-data trips Pricier per GB but unlimited
GigSky $10-$40 Coverage in obscure markets Spotty
Nomad (https://www.getnomad.app) $5-$50 Wide coverage, good rates
Saily (NordVPN spinoff) $4-$40 Linked to NordVPN ecosystem
Local SIM $5-$30 Long stays Acquiring as a non-resident varies; some countries require local ID

Recommendation: keep T-Mobile or Google Fi as the US-rooted line (Google Voice forwards to it), use eSIMs (Airalo for short trips, Holafly for unlimited-data needs) as the primary data line at destination.

#VoIP / US number maintenance

  • Google Voice (https://voice.google.com): free, works globally over data. Best for the long-haul US number.
  • JMP.chat (https://jmp.chat): SIP-based, $5/mo, real US number, works with any SIP client. Privacy-friendlier than Google.
  • Twilio (https://www.twilio.com): roll your own, ~$1/mo per number plus per-minute. For nerds.
  • Signal username: lets you receive Signal messages without sharing your phone number.

#Food

#Cooking vs eating out
  • Cheaper to eat out: Thailand, Vietnam, Mexico, Indonesia, parts of India. Street food $1-$3/meal, sit-down $3-$8.
  • Cheaper to cook: Western Europe, US, UK, Japan (mostly), Australia, Canada. Groceries are competitive, restaurant markup high.
  • Hybrid: cheap geographies still benefit from cooking breakfast (eggs/coffee) and eating lunch/dinner out.
#Monthly food budget by geography
Geography Monthly food (USD) Composition
Thailand (Chiang Mai) $200-$400 Mostly street food + occasional groceries
Vietnam $150-$300 Pho, banh mi, com tam, very cheap
Mexico $300-$500 Mercado + occasional restaurants
Eastern Europe (Tbilisi, Yerevan, Tirana) $300-$600 Mix cook/eat-out
Bali $300-$500 Warungs cheap, expat food expensive
Western Europe $700-$1200 Mostly cooking + occasional restaurant
US (urban) $500-$900 Cooking-heavy
Japan $400-$700 Konbini + cheap chains + cooking
#Eating-discipline plays
  • OMAD / time-restricted eating: not a fad position, saves real money (one meal of ingredients vs three) and reduces logistics overhead. Many nomads default to this.
  • Soylent / Huel / Jimmy Joy: $2-$4 per meal, complete nutrition, zero time cost. For focus days. Huel Powder is the best balance of cost and macros.
  • The expat-cafe trap: $10 avocado toast + $5 cappuccino x 30 days = $450/mo just on the "feel European" tax. Aware of it = control over it.

#Healthcare floor

  • SafetyWing Nomad Insurance: $42/mo under 40, includes home country up to 30 days per 90.
  • IMG Patriot Platinum: $80-$150/mo, robust.
  • GeoBlue Trekker: $300/yr short-trip, ~$200/mo expat.
  • Direct Primary Care (DPC) in the US when stateside: $50-$100/mo for unlimited GP visits, telehealth, basic labs. Find via https://mapper.dpcfrontier.com.
  • Catastrophic-only US ACA plan: Bronze tier $200-$400/mo, high deductible. Pair with HSA.
  • Dental tourism: Mexico (Tijuana, Cancun), Thailand (Bangkok, Phuket), Hungary (Budapest), Costa Rica. Routine cleaning $30, root canal + crown $400-$800 vs $2,500-$4,000 in US.

#Tax floor

  • State domicile: TX, FL, NV, WA, TN, SD, AK, NH (NH has interest/dividends tax through 2024, repealed 2027). South Dakota is the dominant nomad domicile: low requirements (one night stayed), Escapees RV Club mail service in Sioux Falls (https://escapees.com), or Americas Mailbox (https://www.americasmailbox.com). SD has no income tax, no franchise tax, lenient driver's license rules.
  • FEIE 2026: ~$130k+ projected (indexed for inflation). https://www.irs.gov/individuals/international-taxpayers/foreign-earned-income-exclusion
  • Self-employment / S-corp election: at >$60k of 1099 income, electing S-corp on a single-member LLC pays yourself a "reasonable salary" + distribution. Saves ~15.3% SE tax on the distribution portion. Typical net savings: $6-$10k/yr at $100-$150k income, $10-$15k/yr at $200k+. Setup ~$500-$1500 (Collective, Formations, or a CPA).
  • HSA (Health Savings Account): 2026 limits projected ~$4,400 individual. Tax-deductible going in, tax-free growth, tax-free out for medical. Becomes IRA-like at 65. Requires HSA-eligible HDHP. Triple tax advantage. Best account in the US system.
  • Mega-backdoor Roth: if your 401(k) plan allows after-tax contributions and in-service conversions, you can stash up to $46,500 (the 2024 number, going up) into Roth on top of the regular $23k. Most employees don't have this; freelancers/S-corp owners with a Solo 401(k) can build it.
  • Solo 401(k): best retirement vehicle for self-employed. 2026 limits ~$70k+ between employee + employer contribution. Pair with Mega Backdoor Roth.
  • SEP-IRA: alternative, simpler, but no Roth option.

#7. The Three-Year Glide Path

Year Phase Income target Location Expense ceiling Tax move
Year 1 (2026-2027) US undergrad, pentest/BB starting, first algo deploys $40-80k US (FL or TX domicile; physical wherever undergrad lands) $2,200/mo Establish SD/FL/TX domicile via PMB. Open Solo 401(k).
Year 2 (2027-2028) Income streams mature. Schengen+nomad-visa breaks (Portugal/Georgia/Mexico) during summer/winter terms. $80-160k 60% US / 40% abroad (Schengen quarter, Tbilisi quarter, CDMX/Medellín base) $2,200/mo (US) / $1,500/mo (abroad) S-corp election on 1099 income. Max HSA + Solo 401(k).
Year 3 (2028-2029) Grad school abroad (OIST/EPFL/ETH) or full nomad. Income at target. $200-300k Mostly abroad. Tbilisi or Bangkok base + 3-4 secondary cities $1,500-$2,500/mo Establish bona fide residence or physical presence test for FEIE. State domicile remains SD/FL. Banking diversified (Wise + Schwab + Mercury + one foreign).

Cross-reference with trading.md, pentest.md, bug-bounty.md, open-source.md for income side. The income mix matters for tax strategy: trading gains (LTCG/STCG, no SE tax), pentest 1099 (SE tax, S-corp), bug bounty (1099 misc, S-corp eligible), open-source/grants (often 1099 misc).

#8. Off-grid Optionality

Floor-everything is a strategy, not an identity. Physical resilience matters.

  • STARGATE as eternal anchor: keep STARGATE on Tailscale, accessible from any device worldwide via Tailscale exit node. Personal cloud + dotfile server + Vaultwarden + photo backup + git mirror. The single most important piece of personal infra.
  • Bug-out bag at US home base: 72-hour kit. Cash $1k, 3 days food/water, hard-drive backup of critical data, sat-comm device (Garmin inReach Mini, $400 + $15/mo plan), passport copy, sealed waterproof container with seed phrase share.
  • Physical metals + cash float: $5-10k mixed (3-4 oz gold, 30-50 oz silver, $2k cash) at home base. Not for trading, not for inflation hedge, for power outages, banking system disruptions, emergency relocation cost.
  • Bitcoin cold storage with seed split: 2 physical locations minimum. Use SLIP-39 (3-of-5 or 2-of-3) so loss of one share doesn't destroy access. Memorized passphrase as a third factor.
  • Backup passport application in motion: even if it takes 5 years, start. Italy descent if eligible, else Portugal residency clock.

#9. Things Worth Spending Real Money On

Floor-everything fails when it hurts the work. Pay full price for:

  • Bandwidth and mobile data: never cheap out on internet. Day-rate Holafly for unlimited data is worth it during travel. Pay for the fiber upgrade at base.
  • Keyboard: split mechanical. ZSA Voyager ($365, https://www.zsa.io/voyager) or Kinesis Advantage 360 ($459) or Moonlander Mark I ($365). Travel-ready Voyager fits in a backpack.
  • Chair when stationary: used Herman Miller Aeron or Steelcase Leap ($400-$700 on eBay) beats new $200 chair every time. When nomadic, find apartments with decent chairs included or buy used and resell.
  • Display: 4K 27" or ultrawide when stationary. LG 27GN950-B, Dell U2723QE.
  • Books / scholarly access: ACM membership ($99-$198/yr), arxiv-sanity, physical books for canonical works. Hardcover used from AbeBooks or Better World Books.
  • Health-supporting food: never poison yourself to save $50/mo. Quality protein, vegetables, fermented foods, healthy fats. The downstream cost of cheap food is medical.
  • Travel insurance with extraction: Global Rescue ~$660/yr. Single most important insurance line.
  • Yubikeys: two minimum, three ideal.
  • Reliable banking: Schwab + Fidelity + Mercury + Wise + one foreign. Never single-point-of-failure.
  • Sat-comm in remote travel: Garmin inReach Mini 2 ($400 + service). Saves lives, gets you out of bad places, lets you signal you're alive.
  • Glasses / contacts: if you wear them, two backup pairs, current prescription stored digitally. Lost glasses on the road is a real productivity event.
  • Travel insurance for electronics: not always worth it, but a $30/yr policy on a $2k laptop is a small hedge.
