Let's be real. For most retirees, only one Caribbean island actually works

A couple in their early sixties wants sun, warm water, a slower pace, and lower cost of living, so they research the Caribbean. Then reality sets in. Medicare doesn't travel. Foreign residency permits have income floors. Local healthcare is uneven. Currency risk, hurricane exposure, and property titling turn fantasy into a project. When you stack practical constraints against financial ones, there is really only one Caribbean island where the math works for a typical American retiree: Puerto Rico.

Why Puerto Rico Is the Only One That Actually Pencils

Puerto Rico is a US territory, and that status carries real, practical weight. Social Security direct-deposits into a mainland bank without conversion, Medicare Parts A, B, C, and D function normally, the currency is the dollar, and you can drive there with a US license and fly there without a passport. Every other island requires you to either self-insure healthcare, buy a foreign expat policy, or fly back to the mainland for anything serious. That single fact eliminates Aruba, the Caymans, the DR, and every other candidate for the median retiree.

Your IRA and 401(k) distributions, pension, and Social Security remain under the same federal rules you already know. The famous Act 60 incentives apply to active investors and business owners, not to retirees living off portfolio withdrawals, so plan around ordinary retiree tax rules.

The Real Cost Picture for a Couple Around Age 65

Skip San Juan proper unless you want mainland-metro prices. The retiree sweet spots are the west coast around Rincon and Aguadilla, the south coast around Ponce, and smaller east-coast towns. A comfortable two-bedroom condo with an ocean view runs roughly $275,000 to $375,000, or rent in the $1,600 to $2,200 monthly range. Property taxes are often under $1,200 a year on a modest condo.

Annual budget in current dollars for a couple who own outright:

• HOA, wind and hazard insurance, property tax: $9,000
• Electricity, water, internet, phones: $5,400
• Food and household: $11,500
• Medicare Part B, Medigap or Advantage premiums, dental, out of pocket: $8,400
• One vehicle, fuel, insurance, maintenance: $5,500
• Travel back to the mainland twice a year: $4,500
• Miscellaneous, gifts, entertainment, restaurants: $7,000
• Home reserves, vehicle replacement, income taxes: $6,700

That totals about $58,000. Renters should add roughly $12,000 a year and drop the HOA and insurance line, landing near $61,000. For context, the BLS puts average US household spending at $78,535 in 2024, so the island buys you a real, but not enormous, discount.

The Math From Budget to Portfolio

Assume a couple claiming at full retirement age, generating combined Social Security of about $44,000 a year. The 2.8% COLA for 2026 keeps that number moving with prices, which matters because CPI sits at 332.6 and core PCE keeps grinding higher.

Subtract $44,000 from a $58,000 budget and the annual portfolio gap is $14,000. At a 4% withdrawal rate, that requires a nest egg of $350,000. Add a $60,000 buffer for a generator, solar, and roof reserves, and call it $410,000 of investable assets on top of a paid-off condo. If you are renting instead, the gap grows to about $17,000, pushing the target to roughly $425,000 plus a rent reserve. A treasury ladder yielding near the 4.58% ten-year, paired with a broad index fund sleeve and a dividend ETF sleeve, covers the withdrawal without heroics. Skip bank CDs at the 1.65% national average; they lose to inflation.

The Line Item Nobody Prices Correctly

Wind and hazard coverage on a coastal condo can run $2,500 to $4,500 a year and climbs after every named-storm season. A whole-home generator or solar-plus-battery setup keeps insulin cold and the AC running during multi-day outages, making it essential rather than optional. Budget $18,000 to $35,000 up front and roughly $1,200 a year in maintenance and fuel. Over a thirty-year retirement, that stack quietly eats an extra $80,000 to $120,000 that mainland budgets never see.

Medicare Advantage networks in Puerto Rico are strong for routine care, but skilled nursing capacity is thin. Plan on a mainland exit option in your late seventies or a dedicated long-term care reserve of $150,000 per spouse.

What It Actually Takes

For a couple around 65 who own a modest condo outright, Puerto Rico works on roughly $410,000 to $500,000 of investable assets, drawn at 4%, alongside average Social Security. Renters need closer to $550,000 to $650,000. Add a hurricane and power reserve of $30,000 and an LTC reserve of $150,000 per person, and the realistic all-in target lands between $750,000 and $950,000 plus the home. Anything less and you are one storm, one hospitalization, or one bad year away from moving back.
