A private island retirement sounds like a fantasy, but some islands in the Bahamas now sell for less than luxury homes in many American cities. Consider a couple, ages 67 and 65, with a paid-off $600,000 home, $2 million in retirement savings, and $55,000 a year in Social Security benefits who are considering selling their house and spending $1.2 million on a small developed island. The purchase may be affordable. The challenge is whether the remaining assets can support the lifestyle for the next 30 years.
What $1.2 million Actually Buys in the Out Islands
At this budget, the couple is not shopping for the celebrity-island market. In the Bahamas, a budget of roughly $1.2 million typically buys a small developed island in the Exumas, Abacos, or Berry Islands, often with a modest home, dock, water storage system, generator, septic system, and a workboat. Islands with extensive improvements, guest accommodations, renewable-energy systems, and modern infrastructure generally command much higher prices. Meanwhile, seemingly inexpensive listings are often undeveloped parcels that require substantial additional investment before they are suitable for year-round living.
The Bahamas remains attractive from a tax perspective. The country imposes no personal income tax, no tax on Social Security or pension income, no capital gains tax, and no inheritance tax. Those advantages help explain its popularity with wealthy retirees. The challenge is that avoiding taxes does not eliminate expenses. Maintaining a private island requires a constant stream of spending on infrastructure, transportation, insurance, and repairs, and those costs can quickly overwhelm the tax savings.
The Real Annual Budget
The purchase price is only the beginning. A private island may have no neighbors, but it comes with all the responsibilities of running a small utility company. Property taxes on a $1.2 million island typically run about $8,000 to $9,000 per year, while hurricane and windstorm insurance can cost $15,000 to $25,000 annually, often with substantial deductibles.
The larger expense is infrastructure. Generators, solar panels, batteries, water systems, septic systems, docks, seawalls, and boats all require constant maintenance. Annual fuel costs alone can reach $25,000 to $50,000, while maintaining boats, docks, and equipment can add another $20,000 to $40,000. Many insurers also expect a full-time caretaker on site, a position that can cost $60,000 to $100,000 per year when salary, housing, and related expenses are included.
Daily life is expensive as well. Because most supplies arrive by boat or air, groceries and household goods often cost substantially more than they do on the mainland. A retired couple should budget roughly $25,000 to $35,000 per year for food and supplies, plus $8,000 to $12,000 for boat fuel and transportation between the island and major population centers. Regular trips back to the United States to visit family can easily add another $10,000 to $15,000 annually.
Healthcare is the quiet killer. Medicare Part B premiums apply in 2026, but Medicare does not pay for care outside the United States. The couple will keep paying premiums for U.S. coverage and need an international major-medical plan (roughly $8,000 to $14,000 a year at their ages) plus medical-evacuation membership. A single helicopter evac to Miami without coverage can run six figures.
Mid-range total: roughly $190,000 a year, before income taxes owed in the U.S. on portfolio withdrawals.
Where the Math Lands
Selling the $600,000 home and buying the $1.2 million island pulls $600,000 from the $2 million portfolio, leaving roughly $1.4 million invested. A 3.5% withdrawal on $1.4 million is $49,000. Add $55,000 in Social Security and the couple has about $104,000 a year of reliable income against a $190,000 budget. The gap is roughly $85,000 every year, indexed to inflation that recently ran at 3.77% headline and 3.29% core, with services inflation persistently in the 3.3% to 3.6% range. The plan does not work.
To support the lifestyle at a sustainable 3.5% draw you would need roughly $3.9 million invested after the island purchase, or about $5.1 million in total assets going in. The couple is short by more than $2 million.
A Problem That Gets Bigger With Age
A private island is not a passive investment. It produces no income, requires constant maintenance, and remains exposed to hurricanes, saltwater corrosion, and rising insurance costs. Unlike a traditional home, it cannot simply be locked up and ignored for months at a time.
Liquidity is another concern. The market for developed private islands is small, and sales can take years rather than months. The house the couple sold in the United States might have attracted multiple buyers within weeks. A private island appeals to a much narrower audience, making it difficult to convert back into cash if circumstances change.
The practical challenge grows as the owners age. At 67 and 65, they may be comfortable managing boats, generators, maintenance projects, and supply runs. By their late seventies or eighties, many of those tasks will need to be outsourced. A caretaker may begin as a convenience but eventually becomes a necessity, and labor costs tend to rise faster than general inflation.
That means today’s budget is unlikely to remain today’s budget. Over a multi-decade retirement, increasing maintenance, labor, insurance, and transportation costs can push annual spending dramatically higher. A private island may be affordable at the start of retirement, but the long-term sustainability of the lifestyle is often a much bigger challenge than the initial purchase price.
What Would Make It Work
This couple should not buy a $1.2 million private island with a $2 million portfolio. The version that works keeps the U.S. home as a hurricane fallback and rents a house on Eleuthera, Long Island, or Great Exuma for six months a year, which runs $30,000 to $60,000 annually and preserves both liquidity and Medicare access.
If island ownership is non-negotiable, the math requires roughly $5 million in total assets, a price cap near $700,000 on the island itself, and a serious conversation about delaying any boat or staffing decision until cash flow is observed for two full years. A 3.5% withdrawal rate is the right discipline for a thirty-year horizon, and the 3.75% federal funds rate alongside a 4.49% ten-year Treasury means a conservative bond ladder can do real work inside the portfolio. Two million dollars is enough to retire well in the Bahamas, at a price point below island ownership.
