The question shows up in nearly identical form in every retirement forum and family group text. A couple who spent a decade in Naples or Cape Coral or Vero Beach is asking whether the numbers still make sense, and a couple who already sold and moved to Greenville or Asheville or Knoxville is telling them the same thing: leave sooner. The tag for this migration already exists. Florida Trend calls them the halfbacks, retirees who went south, went back partway, and stopped in the Carolinas or Tennessee. The regret is almost always about timing.
Why the Florida Budget Stopped Working
Consider a couple, both 68, who bought a coastal Florida condo years ago and now spend roughly $78,535 a year, plus insurance and assessments that have moved on their own timeline. Florida is the most expensive state in the country for homeowners insurance, with an average premium around $7,136, and coastal condo owners routinely quote figures well above that once wind and flood are stacked on the master policy. Layer in property tax on a house that has ridden the Case-Shiller National Home Price Index up to 335.1, a fresh high in the recent series, HOA special assessments in the post-Surfside inspection regime, and utilities that run year-round for cooling, and a working annual budget in Florida for this household lands closer to $95,000 than to the BLS average.
That budget breaks down roughly as: $32,000 for housing carrying costs (insurance, taxes, HOA, maintenance), $18,000 for healthcare, including Medicare Part B at $202.90 a month per person in 2026, a Medigap plan, and dental, $12,000 for food, $9,000 for transportation, $8,000 for travel and gifts, and $16,000 for miscellaneous and reserves. Florida’s cost-of-living index sits at 103.4, above the national benchmark, and the concentration of that overage in housing and insurance is what keeps rising faster than the 2027 Social Security COLA, which is tracking at 3.1%.
What the Tennessee Version Actually Costs
Move the same couple to a mid-sized Tennessee metro, and the line items reset. Tennessee’s cost-of-living index is 91.9, with real income of $72,154 versus Florida’s $70,919. Tennessee has no state income tax on wages, pensions, IRA and 401(k) withdrawals, or Social Security, matching Florida’s treatment and preserving the tax move rather than surrendering it. Tennessee ranks 8th on the 2025 State Tax Competitiveness Index, just behind Florida at 4th. Housing carrying costs on a similarly sized home drop by roughly a third once insurance normalizes to a non-catastrophe market, and property taxes on inland Tennessee homes tend to run lower than on comparably valued Florida coastal condos even before homestead resets.
A realistic Tennessee budget for the same lifestyle: $18,000 housing carrying costs, $18,000 healthcare, $11,000 food, $8,000 transportation, $8,000 travel and gifts, $9,000 miscellaneous and reserves. That is $72,000 a year, versus $95,000 in Florida.
Math That Turns Regret Into a Number
Now look at what happens when both partners claim at the current retired-worker average of roughly $2,084 a month each. That produces about $50,000 a year in household Social Security. In Florida, the gap comes to $45,000 a year, which, at a 4% withdrawal rate, requires a portfolio of about $1.125 million. In Tennessee, the gap drops to $22,000 a year, which, at that same 4% rate, requires only about $550,000. That means the move from Florida to Tennessee is worth roughly $575,000 in required portfolio, or about $23,000 a year in withdrawals the couple no longer has to take. Over a 25-year horizon, with CPI at 332.8 and rising, the compounded savings dwarf the one-time transaction costs of making the move.
Compounding Trap Most Sellers Underprice
Movers consistently say they should have gone five years sooner because every additional year in Florida quietly resets the exit price in ways you do not see coming. Insurance renewals hit in double-digit percentages. A special assessment arrives in a single letter. A roof replacement gets priced against a shrinking pool of insurers. And the buyer pool itself is already pricing in those same carrying costs. Existing home sales nationally are running at 4.06 million annualized, which is widely considered a soft range, and that softness is concentrated exactly where insurance and assessments have moved fastest. Consumer sentiment sits at 49.5, which is below the recessionary threshold of 60, further thinning the pool of potential buyers.
Selling a long-held Florida homestead often bunches capital gains into a single tax year. That spike in modified adjusted gross income can push a couple into the Medicare Part B IRMAA tier that starts above $218,000 in joint MAGI, adding $81.20 a month per person on top of the standard $202.90 premium, and it lands two years later on the Medicare bill. Sellers who wait until every carrying cost has ratcheted higher end up paying the exit tax on a slower-selling asset. Those who moved earlier sold into a thicker market, split gains across quieter tax years using primary-residence exclusions cleanly, and avoided the IRMAA surcharge on the following year’s premiums.
What It Actually Takes
For the Tennessee version of this retirement, the working number is a paid-off or nearly paid-off home purchased with Florida sale proceeds, a portfolio of roughly $550,000 to $650,000 in a mix of index funds, dividend ETFs, and a short treasury ladder for near-term withdrawals, both spouses claiming Social Security at or near full retirement age, and a 4% withdrawal rate (the 4% figure itself is worth pressure-testing, and we made the case for an income-first alternative in a free report). The Florida version of the same lifestyle requires closer to $1.1 million and a household willing to absorb an insurance market that keeps repricing. The five-year regret is really a statement about compounding: the sooner the sale clears, the more of that $23,000 annual gap becomes portfolio growth instead of an insurance premium.
