You've owned it for twenty years. Selling isn't just a price — it's a tax decision.

Most long-term owners run one number before listing: what the house will sell for. The number that matters more is what's left after taxes, and what your next home costs to own once your assessment resets. For some sellers those two numbers change the decision entirely — and almost no one runs them before calling an agent.

This page is the plain version of the three things that catch long-term Florida owners: the property tax reset, capital gains after decades of appreciation, and the inheritance question nobody wants to raise.

Florida's Save Our Homes rule caps how much your homesteaded property's assessed value can rise each year. After twenty years, your assessed value can sit far below market value — which is why your tax bill feels reasonable. That cap is tied to this house. When you sell and buy another, the new home is reassessed at current market value.

The result catches people off guard: your new, smaller, cheaper home can carry a higher annual property tax bill than the larger home you've owned for two decades.

Portability softens this. It lets you carry a portion of your accumulated Save Our Homes savings to the new homestead — up to a maximum of $500,000 in transferred assessment difference (Florida Statute § 193.155). If you move to a home of equal or greater value, you can carry the full benefit up to that cap; if you downsize, the benefit is prorated. You have three tax years to establish the new homestead, and the application deadline is March 1 of the qualifying year.

It reduces the increase; it rarely erases it. Your exact number depends on your specific values — the Manatee or Sarasota County Property Appraiser is the source of record, and both offer estimators.

Federal law lets you exclude up to $250,000 of the gain on the sale of a primary residence if you file single, or $500,000 married filing jointly — provided you owned and lived in the home at least two of the five years before the sale. For homeowners who bought on the Gulf Coast many years ago, the gain can run past that exclusion, and the excess may be taxable. Improvements you've made over the years can raise your cost basis and reduce the taxable gain, which is one reason keeping records of major work matters.

I'm not your tax advisor, and the specific exclusion figures and rates should come from a CPA who can see your full picture. My job is to make sure this number is on the table before you list, not discovered at closing.

When property passes to heirs, its cost basis generally steps up to the market value at the owner's death. In plain terms: the capital gain that would have been taxable if you sold can be substantially reduced or wiped out for your family if they inherit instead. For some long-term owners, that step-up is worth more to the people they love than anything I could get them on the open market.

This isn't a blanket recommendation — there are real reasons to sell in your lifetime: needing the equity, not wanting to burden heirs with a property, health and care costs, family circumstances. The point is that it's a genuine fork in the road, and you deserve to see both paths before choosing one.
