Selling a Florida homestead? You can carry up to $500,000 of its Save Our Homes benefit to your next one. This estimator shows how much transfers, what your new assessed value becomes, and the estimated tax with and without it.
Upsizing • downsizing • joint-owner splits • 2026 indexed exemption
For Florida homeowners moving within the state — and the agents helping them price the move.
Your old home's Save Our Homes cap has probably kept its assessed value far below market. Sell it and move within Florida, and that gap doesn't have to disappear — portability lets you apply it to the new home. Grab the two numbers off your property appraiser's record and see what it's worth.

How your new assessed value is built
Florida Statutes §193.155(8), step by step.
From assessed value to estimated tax
School and non-school taxes are figured separately because the second homestead exemption only applies to non-school levies.

While a home is your homestead, its assessed value can rise no more than 3% a year (or CPI, if lower). After years of appreciation, the gap between just value and assessed value gets big. That gap is the benefit.
If the new home's just value is equal to or higher than the old one's, you subtract the whole gap from the new home's just value — capped at $500,000.
If the new home is worth less, you keep the same percentage: new assessed = new just value × (old assessed ÷ old just). The benefit still can't exceed $500,000.
Portability changes the math on what you can afford next. I'll build the full picture — the tax you'll actually carry, the payment, and how much house the move really buys you.
