Florida Save Our Homes Portability: The $500,000 Tax Benefit That Follows You When You Downsize

If you've owned your Florida home for 20+ years and you're thinking about downsizing, the single most valuable benefit on the table isn't your sale price. It's a Florida-specific tax mechanism called Save Our Homes (SOH) portability, and it can save the right homeowner thousands of dollars per year for the rest of their life in a new home.

What Save Our Homes does

Florida's Save Our Homes amendment caps annual increases in assessed value on a homestead-claimed property at 3% per year (or the CPI, whichever is lower). Over 20-40 years, the gap between assessed value and market value compounds enormously. A long-term Lighthouse Point homeowner might have a $4M+ market-value home but a $1.27M assessed value — they pay property tax on the $1.27M number, not the $4M.

What portability does

When you sell that homestead and buy a new Florida homestead within two assessment years, you can port up to $500,000 of the difference between assessed and market value to the new property. The new home's assessed value starts discounted by that ported amount, dropping its tax bill significantly — sometimes by thousands of dollars per year — for as long as you own it.

Worked example

A widow has owned her Lighthouse Point home since 1985. Market value $4.5M, SOH-capped assessed value $1.27M — a $3.23M gap. She sells and buys a $1.5M condo in The Villages. Florida lets her port up to $500K of the SOH benefit. Her new condo's assessed value: $1.5M minus $500K = $1.0M. At ~1.8% millage, her property tax on the new condo is about $18,000/year instead of about $27,000/year — a $9,000-per-year saving that follows her until she stops owning the property.

The deadline that catches people off-guard

Portability has a clock. You must file a new homestead exemption (and a portability application, Form DR-501T) on the new property by March 1st of the second year following the sale of your prior homestead. Miss it and the benefit is lost. We've seen $9,000-per-year benefits walked away from because the new homestead paperwork wasn't filed timely.

Where this matters for our investor introductions

When we structure off-market acquisitions for long-term Florida sellers — the wholesale-style introductions documented on the Project Management page — we always include a CPA referral and a Portability planning conversation. The cash from the sale is one number. The lifetime tax savings on the next homestead is a second, separate number, and it's frequently bigger than people realize.
