Florida Homestead Portability for Miami Sellers
How does Florida homestead portability work when you sell your Miami home?
Florida's portability rule lets you transfer up to $500,000 of your Save Our Homes assessment cap from your current Miami homestead to a new one anywhere in Florida. If you move up to a higher-value home, you keep the full benefit (up to the $500,000 cap). If you move down, you keep a proportional share based on the ratio of the new home's market value to the old one's. You apply by filing Florida Department of Revenue form DR-501T together with your new homestead exemption application by March 1, and you must establish the new homestead by January 1 of the third year after leaving the old one.
If you've owned your Pinecrest, Coral Gables, or Palmetto Bay home for ten or fifteen years, your assessed value is almost certainly tens of thousands (if not hundreds) of dollars below your market value. (You can find both your market value and your assessed value on your property’s tax sheet at miamidadepa.gov - then do a property search by address or by your name.) That gap is your Save Our Homes benefit, and it's the single biggest reason your property tax bill is lower than your neighbor's who bought last year.
When you sell and buy again in Florida, you don't have to walk away from that benefit. Florida's portability rule lets you take it with you (as long as you buy within a certain amount of time). But the rule is full of small mechanics that trip up otherwise-careful sellers — and the difference between using it correctly and missing the deadline can mean tens of thousands of dollars over the life of your next home.
Here's exactly how it works.
What Save Our Homes actually caps, and how it builds value over time
Florida's Save Our Homes (SOH) amendment caps the annual increase in your homestead's assessed value at 3% or the change in the CPI, whichever is lower. Market value can do whatever the market does. Assessed value can't outrun that 3% line.
Over time, the gap between the two grows. That gap is your Save Our Homes benefit.
A Pinecrest homeowner who bought in 2010 might have a market value of $3.5 million today and an assessed value of $900,000. That's a $2.6 million SOH benefit. A Coral Gables family in a Mediterranean Revival home they've owned since the early 2000s might have an even larger one. A South Miami homeowner who bought in 2018 will have a smaller benefit but still meaningful, often $200,000 to $400,000.
The benefit only matters when you act on it. Either you stay (and keep paying property tax on the lower assessed value), or you sell — and decide whether to port the benefit to your next Florida home.
How much you can transfer: the two scenarios
Portability splits cleanly into two cases.
Moving up (new home is worth more than your old one). You can transfer your full SOH benefit, capped at $500,000. If your benefit is $1.6 million, only $500,000 comes with you. The other $1.1 million is gone.
Moving down (new home is worth less than your old one). You transfer a proportional share. The math is simple:
New benefit = (New market value ÷ Old market value) × Old SOH benefit
So a Coral Gables seller with a $3 million market value and a $1.2 million SOH benefit who downsizes to a $1.5 million Coconut Grove condo would calculate:
(1,500,000 ÷ 3,000,000) × 1,200,000 = $600,000 of benefit — then capped at $500,000.
That $500,000 is subtracted from the new home's market value to set its starting assessed value. The Coconut Grove condo, instead of being assessed at $1.5 million, would get assessed at roughly $1 million in year one. Save Our Homes then caps annual increases on that lower base going forward.
That single mechanic is worth real money over the long run. In Miami-Dade, combined millage rates typically land in the 19–23 range per $1,000 of assessed value depending on the municipality and special districts. On a $500,000 reduction in assessed value, you're saving roughly $9,500 to $11,500 a year in property tax — every year you own the new home.
The deadlines almost everyone misses
Portability doesn't transfer automatically. You have to file for it.
You file Florida Department of Revenue form DR-501T (Transfer of Homestead Assessment Difference) together with your new homestead exemption application at the Miami-Dade Property Appraiser's office (all of which can be done online). The deadline is March 1 of the year you want the exemption to first apply.
You also have a hard window to use the benefit at all: you must establish your new Florida homestead by January 1 of the third year after abandoning the old one. If you sold your Pinecrest home in 2025, you have until January 1, 2028 to make a new home your primary Florida residence and keep the portability option alive. Miss that window and the benefit disappears.
If your previous home was jointly owned, all owners have to abandon the homestead for the assessment difference to transfer. This catches divorcing couples and family ownership structures that haven't been updated.
Why portability changes how you should think about selling in Miami
If you've been on the fence about listing your Coral Gables or Pinecrest home, the portability conversation often shifts the math.
Long-tenured owners sometimes assume they're "trapped" by their low tax base — that selling means handing over the SOH benefit and starting over. That's only half right. You give up the part above the $500,000 cap, but you keep the most valuable slice and apply it to the new home.
You also have flexibility. You can sell now and buy later (within the three-year window). You can downsize and still port a meaningful share. You can move from Pinecrest to Cocoplum to Old Cutler Bay — anywhere in Florida — and the benefit follows you.
For sellers in the $2 million to $5 million range across Coral Gables, South Miami, Pinecrest, and Palmetto Bay, this is a routine part of the pre-listing conversation I have with clients. We map out the SOH benefit, the likely portability transfer, and what the new home's assessed value will look like before we even talk about pricing strategy. It changes what "trading up" or "trading down" really costs.
If you're also weighing the broader cost of selling — commission, doc stamps, title fees, and attorney fees — my full breakdown of what it costs to sell your Miami home covers the rest of that picture. And when you're ready to move from planning to listing, the Miami pre-listing checklist walks through the prep that protects your sale price.
Common mistakes I see Miami sellers make
Selling too far ahead of buying. Three years sounds long until you're house-hunting in a tight market. If your timeline slips past January 1 of the third year, the benefit is gone.
Forgetting to file the DR-501T. Filing for homestead alone doesn't port the benefit. The transfer form is separate, and it's due by March 1. I send all of my clients a reminder to apply for their homestead exemptions so they don’t have to remember, but I doubt every realtor in Miami does this…
Assuming a downsize means losing everything. The proportional formula usually leaves you with more transferable benefit than sellers expect.
Co-owner issues on the old homestead. If both spouses or all family members on the deed don't abandon the previous homestead, the transfer is blocked.
Trying to port to a non-homestead property. Portability is for primary Florida homesteads only. A move from Coral Gables to North Carolina forfeits the benefit. So does a move into a vacation property or a primary residence held by an LLC or trust that doesn't qualify for homestead.
The Property Appraiser's office is the final word on every individual case, so I always recommend verifying your specific numbers with the Miami-Dade Property Appraiser's portability calculator before you make a final decision.
Frequently Asked Questions
Can I port my homestead exemption to a vacation home or rental property?
No. Portability only applies between primary Florida homesteads. If your next home doesn't qualify for the homestead exemption — for example, a vacation property where you don't make Florida your permanent residence — you can't transfer the SOH benefit there.
How long does it take Miami-Dade to process a portability transfer?
If you file your homestead application and DR-501T together by March 1, the Property Appraiser typically processes both for the same tax year. You'll see the transferred benefit reflected on your Notice of Proposed Property Taxes (TRIM Notice) in August.
What if I sold my Coral Gables home a year ago and I'm only now buying in Pinecrest?
You're fine, as long as you establish your new homestead by January 1 of the third year after you abandoned the old one. A 2025 sale gives you until January 1, 2028. File the DR-501T with your new homestead application after you move in and the appraiser's office takes care of the rest.
Does portability work if I move from Miami-Dade to another Florida county?
Yes. Portability is statewide. You can move from Pinecrest to Naples, from Coconut Grove to Sarasota, from Coral Gables to Tampa — the SOH benefit follows you to any qualifying Florida homestead. The receiving county's Property Appraiser processes the transfer.
What if my new home is much more expensive than my old one — does my whole benefit transfer?
You can transfer your full SOH benefit, but only up to the $500,000 statewide cap. If your benefit was $1 million, only $500,000 comes with you. The remainder is forfeited. This is the part that surprises a lot of Coral Gables and Pinecrest sellers with very long ownership histories — the cap is real, and it doesn't move with inflation.
