Florida Homestead Portability and Your Next Mortgage Payment

Selling one Florida home and buying another can change the tax part of your new payment.

If your old home had a Florida homestead exemption, you may be able to transfer part of its Save Our Homes benefit. This is called portability. It may lower the assessed value of your new Florida homestead.

A lower assessed value may lower property taxes. If your loan uses escrow, that may lower the tax part of your monthly payment. Portability does not change your loan amount, interest rate, or principal-and-interest payment.

It also does not guarantee loan approval.

Homestead exemption and portability are different

These terms are related, but they are not the same.

• Homestead exemption is a tax benefit for a Florida primary residence. The general exemption can reduce taxable value by up to $50,000. Part of the exemption does not apply to school taxes.
• Save Our Homes limits annual increases in the assessed value of an eligible homesteaded home. The limit is generally the lower of 3% or the change in the Consumer Price Index.
• Portability may let an eligible owner transfer all or part of the gap between the old home's just value and assessed value to a new Florida homestead.

Your old homestead exemption does not move to the new home. You must apply for a new exemption. You may also apply to transfer the old Save Our Homes assessment difference.

How portability may affect your payment

Your total mortgage payment may include principal, interest, mortgage insurance, homeowners insurance, and property-tax escrow.

The Consumer Financial Protection Bureau explains that the Loan Estimate may show property taxes and insurance in the estimated total monthly payment. The tax amount is an estimate. Local taxing authorities set property taxes, not the lender.

If the county approves portability and the benefit lowers your tax bill, the escrow portion of your payment may be lower. Your servicer may later change the escrow amount after it receives the actual tax bill.

What may transfer to your next home

Just value is the property appraiser's estimate of market value for tax purposes. Assessed value is the value used before exemptions are applied.

Years of Save Our Homes protection can create a gap between those values. That gap is the assessment difference.

When you sell, the buyer does not receive your old assessed value. The property is generally reassessed after the ownership change. If you qualify, you may be able to transfer some or all of your assessment difference to your new Florida homestead.

The transferred reduction is generally limited to $500,000.

The property appraiser makes the final calculation. The result can depend on the old and new just values, ownership, residency, exemptions, county records, and timing.

Simple planning example

Suppose your old home had a just value of $500,000 and an assessed value of $350,000. The assessment difference would be $150,000.

If your new home had a just value of $600,000, portability might reduce its assessed value by some or all of that amount before exemptions are applied. This is only an example. It does not confirm eligibility or predict your tax bill.

Do not use the seller's tax bill as your budget

A seller's tax bill may reflect years of homestead protection. It may not show what you will pay as the new owner.

This matters when you compare homes in St. Petersburg and Pinellas County. Review the new home's tax record, your possible portability benefit, and a cautious payment estimate together.

Ask the county property appraiser about the new home's likely assessment. Ask your lender what tax figure was used for the payment estimate.

Watch the filing dates

Florida generally requires you to own and occupy the home as your permanent residence on January 1 to claim the exemption for that tax year. The usual filing deadline is March 1.

For portability, file Form DR-501T with Form DR-501 for the new homestead. The Florida Department of Revenue says the deadline is March 1 of the first year after you move.

For example, if you move into your new primary home during 2026 and live there as your permanent residence on January 1, 2027, the normal filing deadline is March 1, 2027.

Florida allows portability when the prior homestead exemption was in place on January 1 of one of the three immediately preceding years. Pinellas County describes this as three tax years. It is not simply three years from the date you sold.

The rules can be hard to apply when you rent, move between counties, or wait to buy. Contact the property appraiser as soon as you know your moving plan.

Steps to take before making an offer

1. Save the old home's latest tax bill and property-appraiser record.
2. Check the old just value and assessed value.
3. Review the new home's tax record. Treat the seller's tax bill as background only.
4. Ask the new county property appraiser about eligibility, forms, records, and deadlines.
5. Tell your loan officer that you may apply for portability.
6. Review the Loan Estimate. Check the estimated taxes, insurance, assessments, and escrow amount.
7. Keep room in your budget for a later escrow change.

Ask your lender what annual tax amount was used. Also ask whether the estimate assumes a seller's exemption, a new-owner assessment, or another figure.

What can change after closing

The county may update the property's value after closing. Your servicer may later review escrow using the actual tax and insurance bills.

If the bills are higher than expected, your escrow payment may rise. If they are lower, your account may have a surplus. Your servicer will explain how any shortage, surplus, or payment change is handled.

Frequently asked questions

Can I keep my Florida homestead exemption when I move?

No. The exemption itself does not transfer. You must apply for a new exemption.

You may be able to transfer the Save Our Homes assessment difference.

Does portability happen automatically?

No. You must apply through the county property appraiser. File Form DR-501 for the new homestead and Form DR-501T for portability by the applicable deadline.

Can portability work between Florida counties?

It may. The old and new property appraisers can exchange information. The application asks for details about the prior home.

Will portability lower my payment right away?

Not always. It may lower the tax and escrow part of the payment after the county approves the benefit and the tax record reflects it. It does not lower the principal-and-interest payment.

Plan with the full payment in mind

Portability can help you estimate the tax side of a move-up purchase. But it is only one part of your housing cost.

Review the purchase price, loan terms, insurance, property taxes, HOA dues, and possible escrow changes together. You can also read Questions to Ask a Florida Mortgage Lender Before an Offer and How to Compare Mortgage Loan Estimates in Florida.
