How we produced these numbers
Based on Florida Department of Revenue Property Tax Oversight (PTO) data portal public assessment roll data (2025 tax year), comparing assessed values with recent comparable sales, normally normalized by recorded square footage when enough data exists. The model also evaluates documented flood location, age-based condition signals and any recent arm’s-length sale; recorded size adjusts the sales comparison and is not scored separately. Figures are county-level estimates produced by an automated model — they are not an appraisal and not a finding about any specific property. Actual results depend on your property and on your county’s Value Adjustment Board. Savings are not guaranteed, and some appeals result in no change.
Coverage: 36,860 single-family parcels on the 2025 assessment roll.

Questions about appealing in Monroe County
How much does an appeal cost in Monroe County?
Our flat fee is $199 for the appeal report and filing packet. The Monroe County Value Adjustment Board also charges its own filing fee — most Florida counties now charge $50 per petition, a few still charge less, and the amount is on your county VAB page. We charge no percentage of any savings.
What is the deadline to appeal property taxes in Monroe County?
25 days from the date printed on your TRIM Notice, which the Monroe County Property Appraiser mails in August. The exact date is on the notice itself.
Will appealing raise my Monroe County taxes?
Filing a petition with the Value Adjustment Board does not by itself raise your assessment. The board reviews the evidence and either lowers the assessed value or leaves it unchanged.
Do I need a lawyer to appeal in Monroe County?
No. Florida homeowners file VAB petitions themselves every year. We are not a law firm and do not provide legal advice — we prepare the evidence packet and the paperwork so you can file it.
How can I reduce property taxes in Monroe County?
There are two levers. First, make sure every exemption you qualify for is on file — the Florida homestead exemption reduces your taxable value and caps annual assessment increases at 3% under Save Our Homes (deadline March 1). Second, if the Monroe County Property Appraiser has your home assessed above what recent comparable sales support, petition the Value Adjustment Board within 25 days of your TRIM Notice. We support the second: we pull the comparable sales and build the evidence packet that you file with the Value Adjustment Board. You submit the petition and you present your case — we are not a law firm and cannot file or appear on your behalf.
