Check my Key West home, freeHow we measured this
We compared every single-family home in Key West to the median comparable home in the same ZIP, using public county just (market) value from the Florida DOR roll, the value a §194.011 VAB petition actually challenges, not the Save Our Homes-capped assessed value, and counted a home as over-assessed when it sits more than 15% above that median. This is a city-level screen, it shows where over-assessment is common, not whether any specific home is over-assessed. See the full nationwide methodology and ranking. Data as of July 2026.

How do I appeal my property taxes in Key West, Florida?
Your county property appraiser mails a TRIM (Truth in Millage) notice in mid-to-late August showing your home's proposed just (market) value. You then have 25 days, most 2026 deadlines land around September 15, to file a Form DR-486 petition with your county Value Adjustment Board (VAB), for a $15 filing fee per parcel. Under Florida Statute §194.011 the petition challenges your just value, so comparable sales that value your home below the appraiser's figure are the evidence that wins. AppealMyTax builds that pre-filled VAB petition kit for your Key West home for $49 flat, sign and file in about 5 minutes, and you keep 100% of any savings.
When is the Key West property tax appeal deadline?
25 days after your county mails its TRIM notice, which for most Florida counties means mid-September (around September 15, 2026). The Clerk of the Value Adjustment Board must physically receive your DR-486 petition by the deadline, a postmark does not count, so file a few days early. Miss it and you wait a full year for the next window.
Is it worth appealing in Key West if I have a homestead exemption?
Often yes. Winning a lower just value can cut this year's bill, and for a homesteaded home that lower value then becomes the base your 3% Save Our Homes cap grows from, so a single Key West win compounds over every year you own the home. Non-homesteaded homes (rentals, second homes, recent purchases) tend to see the largest immediate reduction because their assessed value tracks market value directly.
Does living in Key West mean my home is over-assessed?
Not necessarily. This is a city-level screen built from public appraisal records, it shows where over-assessment is common, not whether your specific home is over-assessed. The only way to know is a per-home comparison against similar properties nearby, which our free address check does in about 30 seconds.
