Property taxes for a new owner

Estimated property taxes about $87,600 a year at the county’s value of this home and its 0.90% tax rate, no exemptions applied

That is about the same as the seller’s bill on the county’s 2026 roll.

If you make this home your primary residence, a homestead exemption would lower this figure. If you have also had a Florida homestead in any of the last three years, you may be able to carry up to $500,000 of its capped-value savings to this home, which Florida calls “portability.” Both are applied for with the Property Appraiser by March 1.

How a new owner’s property taxes are set is explained in the Costs & Taxes chapter of the 2027 Naples Buyer’s Guide.

Estimated from the Collier County Property Appraiser’s 2026 value of this home and its tax rate. The county sets a new value each January 1, so a new owner’s first full bill can differ.

Flood zones & evacuation

Two different things, measured by two different agencies. Evacuation zones are about storm surge and who leaves first. Flood zones are FEMA’s insurance rating, and they vary from home to home.

Hurricane evacuation zone

Zone A Collier

The first zone ordered to evacuate, and the one called in the weakest storms.

Called firstCalled last
FEMA flood zone

Zone AE

1% annual chance, with a set base flood elevation

The building is inside a Special Flood Hazard Area, where a federally backed mortgage requires flood insurance.

FEMA flood maps and Collier County Emergency Management. A revised Collier County flood map is in preparation and may change these zones.

A starting point, not a determination. Your lender will require its own flood zone determination before closing, and your insurer will normally require an elevation certificate — a surveyor’s measurement of how high the building actually sits — before quoting. Those documents govern; this does not replace either. Zones can also be amended individually through FEMA.

Flood zones, evacuation, and insurance are explained in the Risk, Resilience & Insurance chapter of the 2027 Naples Buyer’s Guide.
