⚠️
Property taxes in Florida are reassessed after a sale, so a buyer’s first full-year bill can be higher than the seller’s. Budget from this estimate, not the current bill, before you make an offer.
Current owner’s estimated bill $37,375/yr ($3,115/mo) — taxable value $3,829,684 × 9.76 mills
$6,925 more each year
(+19%)
Most of this comes from Florida’s Save Our Homes assessment cap resetting when the home sells — the current owner’s protected assessment does not transfer to a new buyer.

Frequently asked questions
How big is 3820 E County Highway 30A #UNIT 201 and when was it built?
Per the listing record, 3820 E County Highway 30A #UNIT 201 was built in 2018 and has 4 bedrooms and 3.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 3820 E County Highway 30A #UNIT 201 in?
3820 E County Highway 30A #UNIT 201 is in Thirty One, A Condominium Development in Santa Rosa Beach, Walton County. Too few comparable closed sales exist nearby for this page to show local sales statistics; a licensed agent can prepare a comparative market analysis.
Why might property taxes on 3820 E County Highway 30A #UNIT 201 differ from the current owner's?
The estimate on this page (about $44,300 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $6,925 more per year than the current owner’s estimated bill (+19%). Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 3820 E County Highway 30A #UNIT 201 in a flood zone?
A flood designation has not been verified for this address. Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) and confirm with your insurer.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.

Opinion & estimate — do not rely on this page.

These figures may be inaccurate or out of date, are not appraisals, valuations, or financial, legal, tax, or investment advice, and should not be relied upon. Do not make any purchase, offer, financing, or other decision based on this page. Independently verify everything — price, square footage, lot size, year built, taxes, CDD/HOA, flood status, school assignments, permits, and community rules — with the listing broker, the county, your lender, a licensed inspector, an insurer, and your own advisors before acting.
Estimate methodology. Tax estimates apply county millage to the list price (less the homestead exemption where the parcel is matched to the certified roll) and will differ from the actual assessed bill. Cost and market figures are derived from available data and simple calculations, not a professional appraisal. We make no representation that any estimate reflects fair market value.
