⚠️
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 $12,125/yr ($1,010/mo) — taxable value $939,471 × 12.89 mills
$10,775 more each year
(+89%)
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.

What it really costs to own 521 Gulf Shore Drive
The parts of the monthly number a mortgage calculator leaves out, from this listing's MLS record, the county tax roll, Citizens and FEMA. Property facts only.
Property tax
The current owner's bill is about $12,125/yr (certified county roll, taxable value × millage). Buy at the asking price of $1,825,000 and the first-year bill resets to about $22,900/yr (the parcel is matched to the certified roll; asking price less the $50,000 homestead exemption × 12.89 mills (county-average millage, estimate)); Save Our Homes caps later increases at 3%/yr.
Home and flood insurance
The average Citizens Property Insurance premium in Okaloosa County is $2,644/yr (1,101 policies, Citizens detail by county, April 2026); private-market quotes differ by roof age, wind mitigation and distance to the coast. The page's modeled range for this home is $8,500–$17,000/yr; neither is a quote. Flood: this address maps to FEMA zone X, outside the high-risk zone; flood insurance is optional but most lenders and insurers recommend it. Statewide, a zone X flood policy runs about $500–$700/yr (FEMA Risk Rating 2.0 averages, not a quote).
Roof and age
Built in 1972. An original roof would be about 54 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report and ask for the roof permit date.

Oct 2026 · Parks Amenities
Okaloosa and Cinco Bayou open upgraded boat ramp with new trailer parking
Okaloosa County and the Town of Cinco Bayou held a ribbon cutting for upgraded boat ramp facilities, including 16 new boat trailer parking spaces, a new restroom and landscaping. The $4.1 million total, funded largely by tourism development funds, also covers the $2.95 million purchase of a former bank building at 198 Eglin Parkway NE. Future dock improvements are planned.
Why it matters: Added trailer parking and ramp access improve waterfront recreation access for Fort Walton Beach area boaters. The project is about 6 miles west of Holiday Isle, elsewhere in Okaloosa County.
Okaloosa commissioners reject 12-month data center moratorium 3-2
Okaloosa County commissioners voted 3-2 on September 15 against a 12-month data center moratorium. On September 3 the board unanimously directed staff to develop a regulatory framework for data centers, with an outline due within 60 days. No specific project or site was proposed, and commissioners discussed protecting the Shoal River Industrial Park.
Why it matters: The pending rules will shape where large power-and-land-intensive facilities can locate in the county, including industrial land near Crestview. The project is about 24 miles north of Holiday Isle, elsewhere in Okaloosa County.
Destin and Okaloosa County agree on management of 4-acre Holiday Isle state park
Destin and Okaloosa County unanimously agreed to back Destin as manager and developer of the roughly four-acre state-acquired park on Holiday Isle near Norriego Point. In return, Destin council voted 5-2 to offer free parking to all Okaloosa County residents at city-owned lots and parks. The deal still requires state Board of Trustees and DEP review.
Why it matters: Management of the Holiday Isle park and city parking rules will affect public waterfront access and parking in Destin. The site is about 1 mile south of Holiday Isle.
DeSantis signs state budget with funding for Okaloosa County projects
Governor DeSantis signed the state budget that included roughly $15 million for 20 Okaloosa County projects, among them $5 million for the Northwest Florida State College Workforce Innovation Center in Niceville, $1.5 million for Shalimar Bridge Park, and $3 million for Destin road and drainage work. About $7.26 million in other local requests were vetoed.
Why it matters: Directs state funding toward workforce, park, road, and drainage infrastructure across Okaloosa County, supporting public facilities and capacity in Niceville, Shalimar, and Destin. The site is about 8 miles north of Holiday Isle.

Items worth confirming for 521 Gulf Shore Drive, chosen from what the record shows. This is general guidance, not advice about this specific property.
Built in 1972 (54 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
Confirm whether a mandatory HOA applies to this parcel and what it charges.
FEMA flood zone X: flood insurance is not usually required, but get a quote anyway — FEMA reports roughly one in four flood claims come from outside high-risk zones.
Get a homeowners insurance quote for this specific address in Okaloosa County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
Confirm square footage and room dimensions independently.
Order a survey to confirm lot boundaries and easements.
Review permit history with the county.
Property taxes: the estimate on this page (about $22,900/yr) assumes reassessment at the list price less the homestead exemption.

Frequently asked questions
How big is 521 Gulf Shore Drive and when was it built?
Per the listing record, 521 Gulf Shore Drive was built in 1972 and has 5 bedrooms and 3.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 521 Gulf Shore Drive in?
521 Gulf Shore Drive is in Holiday Isle in Destin, Okaloosa 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 521 Gulf Shore Drive differ from the current owner's?
The estimate on this page (about $22,900 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $10,775 more per year than the current owner’s estimated bill (+89%). 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 521 Gulf Shore Drive in a flood zone?
The FEMA flood map places this parcel in Zone X, outside the special flood hazard area, so flood insurance is not usually required by a lender. It is still available and worth quoting; confirm the parcel's status with FEMA and 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.
