Property taxes
✓ Certified tax roll · county-average rateProperty 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.
The current owner’s taxable value is below today’s asking price; after a sale the assessment is set from market value, so the estimated bill is higher. Exemptions and portability can reduce it.

Buyer research checklist
Items worth confirming for 9815 W Us Highway 98 ## A505, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1985 (41 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
- Condominium: request the association's budget, reserves, the most recent milestone or structural inspection report, and two years of meeting minutes before relying on the dues.
- Look up the parcel on FEMA's Flood Map Service Center and confirm with your insurer whether flood insurance is required.
- Get a homeowners insurance quote for this specific address in Walton 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 $8,275/yr) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $1,875 more per year than the current owner’s estimated bill (+29%). Exemptions and portability change the actual bill — confirm with the county property appraiser.
- School zoning shown here comes from district data and changes; confirm the assigned schools directly with the district before relying on them.

Frequently asked questions
How big is 9815 W Us Highway 98 ## A505 and when was it built?
Per the listing record, 9815 W Us Highway 98 ## A505 was built in 1985 and has 2 bedrooms and 2.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 9815 W Us Highway 98 ## A505 in?
9815 W Us Highway 98 ## A505 is in Hidden Dunes Gulfside 1 in Miramar 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 9815 W Us Highway 98 ## A505 differ from the current owner's?
The estimate on this page (about $8,275 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $1,875 more per year than the current owner’s estimated bill (+29%). 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 9815 W Us Highway 98 ## A505 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.
