Property taxes
✓ Certified county tax rollProperty 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.
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.
Certified 2025 tax roll values for this parcel (Florida DOR). The roll gives values, not the bill; the current owner’s bill above is estimated from the taxable value.

County public record, not MLS data — matched to this home by parcel ID. Estimates are not a tax bill; the county property appraiser and tax collector set the actual amount.
What it really costs to own 353 Red Barn Road
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 $6,175/yr (certified county roll, taxable value × millage). Buy at the asking price of $640,000 and the first-year bill resets to about $7,950/yr (the parcel is matched to the certified roll; asking price less the $50,000 homestead exemption × 13.47 mills); Save Our Homes caps later increases at 3%/yr. |
|---|---|
| HOA dues | $7/month per the listing record. Dues cover what the association documents say they cover; ask for the budget and reserve study before you close. |
| Home and flood insurance | The average Citizens Property Insurance premium in Saint Johns County is $1,378/yr (977 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 $1,500–$3,000/yr; neither is a quote. |
| Roof and age | Built in 2023. A newer roof and current wind-mitigation features usually mean the lower end of insurance quotes; ask for the wind-mitigation form. |
Estimated carrying cost at the asking price, before the mortgage: about $784/month (tax $662, HOA $7, insurance $115). An estimate from the sources above, not a quote; the monthly-cost calculator on this page adds the loan.

Sourced environmental data for the parcel. Confirm with FEMA and your insurer.
Not yet verified for this address. Look up the parcel at msc.fema.gov before relying on any flood assumption.

St. Johns County is on the Florida coast; wind coverage is a major part of the premium. Premiums and coverage vary by home (roof age, wind mitigation, claims history); obtain a quote from a licensed insurer.

Buyer research checklist
Items worth confirming for 353 RED BARN Road, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 2023: confirm the roof and HVAC install dates and whether any builder or manufacturer warranty transfers.
- HOA dues are listed at $7/mo: request the current budget, reserves, and rules before relying on that figure or on any restriction.
- 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 St. Johns 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.
- Listed living area is 3,252 sq ft: verify it against the property appraiser's record and measure before relying on it.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $7,950/yr) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $1,775 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.

How big is 353 RED BARN Road and when was it built?
Per the listing record, 353 RED BARN Road was built in 2023 and has 3,252 sq ft of living area, 5 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 353 RED BARN Road in?
353 RED BARN Road is in Grand Oaks in St. Augustine, St. Johns County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 353 RED BARN Road have an HOA, and how much are the dues?
The listing reports HOA dues of $7 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
Why might property taxes on 353 RED BARN Road differ from the current owner's?
The estimate on this page (about $7,950 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $1,775 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 353 RED BARN Road 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.
