The Messtimate
Insufficient local evidence for an automated estimate. The Messtimate is a deliberately simple range — living area × recent closed-sale $/sq ft from comparable homes nearby — and it only renders when at least 3 defensible sales exist within about 10 miles in St. Johns County in the last 18 months. None qualify for this home, so no dollar range is shown. It is not an appraisal or a valuation.
Methodology: the range would be 2,132 sq ft × the interquartile $/sq ft of comparable closed sales (same property type, living area within 30%, closed within 18 months, nearest verified subdivision, 3-mile, then 10-mile same-county stage). Estimate for general information only; never an appraisal, valuation, or offer. Updated September 30, 2026.

- HOA dues are listed at $211/mo: request the current budget, reserves, and rules before relying on that figure or on any restriction.
- A CDD assessment of about $1,900/yr is on record: confirm the bond balance and remaining term with the district; it appears on the tax bill.
- Look up the parcel on FEMA's Flood Map Service Center and confirm with your insurer whether flood insurance is required.

- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.

Frequently asked questions
How big is 51 MISSION Drive and when was it built?
Per the listing record, 51 MISSION Drive was built in 2026 and has 2,132 sq ft of living area, 2 bedrooms and 2.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 51 MISSION Drive in?
51 MISSION Drive is in Watersong At Rivertown in St. Johns, St. Johns 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.
Does 51 MISSION Drive have an HOA, and how much are the dues?
The listing reports HOA dues of $211 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
What is a CDD fee?
A Community Development District fee funds a community's roads, amenities, and infrastructure through a bond and appears on the annual tax bill. This parcel shows a CDD assessment of about $1,900 per year; confirm the exact figure with the county.
Why might property taxes on 51 MISSION Drive differ from the current owner's?
The estimate on this page (about $5,065 per year) assumes reassessment at the list price less the homestead exemption. 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.
Are short-term rentals allowed at 51 MISSION Drive?
Many communities restrict short-term rentals, and city/county rules also apply. Confirm the current HOA/CDD rules and local ordinances directly before assuming any rental use.
Is 51 MISSION Drive 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.
