The Messtimate
This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
Actual list price: $859,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 27% spread on the same house — and that gap is exactly what an automated guess can't see:
- Condition & finishes — as new construction, builder upgrades and finish level aren't in a sq ft number.
- The lot & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
- Outliers skew it — one flip or distressed sale in the comps drags the whole $/sq ft up or down.
- Carrying costs & concessions — this home carries HOA dues of $370/mo; with insurance and any seller-paid buydown, that changes what a buyer actually pays, and a sq ft estimate ignores all of it.
- The pool — a private pool carries cost and value that living area doesn't capture.
And here's what the live market is doing — which the number above ignores entirely:
- 2 active listings competing, 1 under contract
- ≈24.0 months of supply
- 1 closed here in the last 12 months
For reference, this home is listed at $859,000 ($491/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 7 SEBASTIAN Avenue #C, chosen from what the record shows. This is general guidance, not advice about this specific property.
- New construction: get the builder's warranty terms and the certificate of occupancy in writing, and ask which finishes shown are upgrades.
- HOA dues are listed at $370/mo: request the current budget, reserves, and rules before relying on that figure or on any restriction.
- FEMA flood zone AE: lenders generally require flood insurance here — get an elevation certificate and a flood quote before the inspection period ends.
- 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.
- Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
- Listed living area is 1,750 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 $7,387/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
- Confirm school zoning directly with the district.

Does 7 SEBASTIAN Avenue #C have an HOA, and how much are the dues?
