Momentum Property Score
63/100 is solid, mid-pack across the objective indicators below. It reflects only those measures — not the home’s quality, condition, or desirability.
A 0-100 score built from objective property and market data: flood risk, insurance, pricing, supply, affordability, and recent sales. Higher means more measures line up in a buyer’s favor. It reflects only the factors below.
Momentum Scores are objective, rules-based indicators computed from listing facts, public records, and recent nearby sales. They are not appraisals, valuations, investment advice, or judgments about a neighborhood or who should live there. Verify independently.

Data is deemed reliable but is not guaranteed by the MLS to be accurate.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: $999,000 — 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 & updates — a renovated kitchen or new roof vs. dated finishes can swing value six figures; sq ft can't see it.
- 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 — CDD, HOA, insurance, and seller-paid buydowns change what a buyer actually pays.
And here's what the live market is doing — which the number above ignores entirely:
- 60 active listings competing, 15 under contract
For reference, this home is listed at $999,000 ($470/sq ft) — a number set with analysis a Messtimate can't do.

Frequently asked questions
Why might my property taxes differ from the current owner's?
Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment can be re-set after a sale. As a result a new owner's bill may differ from the seller's. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Where does the flood-zone information come from?
The flood designation shown (Zone X) comes from the FEMA flood map and is provided for general information. 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.
