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: $2,149,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 28% 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 — this listing is waterfront; water frontage is priced far off a per-sq-ft average of the neighborhood.
- 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:
- This home: 78 days on market vs. a 104-day community median
- 4 active listings competing, 1 under contract
- ≈3.2 months of supply
- 15 closed here in the last 12 months
For reference, this home is listed at $2,149,000 ($585/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 220 90Th Avenue, 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.
- The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
- 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 Pinellas 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 3,673 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 $22,564/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.

Per the listing record, 220 90Th Avenue was built in 2026 and has 3,673 sq ft of living area, 4 bedrooms and 4.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 220 90Th Avenue in?
220 90Th Avenue is in Sun Plaza Isles in St Petersburg, Pinellas County. The community section on this page shows recent closed sales, days on market, and active inventory for Sun Plaza Isles from the same MLS data.
Does 220 90Th Avenue have an HOA?
The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.
Why might property taxes on 220 90Th Avenue differ from the current owner's?
The estimate on this page (about $22,564 per year) assumes reassessment at the list price. Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment resets after a sale, so 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.
Is 220 90Th Avenue in a flood zone?
The FEMA flood map places this parcel in Zone AE, a special flood hazard area where lenders generally require flood insurance on a mortgaged purchase. Confirm the parcel's status with FEMA and your insurer, and ask for an elevation certificate.
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.
