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: $2,495,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 14% 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 — the band above comes from 6 nearby sales; one flip or distressed sale moves the whole $/sq ft.
- Carrying costs & concessions — this home carries HOA dues of $1,555/mo; with insurance and any seller-paid buydown, that changes what a buyer actually pays, and a sq ft estimate ignores all of it.
And here's what the live market is doing — which the number above ignores entirely:
- 4 active listings competing, 1 under contract
- ≈3.7 months of supply
- 13 closed here in the last 12 months
For reference, this home is listed at $2,495,000 ($1,346/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 100 1St Avenue #1603, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 2018: confirm the roof and HVAC install dates and whether any builder or manufacturer warranty transfers.
- Condominium: request the association's budget, reserves, the most recent milestone or structural inspection report, and two years of meeting minutes before relying on the dues.
- 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 Pinellas County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Listed living area is 1,854 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 $26,198/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.
