The Messtimate™

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.

$1,318,905the mess$1,678,355

Actual list price: $1,500,000 — 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 1934 home may have had its roof, kitchen, or HVAC replaced since, or not; sq ft can't see either.
  • 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:

  • 1126 active listings competing, 334 under contract

For reference, this home is listed at $1,500,000 ($542/sq ft) — a number set with analysis a Messtimate can't do.

Before you decide

Buyer research checklist

Items worth confirming for 105 21St Avenue, chosen from what the record shows. This is general guidance, not advice about this specific property.

  • Built in 1934 (92 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
  • 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.
  • Listed living area is 2,765 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 $15,750/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
  • School zoning shown here comes from district data and changes; confirm the assigned schools directly with the district before relying on them.

Frequently asked questions

How big is 105 21St Avenue and when was it built?

Per the listing record, 105 21St Avenue was built in 1934 and has 2,765 sq ft of living area, 5 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 105 21St Avenue in?

105 21St Avenue is in Phillips Div Rev Map in St Pete Beach, Pinellas County. The community section on this page shows recent closed sales, days on market, and active inventory for Phillips Div Rev Map from the same MLS data.

Does 105 21St 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 105 21St Avenue differ from the current owner's?

The estimate on this page (about $15,750 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 105 21St 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.
