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: $1,249,000 — 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 1959 home may have had its roof, kitchen, or HVAC replaced since, or not; sq ft can't see either.
- 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.
- 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:
- 5 active listings competing
- ≈30.0 months of supply
- 2 closed here in the last 12 months
For reference, this home is listed at $1,249,000 ($727/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 530 79Th Street, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1959 (67 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.
- Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
- Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
- Listed living area is 1,718 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 $13,114/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.

What community is 530 79Th Street in?
530 79Th Street is in South Cswy Isle 4Th Add in St Petersburg, Pinellas County. The community section on this page shows recent closed sales, days on market, and active inventory for South Cswy Isle 4Th Add from the same MLS data.
Does 530 79Th Street have an HOA?
