Price & listing history
Building permits
Comparable recent sales
6 closed sales within about 3 miles in the last 18 months — same property type, living area within 30% of this home. Sold prices are MLS closed-sale records, deemed reliable but not guaranteed.
Median of these 6 sales: $487,350 ($282/sq ft). Stronger local evidence. Shown for general reference only — not an appraisal or a statement of this home’s value.
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.
Stronger local evidence — 6 comparable closed sales within about 3 miles, closed within the last 18 months, same property type, living area within 30% of this home.
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 49% 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 — the band above comes from 6 nearby sales; one flip or distressed sale moves the whole $/sq ft.
- 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). The list price is the seller's asking price and is not derived from this range.

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.

- 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 current bill is not a guide Exemptions and portability change the actual bill — confirm with the county property appraiser.

Frequently asked questions
How big is 530 79Th Street and when was it built?
Per the listing record, 530 79Th Street was built in 1959 and has 1,718 sq ft of living area, 3 bedrooms and 2.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 530 79Th Street in?
530 79Th Street is in South Cswy Isle 4Th Add in St Petersburg, Pinellas County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 530 79Th Street 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 530 79Th Street differ from the current owner's?
The estimate on this page (about $13,114 per year) assumes reassessment at the list price less the homestead exemption. Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 530 79Th Street 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.
