Two doors down, $280k became $695k.
5509 15th Ave S, Gulfport 33707 · Active · September 9, 2026
5509 15th Ave S, Gulfport is asking $265,000: 2 bed, 1 bath, 1,064 sf, built 1944, on 0.14 acres. 0.03 miles away, 5518 Newton Ave S, Gulfport, Fl 33707 was bought for $280,000 in Jan 2025 and sold for $695,000 in Mar 2026, 435 days later: 2.48× on the recorded deeds. 1,791 sf against this one’s 1,064, so part of that resale was an addition. It has already come down $14k and has been on the market 80 days, which is where sellers start listening. I will not put a number on this one on a public page. I will put it in an email, with the closings behind it, if you ask.
Why this one could follow
- The receipt: 5518 Newton Ave S, Gulfport, Fl 33707 bought $280,000 (Jan 2025), sold $695,000 (Mar 2026), 435 days held, 2.48× — from the county record, 0.03 mi from this house.
- 80 days on market, one price cut already ($14k): this seller is negotiable.
- Flood zone X: outside the special flood hazard area, which keeps the insurance quote sane.
What I would check first
- The last three closings on this exact street, not the ZIP: I pull them from the record before any number gets written down.
- Whether the proven one grew: it resold at 1,791 sf against 1,064 here, so its price included an addition and the budget has to too.
- Roof, AC and electrical dates on the county permit record: they decide the budget more than the kitchen does.
- A written insurance quote before the offer, even in zone X.
