The single most useful number in this snapshot is the year-built spread. A 1922-to-2024 range inside one community means original construction, decades of remodels, and new infill are all sitting side by side. That is common in older Pinellas County neighborhoods that get built out in waves — first the original lots, then teardown-and-rebuild or major renovation on a smaller share of parcels over time. For a buyer, it means the listing description and a recent-permit check matter more here than in a subdivision built in a single year.

At a median of 1,487 square feet, most homes here are modest in scale rather than sprawling — this reads as a market of efficient, right-sized houses rather than large-lot statement homes. No community amenities are identified in current MLS listings, so whatever draws buyers to this pocket is the location and the housing stock itself, not a clubhouse, pool, or gated entry. That is worth knowing going in: if a buyer is shopping for amenity-driven living, this is not that community.

In a market with this much variation in age and condition, comparable sales are only a starting point — we walk the property, check what has actually been updated versus what has aged in place, and price against the real condition rather than the address. That is the difference between guessing and knowing what you are bidding on in a neighborhood like this one.

Confirm the current HOA dues, exactly what they cover, and any CDD bond or special assessment for a specific address before you offer.
