Thirtieth Ave is a community of 881 homes in St Petersburg, Pinellas County, built between 1916 and 2024 (median 1955), with a median living area of about 1,252 square feet. 72% of parcels are homesteaded, the owner-occupancy proxy in the Florida DOR assessment roll (2025 roll, public records).

Thirtieth Ave Sub Extention is an established, largely built-out St Petersburg community of roughly 881 homes in Pinellas County, weighted toward smaller mid-century structures with a meaningful layer of newer construction and rebuilds mixed in.

About 71.5% of homes here carry a homestead exemption, which tells you this is predominantly owner-occupied rather than an investor or rental-heavy area. That kind of ownership share tends to mean turnover is measured and homes are held rather than flipped, so inventory can be thin and each listing matters.

The building timeline is the story: a 1916-to-2024 range around a 1955 median means original mid-century homes sit next to teardown-and-rebuild activity. Expect variation in systems, footprints, and finishes block by block. Inspect carefully, budget for age where a home has not been updated, and treat recent construction as a separate segment of the same neighborhood.

In a market this condition-dependent, the average number tells you almost nothing about the house in front of you. We underwrite each property individually — vintage versus rebuild, deferred maintenance versus done work — so you are pricing to the specific home, not to a neighborhood median that spans more than a century of construction.

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