Union Heights is an older St Petersburg pocket where the housing stock does most of the pricing work. With a median build year of 1958 and homes dating back to 1927, condition is the variable that moves value here — a renovated 1,300-square-foot bungalow and a deferred-maintenance shell can carry very different numbers. Expect a wide spread driven by what has and hasn't been updated, not by square footage alone. The median living area sits near 1,300 square feet, so this is a compact-home market at its core.
The homestead share is high at roughly 77%, which tells you most of these homes are held long-term rather than flipped or rented. That tends to keep resale inventory tight and lightly renovated stock scarce. For a buyer, patience and a willingness to take on projects will open more doors. For a seller with an updated home, thin comparable supply can work in your favor — but pricing has to be tied to condition, because the range is too wide to lean on a neighborhood average.

🟢 Buyer-leaning market. 12.0 months of supply and 0% of the inventory already under contract give buyers above-average negotiating leverage.Why it matters: months of supply is how long today's inventory would last at today's sales pace; under-contract share is the portion of homes for sale that already have a buyer.Momentum Research analysis of Stellar MLS records, as of September 20, 2026.

The Union Heights buying strategy.
If we were buying in Union Heights today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Use your leverage. With inventory sitting, there is room to negotiate on anything dated or overpriced and to ask for repairs or a rate buydown.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Union Heights.
An older, compact housing stock
The defining feature of Union Heights is age. A median build year of 1958 and a floor of 1927 mean original systems, older layouts, and character are common, and the value gap between a maintained or renovated home and one needing work is the main thing to underwrite. The scattering of newer construction — the range runs to 2022 — shows some infill activity, but it is the exception, not the pattern.
Sizes stay modest, with a median around 1,308 square feet. That points to bungalows and smaller single-story homes rather than large floor plans. Buyers who want space will need to look hard or plan to add on; buyers who want a manageable footprint in an established St Petersburg neighborhood have a real match here.
The location and the amenities are priced into every listing in Union Heights. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a market this condition-driven, a neighborhood average tells you almost nothing about a specific house. We price and evaluate Union Heights homes on what's actually behind the walls — roof, systems, updates versus deferred work — because with stock this old and inventory this tight, that's where the money is won or lost.
