ZIP and county figures describe the wider market, not Deer Run Unit 12B specifically. Momentum Research analysis of MLS records.

The build window from 1986 to 2016 is unusually long for such a small community, and the median build year of 1989 tells you most of the stock is on the older end. Practically, that means roofs, HVAC systems, and kitchens are the variables that separate one sale from the next. A home that has already tackled those items commands a very different number than one that has not, and the median living size of about 1,678 square feet gives you a useful anchor when comparing floor plans.

The high homestead share signals a neighborhood people stay in, which keeps listing counts low. That works in a seller's favor when a clean, updated home hits the market, but it also means buyers should not expect a wide menu of options at any given moment. Patience and readiness to act both matter here.

In a low-inventory pocket like this, the difference between a good outcome and a missed one is knowing when the right home is actually the right home. We track how condition, square footage, and updates move value inside Deer Run Unit 12B specifically, so we can tell you fast whether a listing is priced to its true condition or coasting on the neighborhood's scarcity.

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