Market Heat
Swallowfork Estates spans a wide build range, from the mid-1970s through 2024, with the median home dating to 2003. That spread is the single biggest driver of price here: condition, updates, and vintage matter more than any headline number. At a median of $320,750 and roughly $193 per square foot on about 1,825 square feet, this is a market where the difference between an original-condition older home and an updated or newer one shows up directly in the sale price.
The market posture is balanced. A heat score of 50 and a median of about 25 days on market tell you homes that are priced right move at a steady clip, without the frenzy or the stalling you see at the extremes. Sellers should price to condition rather than to the top comp; buyers have time to inspect and negotiate but not to sit on a well-priced listing. Values are up 6.2% year over year, so neither side is dealing with a falling market.

What the spread is telling you
With a build range of 1975 to 2024 and a median year built of 2003, Swallowfork Estates is not a uniform subdivision where every house trades in a narrow band. The median price of $320,750 is a midpoint across genuinely different products: dated original homes on one end, updated and newer builds on the other. Read the median as a starting reference, not a value for any specific home, and let condition and vintage do the rest of the work.
The 69% homestead share is worth weighing. A high owner-occupancy rate tends to correlate with steadier turnover and homes that have been lived in and maintained rather than flipped. It also means inventory can be thinner, since owners here lean toward holding. For a buyer, that puts a premium on being ready to move when the right condition-and-price match appears.
Why work with Momentum here
In a community where price is driven by condition and vintage more than by any single number, our value is in reading the individual home against the median, not selling you the median. We help sellers price to what their home actually is, and we help buyers see past a fresh coat of paint to what a 1975 versus a 2024 build really means for cost of ownership. On a roughly 25-day market, that judgment is the difference between a clean deal and an overpay.
