Why It May Not Have Sold

This property was listed at $2,299,000 and withdrawn after 90 days on market. This listing activity factors into the valuation.

This home was listed at $2,299,000 and was on the market for 90 days before being withdrawn. Based on comparable sales, the market data suggests a value closer to $2,191,679. Here are some factors that may have played a role: The listing had a price reduction during its time on market, which can sometimes affect buyer perception. At $652/sqft, the asking price was 139% above the area median, though there may have been upgrades or features not captured in the data. This home's smaller footprint (242 sqft vs the comp average) plays a role in how the market prices it. The pool is a standout feature, with 4 of 7 comparable homes not offering one. Based on 7 relevant data points in APPALOOSA RUN, I'm comfortable with this estimate. Without stepping inside, I can only go by what the data shows. An in person look would tell the full story.
