Folio Market Intelligence Report · 37866AI ANALYSIS

The 37866 ZIP code shows a median sale price of $534,000 as of February 2025, representing a substantial 24.7% year-over-year increase that outpaces broader Knoxville market trends. However, homes are taking an average of 177.5 days to sell, nearly six months of market time that signals buyer hesitation at current price levels. Only 25% of properties are commanding above-list offers, indicating limited competition despite the double-digit appreciation rate.

This environment favors patient sellers with equity positions who can afford extended marketing periods to capture premium pricing. The 177.5-day absorption rate creates risk for buyers stretching budgets, as they face both elevated entry costs and potential liquidity constraints on resale. Investors should avoid this ZIP unless targeting long-term holds, since the combination of rapid appreciation and slow turnover suggests price discovery is incomplete and downside protection is minimal.

The PropIQ score of 66 signals caution rather than opportunity, reflecting the tension between aggressive price growth and weakening velocity metrics. The critical indicator to monitor is whether days-on-market extends beyond 200, which would confirm buyer resistance to current valuations and likely trigger price corrections. The 24.7% appreciation rate appears unsustainable given market friction, suggesting either a slowdown in price growth or increased inventory absorption time through 2025.
