Folio's PropIQ™ score of 50 signals Caution conditions. Elevated price drops and longer days on market indicate softening in 78638.
The 78638 market displays contradictory signals with a median sale price of $441,000 and an extraordinary year-over-year increase of 215.0%, yet fundamental liquidity metrics suggest significant friction. Properties average 155 days on market, more than triple the typical hot market benchmark of 30-45 days. Zero homes are selling above list price, indicating buyers hold negotiating leverage despite the dramatic annual appreciation figure. This disconnect between price momentum and transaction velocity warrants careful examination of underlying demand drivers.
Patient buyers with flexible timelines benefit most from current conditions, as the extended 155-day marketing period and absence of bidding competition create room for negotiation below asking price. Sellers who purchased before the 215.0% surge can still extract substantial equity, though they must price realistically given the 0% above-list close rate. Investors seeking cash-flowing properties should scrutinize whether recent appreciation reflects sustainable demand or statistical anomaly from low comparable volumes. This is not a market for buyers requiring quick occupancy or sellers needing rapid liquidity.
The PropIQ score of 50/100 signals caution rather than avoidance, suggesting elevated risk without confirming imminent correction. Monitor monthly inventory levels and days-on-market trends—if DOM extends beyond 180 days or listings accumulate, the 215.0% gain may prove unsustainable. The current seller's advantage in price exists simultaneously with a buyer's advantage in negotiation time, a tension that typically resolves through either demand acceleration or price moderation within two quarters.
