September 2025 San Diego Housing Market Update
San Diego home prices moved in opposite directions across property types in September. The median sale price for detached homes declined 2.8 percent year-over-year to $1,020,500, reflecting added inventory and longer marketing times for detached properties.
Attached homes, including condos and townhomes, saw prices move higher, with the median rising 3.2 percent to $671,500, supported by steady demand at lower price points.
Growing inventory continued to shape the fall market. Detached home listings increased 19.2 percent compared to last year, while attached inventory climbed 45.2 percent year-over-year. This expanded supply gives Buyers more room to evaluate options and negotiate, while Sellers are adjusting price strategies as days on market stretch and competition increases across many neighborhoods.
