Assumable Mortgage in Rancho Santa Fe, CA
San Diego County is one of the few markets in California showing positive year-over-year price appreciation — up 0.8% to a median sale price of $899,250 — which speaks to the structural demand created by its combination of military employment, biotech and defense industries, and exceptional quality of life. Inventory remains constrained at 4,189 active listings for a county of over 3.2 million residents, and the 46-day median days on market is among the fastest we track across all five states we serve.
The 2025 conforming loan limit for San Diego County is $1,006,250, reflecting its designation as a high-cost area. This is a critical planning figure: buyers purchasing below that threshold can access conventional financing at standard rates, avoiding jumbo pricing. VA loans are the dominant financing vehicle in San Diego — we close more VA transactions here than in any other market outside of Bexar County, Texas — and the VA's no-down-payment benefit carries enormous purchasing power in this price environment.
San Diego's borrower mix is anchored by active-duty military and veterans, who account for a disproportionately high share of purchase transactions relative to the general population. Beyond the military community, we see tech and biotech professionals from Sorrento Valley and Torrey Pines, as well as a robust self-employed segment tied to the county's entrepreneurial base. Move-up buyers from Los Angeles represent a growing cohort seeking the relative affordability premium San Diego offers versus LA.
Use VA entitlement to its full advantage — no loan limit with full entitlement, and no PMI, delivers unmatched purchasing power in San Diego.
