San Diego House Prices Soar While Units Stall: What the Divergence Means for Buyers

San Diego’s red-hot housing market just delivered another notable twist: single-family home prices continued their upward march in June, outpacing condos and townhomes by the biggest margin in nearly a decade, according to data released Wednesday by the Greater San Diego Association of Realtors. The median price for a detached house in the county now stands at $1,172,000—an all-time high and up 8.2% from June last year—while attached units, like condos and townhouses, are up only 3.1%, with the median price at $703,000.

This growing price gap is more than a curiosity for real estate agents and economists—it speaks to shifting buyer preferences and how the layering of affordability pressures, investor interest, and changing local demographics are amplifying market segmentation. For potential homebuyers across the county, the house/unit split is shaping not only what they can afford, but also which neighborhoods feel within reach.

La Jolla to Mission Valley: A Tale of Two Markets

On streets like Caminito Mendiola in Mission Valley and down the bluffs of La Jolla Shores Drive, buyers say the gulf is highly visible. The San Diego Housing Commission reports persistent low inventory in established family enclaves, particularly in areas like Carmel Valley and Del Mar Heights, where detached home turnover is below two percent this year. Meanwhile, new mid-rise condo developments are being approved at record pace in Grantville and along Friars Road. Some buildings in East Village have gone months without seeing an increase in average listing price, held in check by a surge in units coming to market and a subtle but steady rise in days on market, now averaging 35 days compared to just 23 last summer.

“Houses west of I-5 are selling in less than two weeks, often with multiple offers,” said a Pacific Beach property manager, who handles both condos and detached listings, “but we’re seeing condo clients asking for price reductions or seller credits in Downtown and University City.”

Numbers Reveal Shifting Priorities

The numbers are stark. According to CoreLogic’s June Residential Price Index, detached homes in San Diego County have appreciated 40% since 2021, while attached properties are up just 26%. Mira Mesa and Clairemont, long considered accessible entry points for families, now have few single-family listings below $900,000. By contrast, 32% of active condo listings on Redfin last week were priced under $650,000, suggesting inventory remains less squeezed for buyers open to denser living. Local mortgage brokerages, including Guild Mortgage on Miramar Road, report a surge in clients weighing trade-offs between space and price as detached inventory drops to a new low of just 1.4 months’ supply.

Part of the divergence comes down to supply, say analysts. New construction of traditional family houses is barely keeping pace with population growth, constrained by zoning rules and a lack of buildable lots. In contrast, new attached units continue to rise, especially near transit corridors and college campuses. Remote work trends have also pushed more high-earning buyers to bid aggressively for houses with yards, parking, and home offices—a trend not lost on sellers in neighborhoods like Rancho Bernardo and Kensington, where listings are snapped up after single open houses.

Making Sense of the Split

The price divergence is unlikely to correct overnight. With single-family homes increasingly scarce, buyers seeking space or a foothold in competitive school districts face a premium. First-time buyers and investors may find more opportunity—and bargaining power—in the condo market, particularly in Hillcrest, Little Italy and parts of Chula Vista. Real estate advisors at the San Diego County Credit Union suggest would-be homeowners carefully assess monthly HOA fees and resale value trends, which can vary sharply by building and ZIP code.

For now, the best advice? House hunters should stay flexible on neighborhood and property type, secure pre-approval before tours, and keep an eye on city council debates over density incentives in the College Area and Linda Vista that could accelerate new attached supply. The split between house and unit prices is a useful reminder: in today’s market, what you buy—and where—really does matter for your balance sheet.
