Why San Diego Sellers Are Choosing Cash Buyers

Nearly 4 million American homes now house multiple generations, up from 3.2 million in 2014, creating sustained demand through 2026 and beyond. In San Diego's competitive neighborhoods—Pacific Beach, North Park, La Jolla, and Hillcrest—multi-gen properties are moving quickly.

These listings received 13.5% more page views than standard homes while selling in the same median 59-day timeframe, signaling strong buyer interest despite premium pricing. For sellers with multi-gen properties in San Diego County, cash offers eliminate financing contingencies and accelerate closings on high-value assets.

In North Park alone, 117 ADU permits were issued over the past 12 months, with properties featuring separate living quarters or existing ADUs trading at the top of the $1.125M median single-family price range. Coastal neighborhoods like Pacific Beach command $2,500-$3,500 monthly for one-bedroom ADU rentals, adding investment appeal.

Market Drivers: Affordability and Demographics

According to the 2025 Home Buyers and Sellers Generational Trends Report, 17% of homebuyers purchased multi-generational homes in 2025—a record for the segment. The breakdown: 21% of Gen X buyers (ages 45-59), 15% of younger boomers (ages 60-69), and 12% of older millennials (ages 35-44).

Cost savings drove 36% of 2024 multi-gen buyers, reflecting affordability pressures across San Diego County. With the median price per square foot at $686 in mid-2026, standard single-family homes are increasingly out of reach for single-generation households.

New ADU laws allow property owners to build up to 5 accessory units on single-family lots, with Senate Bill 1077 requiring coastal zone ADU guidance by July 1, 2026. This regulatory shift opens conversion opportunities for cash buyers targeting standard homes in Pacific Beach, La Jolla, and other coastal communities.
