3237 S Bonita Spring Valley, CA 91977

PAID OFF SOLAR, NEW HVAC SYSTEMS, NEW WINDOWS & TRUE 2-UNIT VALUE-ADD OPPORTUNITY on over 0.25 acres with panoramic views of Downtown San Diego and Mt. Helix. Located on a crest-line street in Spring Valley, this income-producing property features two fully independent units: a 4 bed, 2 bath main residence and a large 1 bed, 1 bath guest house (approx. 640 sq ft, built in 1995) with vaulted ceilings, ideal for maximizing rental income or multi-generational living. This property is primed for investors seeking strong in-place income with additional upside. The current ownership has successfully operated a dog boarding business on-site, creating an additional revenue stream beyond traditional rents. Major capital improvements have already been completed, including paid off solar, new HVAC systems, and new windows-significantly reducing operating expenses and increasing long-term efficiency. The oversized 0.25+ acre lot offers substantial development potential-add additional units, expand existing structures, convert the detached 2-car garage, or create a multi-unit compound (buyer to verify zoning and highest & best use). With strong rental flexibility, multiple income streams, and future development upside, this is a rare opportunity for investors, builders, or owner-occupants looking to scale their portfolio. Convenient access to freeways, shopping, and employment centers further enhances tenant demand and long-term appreciation potential.
