2 UNIT PROPERTY WITH GARAGE!!! PAID OFF SOLAR, NEW HVAC SYSTEMS, NEW WINDOWS & TRUE 2-UNIT PROPERTY on over 0.25 acres with sweeping views of Downtown San Diego and Mt. Helix. Located on a crest-line street in the desirable Spring Valley neighborhood, this one-of-a-kind mid-century property features two fully functional units: a spacious 4 bed, 2 bath main residence and a massive, fully independent 1 bed, 1 bath guest house (approx. 640 sq ft, built in 1995) with vaulted ceilings, creating an open and airy feel. Ideal for multi-generational living, rental income, or house hacking. The main home showcases panoramic corner-to-corner view windows in the living room, flooding the space with natural light and capturing stunning views. Recent upgrades include brand new stainless steel appliances (dishwasher, range, hood), restored and gloss-coated hardwood floors, and new wood-like LVP flooring throughout the dining and living areas. The guest unit offers excellent income potential and is complemented by a detached 2-car garage, providing additional opportunity for conversion or added value (buyer to verify). The expansive lot offers significant upside—build additional units, add a workshop, or create a private compound. The current owners have successfully operated a dog boarding business from the property, generating additional monthly income. Conveniently located near shopping, dining, and freeway access, this is a rare opportunity combining upgraded systems, income potential, and future development upside all in one.
