About This Home

Unique Investment Opportunity in Twin Oaks Valley - only 10 miles inland. 4 contiguous parcels with 2 detached houses and 800 sf shed on 8.67 acres, including private road. Two houses: 515B, and 515A - appraised in October 2023 for a combined value of $2.2M! Appraisal did NOT include the 2 additional parcels. APNs 182-280-13, -14, -15, and 182-240-25. R-2 zoning. Unincorporated San Marcos - San Diego County jurisdiction. 515B was built in 1982, and currently has 4 bedrooms, 3 baths, plus a studio, with an attached 2 car garage. 515A was built in 1947, and currently has 4 bedrooms and 2 baths. Both houses and the shed have separate electric meters, and there is one 2 inch water meter at the shed. This is an opportunity for a builder to create a compound, or develop multiple properties. County zoning allows for ADU and detached workshops. Fantastic location: easy freeway access, both the 78 and 15 are less than 10 minutes away. Only 4 miles to Cal State San Marcos and Palomar College. Rare chance to build in Twin Oaks Valley!
