Rare opportunity to own a true duplex in San Marcos. Each unit features 3 bedrooms, 2 bathrooms, approximately 1,146 square feet, private laundry, a 2-car garage, and a large backyard. The property sits on an oversized 14,761-square-foot (.34-acre) lot, giving both units plenty of outdoor space. The property does have deferred maintenance and will need updating, but it offers a great opportunity for an investor or owner-occupant looking for a property they can improve over time. With two spacious 3-bedroom units, separate garages, private yards, and a large lot, there is a lot to work with here. The location is another big plus. Palomar College and Cal State San Marcos are both nearby, along with the Sprinter, San Marcos Civic Center, shopping, restaurants, and everyday conveniences. Highways 78 and 15 are also easily accessible, making it convenient for commuters throughout North County and San Diego. Duplexes in San Marcos don't come on the market very often, especially with this combination of unit size, garages, yard space, and lot size. This is a solid opportunity for a buyer looking to add value and own a two-unit property in a convenient San Marcos location.
