3691 National Ave is a 22 unit multifamily property located on the corner of National and 37th St in San Diego's "Southcrest" neighborhood. Unique for San Diego, the property was built in 1990. It was originally a 15 unit complex that now has had seven brand new ADU's, with certificate of occupancy available. Due to the vintage and current condition, electrical/insurance/plumbing should not be problematic for any new owner. With strong in place rent and fundamentals currently, 3691 National will have low maintenance costs for the foreseeable future. The unit mix consists of twenty-one 1 bed/1 bath units and one studio. Ideally located between I-5 & I-805, the gated complex features nine garages as well as additional 11 off-street parking spaces for the tenants to utilize along with laundry on site.
