Why investors buy South Side rentals

San Antonio's South Side has been quietly redeveloping for a decade. Brooks City Base, Texas A&M-San Antonio, the new Toyota North America and Continental supplier ecosystems, and the Mission Reach extension have all funneled investment south of Loop 410.

Entry prices remain under $200K for many SFRs and small multifamily, while rents have appreciated 35%+ over the past five years. The combination is the highest cap rate in San Antonio — but tenant management is more active here than on the Northwest Side, so we recommend South Side primarily to investors with existing portfolio experience or a strong local PM relationship.
