With a 15.7% vacancy rate in early 2026, the city outpaces even Austin, Houston and Dallas-Fort Worth
San Antonio currently holds the highest apartment vacancy rate among the 50 largest apartment markets in the United States — and for REALTORS and brokers working with investor clients, the number demands attention.
According to recent market data, the local apartment market posted a 15.7% vacancy rate in the first quarter of 2026, edging out Memphis, Tenn. (15.6%), Austin (14%) and Houston (12.7%) for the top spot. At the opposite end of the spectrum, New York City recorded the nation’s lowest vacancy rate at 3.1%.
The ranking is the product of a supply surge that began in the early 2020s, when low interest rates and strong in-migration fueled an apartment construction boom across Texas. Developers responded to demand signals that, at the time, pointed in one direction: build. San Antonio was no exception. Thousands of new units came to market in rapid succession, and absorption — while steady — never quite kept pace with delivery.
The city’s trajectory mirrors what Austin experienced in the preceding years. Austin held the top vacancy ranking nationally for several consecutive quarters following its own development wave, but its rate began declining in early 2025 as new supply slowed and renters worked through available inventory. San Antonio’s rate, meanwhile, kept climbing — eventually surpassing every other major market in the country, including former front-runner Memphis.
Relief appears to be on the horizon, and that is where the opportunity lies. New apartment starts dropped sharply in 2024, signaling that the pipeline is thinning. As construction slows and existing inventory is absorbed, analysts project vacancy rates will ease and rents will stabilize — setting the stage for appreciation in assets acquired at today’s compressed prices.
For brokers advising investor clients, the current environment rewards those who do their homework. Multifamily properties face margin pressure from multiple directions: elevated vacancies, concessions such as free rent and reduced deposits, and rising ownership costs driven by property taxes and insurance. Cap rates in San Antonio remain higher than in many comparable markets, however — making well-selected assets an attractive long-term play for buyers with patience and access to capital.
The single-family rental segment presents a cleaner near-term picture. Demand has remained more resilient, inventory tighter and occupancy steadier — giving investor clients in that space more immediate cash flow stability.
The bottom line for REALTORS: San Antonio’s multifamily market is at or near its cyclical low. Clients who understand that dynamic — and act accordingly — may look back on this window as one of the better buying opportunities the market has offered in years.
