Lakefront Living: Price Surge in Elmendorf Draws Investors to San Antonio’s Southern Shores

Home prices around Calaveras Lake in Elmendorf are up nearly 14% in the past year, cementing the southern suburb’s status as San Antonio’s hottest waterfront zone for both investors and families seeking open space and lake access.

That momentum has caught the attention of everyone from first-time buyers to major developers. As downtown San Antonio tightens and median prices edge toward $380,000, deep-pocketed buyers have increasingly looked beyond the 410 loop. Properties hugging the Calaveras Lake shoreline and West Loop 1604 S now command bidding wars—hardly a feature of Elmendorf just three years ago.

Calaveras Lake: From Quiet Retreat to Booming Market

Elmendorf sits 17 miles south of downtown, where the Medinas and Mission Trails region meets the urban fringe. Its big draw is the sprawling Calaveras Lake, a weekend fixture for boating and fishing locals for more than 50 years. Until recently, the area’s property scene was dominated by modest single-family ranches and fishing cabins on roads like Stuart Road and Lagarto Drive. The transformation began when infrastructure upgrades funded by the San Antonio River Authority opened up new parcels for development.

Developments like the gated Palomino Estates community (off Stewart Road) now offer waterfront custom builds listed above $600,000—the first time the zip code has seen sustained six-figure listings over $500,000. Local realtor Diego Ruiz of Ruiz Realty says around a third of this year’s sales are going to out-of-town investors, many from Houston and Dallas, drawn by projected returns after a run of consecutive double-digit price growth. The Calaveras Park & Community Club, long just a quiet boat launch and picnic area, has seen attendance double in summer 2026, according to Bexar County Parks data. There’s new buzz at old mainstays like La Pasadita Mexican Café, and weekends bring lines at the lake pier.

Price Data and Buyer Trends

Bexar County Appraisal District’s April 2026 figures peg Calaveras Lake waterfront home values at an average of $331 per square foot, up from $289 last summer. Available three-bed lakefront homes are now rarely listed below $465,000, a sharp contrast to typical figures from 2022, when similar properties averaged just $285,000. The competitive streak shows up in year-to-date transaction numbers: Redfin’s local dashboard tracked 61 lakefront home sales so far in 2026, up 40% over the same period last year. The majority of new listings along South Foster Road and Stuart Road spend less than 12 days on the market—substantially less than the metro average of 31 days.

Local builders like L&B Custom Homes have begun acquiring acreages closer to the lake’s southern shore after the city’s May 2025 expansion of sewer and water service, making year-round habitation more practical. Neighborhood groups have lobbied city council for stricter short-term rental regulations, fearing an erosion of the tight-knit community as STRs proliferate along the lake. Meanwhile, public works projects such as the ongoing cycle path upgrade connecting Elmendorf Park to Calaveras Lake are expected to finish by spring 2027, improving accessibility further.

For buyers, the outlook is bullish but nuanced. Inventory is tight, and waterfront supply in Elmendorf is unlikely to spike soon—even as demand ticks up. Potential investors should act decisively, securing financing and working with area-knowledgeable agents familiar with lakefront permitting and flood zone compliance. Watch for updates from both the Bexar County Planning Office and the San Antonio River Authority, especially on environmental protections and any coming changes to shoreline development rules. These factors will determine whether this lakeside boom maintains pace—or finds its level.
