Alamo Heights vs Olmos Park vs Terrell Hills: The 78209 Veteran Buyer's Guide to San Antonio's Original Luxury Enclaves (2026)

Why Are There Three Cities Inside the 78209 ZIP Code?

Alamo Heights incorporated in 1922. Olmos Park followed in 1939. Terrell Hills was incorporated in 1957. By the time San Antonio's city limits had expanded north, the three small cities were already legally distinct, surrounded but never absorbed. They are what Texas calls "enclave cities."

The practical effect: when you buy in 78209 you are not buying "in San Antonio." You are buying in one of three independent municipalities with their own city councils, their own police departments, their own building codes, their own property-tax bills, and in some cases their own zoning. Your driver's license still says Texas. Your trash gets picked up by a different city.

This matters for buyers because the three enclaves price differently, regulate differently, and attract different buyers. Aggregator sites lump them together as "78209" and miss the distinction. A veteran moving into the area on military retirement, or a senior officer at JBSA-Randolph who wants the short commute up Broadway, needs to understand what the three enclaves actually offer.

What Is Alamo Heights and Who Should Buy There?

Alamo Heights is what most San Antonians mean when they say "the Heights." It runs from the Olmos Basin south to Hildebrand and east-west between Broadway and Devine. The housing stock is dominated by 1920s and 1930s Mediterranean Revival, Tudor, and Colonial Revival homes on lots of a quarter to half an acre. Newer construction has crept in along the edges, but the historic core is protected.

The school anchor is Alamo Heights ISD, a TEA "A" rated district with a single 7-12 secondary campus (Alamo Heights Junior School and Alamo Heights High School share a campus). Test scores rank with the top 5% of Texas public schools. Military families on PCS orders frequently identify AHISD as a primary reason to target the 78209 triangle.

The buyer profile in Alamo Heights skews physician, attorney, oil-and-gas professional, and retired senior military officer. The proximity to downtown San Antonio (15 minutes) and to JBSA-Randolph (about 12 miles east via Loop 410) makes it workable for officers commuting to a base assignment. The walkability to Broadway shops and restaurants is unmatched in the three enclaves.

What Is Olmos Park and How Is It Different?

Olmos Park sits between Alamo Heights and Olmos Basin Park to the south, and is bounded roughly by McCullough Avenue on the west and Devine on the east. The municipality intentionally has zero retail, zero apartment complexes, zero commercial buildings. It is a pure residential village of about 1,000 homes.

The housing stock leans older and grander than Alamo Heights. Many of the original 1920s estates remain. Lot sizes start at about 0.5 acres and run to multi-acre legacy estates with original architecture by Atlee B. Ayres and other prominent Texas architects of the period. Modern construction is rare and strictly regulated.

Olmos Park residents tend toward old San Antonio money, multi-generational property holders, and ultra-high-net-worth buyers entering the market for the first time. The buyer profile is less military than Alamo Heights for one reason: there is little inventory at typical even-senior-officer pay grades. An O-6 with full BAH and retirement pay is usually priced into a smaller subset of the inventory.

What Makes Terrell Hills the Smallest of the Three?

Terrell Hills sits north of Fort Sam Houston, bounded by Austin Highway on the south, Broadway on the west, and Eisenhauer to the north. It is the youngest of the three enclaves (incorporated 1957) and has a higher proportion of mid-century ranch and traditional homes than Alamo Heights or Olmos Park.

For military families, Terrell Hills is the natural choice. Fort Sam Houston is a 10-minute drive. JBSA-Randolph is 15 minutes via Loop 410. The Brooke Army Medical Center is also at Fort Sam, making it a frequent landing pad for senior military medical officers and their families. I have helped multiple retired O-5 and O-6 clients buy here precisely for that reason.

The lot sizes in Terrell Hills run a quarter to a half acre with strict setback and tree-canopy regulations. The school anchor is also Alamo Heights ISD, which is the unifying thread across all three 78209 cities. The schools alone justify the price floor for many military families on a final PCS to San Antonio.

Can a Veteran Use a VA Loan in the 78209 Triangle?

The math that surprises most veteran buyers entering 78209: a $1.2M Alamo Heights home with full VA entitlement requires roughly $92,000 down ($1,200,000 minus $832,750 equals $367,250; 25% of $367,250 equals $91,813). A $1.4M Olmos Park home requires roughly $142,000 down. Conventional buyers at the same price point would typically put 20% down or $240,000 to $280,000 on the same homes.

VA jumbo eligibility runs on the same DTI rules as a standard VA loan, with most lenders requiring a 680 to 700 minimum credit score for the jumbo tier. The funding fee is the standard 2.15% for first-use, 3.30% for subsequent-use, and zero for disabled veterans with 10% or higher VA disability rating. More on VA loan structures here.

Which 78209 Enclave Is Right for Which Veteran Buyer?

The choice is rarely a 50/50 call. Most of my buyer clients land in one of three patterns: senior officer at JBSA-Randolph commuting daily goes Terrell Hills; retired O-6 or O-7 with school-age kids and luxury budget goes Olmos Park; physician spouse or attorney-civilian-veteran-spouse pair goes Alamo Heights for the walkability.
