Neighborhood guide and local insights
Brentwood is one of Austin's original mid-century neighborhoods - built mostly between 1948 and 1955 when the city was expanding north of campus. The bones are good: 1,200-1,800 sqft brick and stone ranch homes on 7,500-10,000 sqft lots, mature pecan and oak trees, and a street grid that connects to everywhere without a single cul-de-sac. The 78757 zip puts you 10 minutes from downtown via Lamar, 8 minutes from the Domain, and walking distance to Burnet Road - which has become one of Austin's best food corridors. Foreign & Domestic, Lala's Little Nugget, Top Notch Hamburgers, Tacodeli, and Soup Peddler are all within a mile. The Crown & Anchor on Burnet still serves the same burgers it did in 1980. Original ranch homes start around $700K. Renovated and expanded properties run $1.1M-$1.6M. Tear-down and rebuild has accelerated over the past five years - new construction in the $1.8M-$2.5M range now mixes with the originals. The Brentwood Park area near Justin Lane holds value especially well. Schools are Austin ISD: Brentwood Elementary, Lamar Middle, and McCallum High School - which feeds the Fine Arts Academy. Brentwood Park itself has tennis courts, a swimming pool, and the historic Brentwood Park Pool that families have used since the 1950s. What makes Brentwood different from the bigger-name North Austin neighborhoods: it's still mostly its original housing stock. You can buy a real 1950s house with the post-war floor plan intact, then decide what to do with it. The neighborhood association is active, the streets are quiet, and the trees are tall enough to actually shade the sidewalks. Best for buyers who want a true urban neighborhood with mid-century character, walkable food and coffee, and the McCallum Fine Arts Academy zoning.
