Neighborhood guide and local insights
Clarksville is Austin's most walkable luxury neighborhood — a historic freedman's town founded in 1871, now in 78703, five minutes on foot from downtown. Median home price $2.2M. Austin ISD schools (Casis Elementary, O. Henry Middle, Austin High). One of the only Austin neighborhoods where you can walk to fine dining, trails, and downtown without getting in a car. The housing stock reflects 150 years of history. Original shotgun cottages and bungalows from the early 1900s sit alongside contemporary new builds and sensitive renovations on lots ranging from 0.1 to 0.25 acres. The neighborhood's historic designation (National Register) means you'll see period architecture preserved next to modern infill. Teardown lots trade at $800K-$1.5M for land alone. West Lynn Street is the commercial spine — Medici coffee, Cipollina wood-fired pizza, Jeffrey's fine dining, Josephine House, and Bar Peached are all within a few blocks. Pease Park and Shoal Creek Trail border the east side. The Whole Foods flagship at 6th and Lamar is a 10-minute walk. What makes Clarksville distinct: the combination of walkable daily life, historic character, and proximity to downtown that no other Austin neighborhood matches. The tradeoff is small lots, limited parking, and premium pricing for the location. Buyers here are paying for a lifestyle that doesn't require a car.
