Moving to Austin & the Hill Country
Moving into the Austin/Hill Country region means navigating a genuine correction in the Austin market itself, real Hill Country geography (I-35 corridor towns vs. more remote lake/wine-country towns reached by two-lane highways), and -- more than any other region in this Texas dataset -- a serious, recurring flash-flood hazard that shapes where and how people should buy.

Austin-Bergstrom International Airport (AUS) serves the whole region and sits closest to Austin proper, Buda, and Kyle. Interstate 35 is the region's central spine, running through San Marcos and Kyle south of Austin and up through Round Rock, Georgetown, and toward Waco north of it -- most of this region's Williamson County satellites (Round Rock, Cedar Park, Georgetown, Pflugerville, Leander) sit directly on or near I-35, while the Hill Country lake-and-wine towns (Lakeway, Bee Cave, Marble Falls, Horseshoe Bay, Fredericksburg, Kerrville) are reached primarily by two-lane state highways (RM 620, US-281, US-290) rather than interstate, meaning real, longer drive times to Austin's core job market.
Flash Flood Alley Is This Region's Defining, Recurring Hazard
This region carries the most serious, best-documented flash-flood risk of any region in this Texas dataset. The Texas Hill Country is known to the National Weather Service and the Guadalupe-Blanco River Authority as 'Flash Flood Alley,' among the most flash-flood-prone regions in North America, and the historical record here is not abstract: the catastrophic July 4-5, 2025 Guadalupe River flood killed 135 people statewide (116 in Kerr County alone, including at least 27 at Camp Mystic) -- Texas's deadliest flooding disaster on record. Wimberley's May 2015 Blanco River flood killed 13 people and destroyed roughly 400 homes. Lake Travis itself has a documented history of dramatic surges (its 1997 record crest of 710 feet, and a July 2026 event that reopened its floodgates for the first time since 2019). A second, smaller July 2026 flood event affected both Kerrville and Fredericksburg. Anyone buying anywhere in this region's Hill Country half -- Lakeway, Bee Cave, Wimberley, Marble Falls, Horseshoe Bay, Fredericksburg, Kerrville, Dripping Springs, Buda -- should confirm a specific property's flood-zone status and elevation directly rather than treating this as a remote or historical risk.
Insurance Uptake Was Historically Low Before the 2025 Disaster
A sobering, directly relevant fact for anyone moving into this region: investigative reporting after the July 2025 flood found only about 2.5% of Kerr County homeowners carried flood insurance at the time, since standard homeowners policies exclude flood coverage everywhere. In direct response, Kerr County built a new flood-warning siren system with the Upper Guadalupe River Authority, and when a second, smaller flood struck the region again in July 2026, county officials credited the new sirens with a materially better outcome (one death rather than dozens, no missing-persons reports). Anyone buying near the Guadalupe, Blanco, Pedernales, or Colorado River systems in this region should treat separate flood insurance as essential, not optional, regardless of official FEMA flood-zone status.
Property Tax Complexity Across County Lines
Several member places in this region straddle county lines with genuinely different tax and school-district implications -- Pflugerville sits primarily in Travis County (not Williamson, despite the common association with its Williamson County neighbors), Prosper-style multi-county splits don't apply here but Dripping Springs, Buda, Kyle, San Marcos, and Wimberley all sit in Hays County with a consistently cited 1.73% effective rate, while the Williamson County towns (Round Rock, Cedar Park, Georgetown, Leander) share a roughly 1.61% blended rate. Confirm the specific taxing entities for any address directly rather than assuming a single regional rate applies.
Key takeaways
- AUS airport and I-35 serve the Williamson County/San Marcos corridor directly; the Hill Country lake-and-wine towns (Lakeway, Bee Cave, Fredericksburg, Kerrville) are reached by two-lane highways with real, longer drive times.
- This region carries the most serious, recurring flash-flood hazard of any region in this dataset -- the July 2025 Guadalupe River flood (135 deaths statewide) is the deadliest flooding disaster in Texas history, and Wimberley's 2015 flood and Lake Travis's own surge history are real, dated precedents.
- Only about 2.5% of Kerr County homeowners carried flood insurance before the 2025 disaster -- treat separate flood insurance as essential for any Hill Country property near a river system, regardless of FEMA flood-zone designation.
- Hays County (Kyle, San Marcos, Buda, Dripping Springs, Wimberley) and Williamson County (Round Rock, Cedar Park, Georgetown, Leander) carry different, consistently-cited effective property tax rates -- confirm the specific rate for an address rather than assuming one regional figure.
