78664 is one of Round Rock’s zip codes, an established part of this Austin-area suburb known for major employers and a mix of housing built over several decades. I’m Robbie English, Broker, REALTOR with Uncommon Realty, and here’s what actually matters here.
What This Part of Round Rock Offers
This area mixes established neighborhoods from the 1990s and 2000s with newer infill construction, giving buyers a range of price points and lot sizes rarely found in Round Rock’s newer, further-out sections. Round Rock is home to major employers including Dell’s headquarters, which has shaped demand and commute patterns across the city for decades.
What to Actually Check
Confirm the specific Round Rock ISD campus assignment, since attendance zones can vary street by street even within the same neighborhood. Ask about the age of major systems (roof, HVAC, water heater) on any home over 15 years old, and check whether an HOA applies, since older Round Rock neighborhoods vary in whether they have one.
