Common Questions

What homeowners ask first.

All Questions
What is Castroville known for, and who typically builds there?
Castroville is the Medina County seat and one of the oldest towns in Texas, founded by Alsatian settlers in 1844. It still keeps active Alsatian traditions and some of the most distinctive 19th-century vernacular architecture in the state. Our clients building near Castroville are usually drawn by lower land prices, the Medina River, and easy San Antonio access — without paying for a Bexar County address.
How far is Castroville from San Antonio?
Castroville is about 25 miles west of San Antonio on US-90 — roughly 25 to 30 minutes in normal traffic. It's one of the closest rural-character communities to the city in our service area, and that's making it a more and more popular pick for buyers who want land and space at a price point Bexar or Kendall counties simply can't match.
What school district serves Castroville?
Castroville is served by Medina Valley ISD, covering most of western Medina County — Castroville, Natalia, and the communities around them. Enrollment has grown steadily as more families move out from the San Antonio metro. It's a solid district with smaller class sizes than most SA-area suburban schools.
What are land prices and lot sizes like in Castroville?
Medina County land near Castroville is among the more affordable in our service area. Rural tracts of 3 to 10 acres are common and priced well under comparable acreage in Kendall or Comal counties. In-town and ETJ lots come in smaller sizes. Parcels along the Medina River corridor carry a premium, but even those are strong value next to Hill Country proper.
What utilities are available in the Castroville area?
Castroville has municipal water and wastewater service inside city limits, run by the city. Properties outside city limits in Medina County typically need private wells and septic systems. The Medina River brings floodplain considerations for some parcels along the corridor — we review FEMA mapping and county flood data as standard site evaluation.
