Caldwell County offers historic homes near the Lockhart square, newer subdivisions on the edges of town, small-town houses in Luling, and acreage. Growth along the SH-130 and SH-21 corridors has brought new construction, while the rural areas keep a ranch-country feel. Prices vary by city and property type, so ask your agent for recent sales that match the home you want.
What buyers commonly look for:
Value - lower entry prices than many Austin-area suburbs
Land - lots and acreage in the rural parts of the county
Small-town life - courthouse squares, local events, and barbecue
Access to Austin and San Marcos - routes by SH-130, US-183, and SH-21
