About Us
Austin’s Trusted Cash Duplex Buyer
Robert Grunnah has been Austin’s leading cash duplex buyer since 2004, with over 1,200 duplexes and houses purchased in the Austin, TX area. As the founder of Castle Hill Duplex, Robert specializes in buying duplexes directly from owners — whether the property is fully occupied, partially vacant, in need of major repairs, or caught up in a complicated ownership situation.
Robert and his team understand what duplex sellers deal with that single-family sellers don’t: difficult tenant relationships, mismatched lease terms, deferred maintenance across two units, and the emotional complexity of selling an income-producing asset. That expertise means you work with a buyer who gets it — and makes offers that reflect the real-world value of your duplex, not a one-size-fits-all formula.
Castle Hill Duplex purchases duplexes and small multi-family properties in Austin. We buy duplexes in Round Rock, TX too.
