Shawn P.

"Robert and his team at Castle Hill Investments have been excellent to deal with for the past two years. With attention to detail, the entire team at Castle Hill has always worked their hardest, especially when compared to other folks in the Austin Real Estate market."

Serena C.

"Robert has extensive knowledge of the duplex/investment property market and has a very professional team that are strong advocates for their clients. Castle Hill does a great job of being very clear with buyers about what their clients are willing to do and lessens the work for their clients. Adrienne was very professional and thorough. They worked hard to sell our duplex and it sold for full price. Definitely recommend them if you have investment property to sell!"
