What Differentiates Castle Hill From Other Brokerages?

Brokerage and Investment Experience

Broker/Owner Robert Grunnah has sold more residential property than 99% of local real estate agents, including a record 2,000+ duplexes and fourplexes, some of which he has owned himself. This level of mastery is unparalleled among real estate professionals.

We help with renovations

Our in-house construction team will meet with owners to determine minor or major improvements that will help maximize re-sale value, and we'll perform the work on your behalf.

Our Investor Database

In addition to buying properties outright from owners ourselves, we have a comprehensive list of investors and agents that we work with that are often able to acquire listed properties immediately, reducing cost and headaches of long sales.
  • I am extremely pleased with my experience in selling my Austin fourplex. Robert and his team made everything so easy for me, and my fourplex had several offers, all above the listing price. Robert and his team were always there if I had a question or concern and the process was seamless. I would gladly work with Castle Hill again.
