“I not only bought, but also sold my investment duplex through Robert, who came highly recommended by a friend of mine. Robert and his team are consummate professionals and he has been a great resource for me over the years. When it came time to sell my property, he was the obvious choice. We listed in record time, received an excellent offer and closed within a week. I was evacuated during all of this, due to fires, but Robert did everything to insure that the transaction was easy for me and went through without a hitch. I’m in hospitality as a profession, and recognize outstanding customer service when I see it….and Robert is a simply amazing.”

“Robert and his team at Castle Hill were very responsive and professional in purchasing our duplexes. It’s really a blessing to work with their team while my husband is going through cancer diagnosis and treatment. We didn’t have to do much to finish the sale. We certainly will call him again if we decide to sell more of our duplexes.”

“My experience with Castle Hill Duplex was amazingly easy; strong words for a complex real estate transaction with lots of chances to be stressful and worrisome. They were straightforward, responsive, and a honest partner in achieving the outcome that was best for both of us.”

“Robert and his team at Castle Hill were a breeze to work with. They came in with not only a great offer for my client but great terms as well. I hope to see Castle Hill and their team on the other side of a transaction again in the future! If you have a chance to work with them you won’t regret it, thanks again Robert!”

“Approaching our retirement, Sue and I contacted Robert with a proposal to work together on another sale of our remaining duplexes. It was, as most real-estate transactions are, challenging, but solvable. Robert (and of course his capable team) deserves a lot of praise for providing level headed response/s, and action/s to every glitch that popped up. Much to our relief, I might add. Trustworthy, absolutely.”
