  • Diane helped me buy a home

      Diane was an excellent agent to have to buy a place. There was no pressure, and she has a talent to asked the correct questions to see if you like the listing or not. Also she was great on explaining what I needed to do every step of buying a place. She is a very nice person to used to buy. I would used her again if I was going to buy another place.

    • Diane listed and sold my home

        Excellent. She was very forward thinking and extremely knowledgeable about the property and through the entire contract process. She got us pre-qualified in a matter of hours on a Saturday in the LATE AFTERNOON. A REAL REALTOR!

          Diane is so knowledgeable about the Sun City real estate market and made the search and buying process wonderful. She was there for me every step of the way. I highly recommend Diane when buying a home in AZ.
