"My wife and I wanted to write you a quick email to let you know what an outstanding job you did. Being first time home buyers we were naturally pretty nervous. Your relaxed demeanor and willingness to answer all of our questions really put us at ease. You were also very quick to respond to any questions or concerns we had, not matter the time of day. We really feel like you had our best interest at heart. We dealt briefly with a couple of other realtors and they didn't even compare to you."
"You were an excellent property manager and we where so happy to have had you manage our place while we were overseas. We passed on your info to a few friends who will be looking for a property manager in the future."
