What a client had to say about their experience... 

My wife and I will be moving into our new home in Hayward this week. We are excited and feel very fortunate to have been represented by Joanne Gardiner of Advantage Realty, Union City, CA. Since we were moving from Denver, CO our on-site presence was challenged and Joanne simply eliminated that as an issue. A large part of our search was being done via the Internet, particularly the MHVillage website. We were able to shop several homes in the area and every time we found a home so well described and documented with numerous pictures we would discover they were Joanne Gardiner listings. These listings literally, lead the viewer through the home "showing" the property at its best. By the time we actually visited the property, we already knew the layout and could better imagine ourselves living there.  She lead us through the entire process of qualifying, searching for a home, offering and buying a very nice property we know we will enjoy. We were so impressed with her thoroughness that the process was a fantastic experience. She anticipated every roadblock, maneuvered us through various financial, local municipality and necessary inspection issues. We never had to worry about not being extremely satisfied with her service and the resultant home purchase. Buying a home can be very personal and self-exposing, but Joanne made us feel like part of the Advantage Realty Family, they were all working for us, to help us find the property we had been hoping to make our home. Joanne Gardiner has won our confidence. She will be our Realtor for some time to come.  We would be foolish to let her get away. Many thanks for being a consummate professional at every level.
