I'm buying a house from the group that is selling the house on Mainberry. Contact any real estate agent and they can help. My agent is Kimberly Gomes at Century 21 on Schnoor in Madera. Even if you don't go with her, she can give you all the information.
Rather than call a listing agent on any home you are interested in, you need to find your own Realtor. One who will represent you and not the seller. A selling agent represents the seller, not you. Search here on Trulia and I am sure you will find some good agents. Good luck.
