If you are interested in buying a home in Miami, you should contact a reputable Realtor who can help you do so. Our area uses a regional multiple listing service that contains ALL properties listed for sale. Once we understand your price range and needs, we can find homes that are available for you.
I work that area, so feel free to contact me and we will get together and put together an offer. As John said, there is no fee for my services to you, which include all the negotiations, assisting you with financing, inspections, and everything all the way to the closing table.
