to avoid getting scammed, ask a friend who bought a house who their agent was, or generally ask around for established real estate agencies in your area.
An agent makes a lot of money when you buy a house, so they will be very happy to explain everything to you.
YOu can also talk to your bank (the number on the back of your bank card), they will help you get a pre-approved for a mortgage, and explain the terms. Again, this is their business and they will be happy to telp.
