There are a number of things that real estates do other than selling and marketing of the property. Some of the other things that they do include things like: * Dealing with a lot of paperwork for their clients * Negotiating the best deals for their clients. * Negotiate for homes for sale with the sellers and buyers on your behalf to get a good deal. * Liaise with a solicitor
However, it is important for you to understand that real estate agents do not deal with surveys. If you want a survey to be done, then it is highly advisable that you hire a surveyor to do the work for you.
