If you have a particular property in mind, ask the buyer's agent who is representing you. If you don't have a particular property in mind, make a buyer's representation agreement with a REALTOR member of the MLS, and ask him/her when you find the property you want.
As has been mentioned, it is very difficult to do this without knowing many other parameters. Any agent can give you an estimate, however I recommend that you hire a buyers representative (agent) to help walk you through the process and to make sure your getting the best value for your dollar by negotiating on your behalf. Please feel free to contact me regarding your home search.
