This will help you determine a price that makes sense. The beautiful thing about being the buyer is that the service of a professional Realtor is of no cost to you and is one of the best ways of getting an idea of the value of the home and its history. If you don't have a Realtor I honestly think that should be your first step. I promise you, its not just because thats what I do for a living but its the best way of protecting yourself. Think of it as if you were going to court you would want someone who knows the law to represent you, so you hire a lawyer. We are specialists in Real Estate so we are educated in protecting people in the purchase or sale of their home.
