Ron has made a great point. That is what we do as a Real Estate Agent. We work for you on the Buyers side in this case. Which like Ron said we are paid from the Seller's proceeds. If you'd send me the address I would be happy to see what I can find out for you. Besides you mentioned that you are going to live in the house for at least 2 years. Right now you have no where to go in value but up if you purchase at the right price. Once again that's our job or at least mine, to make sure that you are not paying to much for a property. Please let me know if I can assist you in any way.
