Never, Never purchase real estate from the listing agent, ie the one with the sign in the yard! He/She works for the SELLER! Secure your own REALTOR; he/she usually works for the commission paid by the seller so he/she works for YOU- for FREE! He/she is loyal to you and you alone. Why risk a major investment without representation? You would not go into a court of law without representation, so why not have a REALTOR on your side during your closing?
