The final walk through is conducted very close to the closing date, if not, the same day. It allows the buyer to walk through the home one last time and make sure the home is in the condition it was in when they viewed the home. You never know, maybe the house burned down since the seller moved out (I actually had a client who had that happen to them once). Anything could happen really, a leak, vandalism, or maybe your seller just left you with a big mess and a bunch of trash to throw away. The final walk through is your chance to make sure the house is in the condition you expect before you sign on the dotted line.
