I try to do the final walk-through with my buyer clients as close to closing as I possibly can. At that time, I give a check list to the buyer so they know what they are supposed to be looking at and for in the home. A lot of post-closing problems can be avoided if things are checked out properly beforehand. Allow adedquate time to see if the appliances are working, verify there are no water leaks, are if all inclusion are still there etc. My worst case walk-though story was a winter walk-through where the water had been turned off after inspections and when we turned it back on for the walk-through, water started pouring out of pipes in the garage. The wife started crying and the husband was stunned. We post-poned closing a few days until the repair work was done and everyone was finally happy!
