The closing is typically held at the title company during normal business hours and will take about an hour. The walk through is generally scheduled either the evening before closing or on the day of closing. If the seller agreed to complete substantial repairs, it is probably a good idea to do the walk through at least a day or two earlier so that there will be time to rectify problems you find with the work that has been done. However, since it is so easy to do damage to the property while moving out, you typically want to do the walk through as close to closing as possible. The purpose of the walk through is to confirm that the the property is in the condition that the seller agreed to leave it in.
