Walk-Through Walk-through is the general term for the final walk through a home that a buyer does before finalizing the deal to purchase the home. The purpose of the final walk-through is to allow the buyer one last look at the home before they close the deal to buy it. This is the buyer's chance to make sure the home is in suitable condition, with any repairs performed that were agreed upon. It is also a chance to make sure nothing new has gone wrong with the home since the last time the buyer has visited. Some things that a buyer may check when performing their final walk-through include checking to make sure lights work and that plumbing is not clogged, testing all appliances for functionality, making sure doors and windows open and close properly, testing the heat and air conditioning of the home and ensuring all debris are removed.
