During walk-through, you should always make sure the home is very presentable. This may not be directly covered by the inspector, but you could always put your personal touch for the aesthetics. Again, make the house presentable, but also free from defects and safety issues.
It is important that you make the house vacant long before the final walk-through. Prospective homebuyers would always assume that the house is not occupied so that the deal could always be closed anytime. Nine out of 10 times, homes that are successfully sold during final walk-through sessions are vacant. However, there could be problems to expect when a home has been vacant for a long duration. There might be presence of unwanted insects and termites. The cleanliness could also be questionable, though this aspect you could always make caretakers do the necessary action.
If in any case, the house is still occupied during a final walk-through, the seller should always make sure he is around to tour the prospective buyer in and out of the home. The homebuyer could always have pop-up questions when inspecting the house, and it is important that the owner or seller is there to answer every query so as not to build up suspicions and doubts in the mind of the buyer. Doing so is also like a conventional case of marketing. You could do a little persuasive sales talk to make sure the deal closes.
Where is the home inspector figuring in walk-through sessions? He might not be around. But his services could be very crucial in helping the seller identify defects and finally run important repairs. No defective home could ever be sold in a competitive price these days.
