If you find a home that you like but the seller doesn't offer to include a warranty, you can request it as part of your offer to buy. The last thing a homebuyer wants after the shutdown is a malfunction in their new home, but it can happen. It's a good idea to get a home protection plan or warranty so you don't have to worry about it now or as you go. It will cover the associated costs if something goes wrong.
It's common for a seller to buy a home warranty and add it as part of their closing checklist for a new homeowner. This becomes an additional incentive for prospective buyers, but it also ensures that the former owner does not receive any complaints or communications from the new owner if something goes wrong after the closing date.
