You may also want to consider a home inspector to find out if your home needs any repairs beforehand. Most buyers are going to require this as part of the contract anyway. Most of the companies who do this are extremely thorough. If something has gone bad or is on its way out, chances are they are going to find it. Even if it is something you are not going to fix it, you can still disclose it to would be buyers.
If their home inspector finds an issue you could or should have been aware of, it may put doubt in a buyer’s mind. Nothing is worse than looking like you may have been trying to hide something. I wonder what else they are not telling us. If they didn’t do… what other maintenance should we be worried about? Some issues might also give a buyer an easy out of the contract if they are looking for one already.
