I am guessing you are buying the home since you have said in order to qualify for a conventional loan. If you were my buyer, I would have the seller fix the items. If the seller will not, I certainly would not put any money into the home until I was yours. You don't know for sure if the house will close for sure. There are way too many variables and risks to do this before the house closes if you are the buyer.
