Technically, no you are not obligated to do those minor repairs. However, these are usually the little problems that make selling and buying a headache. The best approach I think is to just go ahead and fix them. It is called being proactive vs reactive. You always save time and money being proactive vs reactive. This may be a problem later. You would hate for the buyers to walk through the home the day of closing when everythings out and all of a sudden they see a lot of these things and they think are we making a good choice? Can we back out now? Then your closing gets delayed because the buyers think the house doesnt look the same with all your nice stuff gone. Now they want money for little repairs. Sure we agents try to have everything under contracts. Sometimes it is hard to get emotions under contracts. Most buyers are scared anyway so if they feel like they dont want to move forward they will risk losing there earnest money before they get stuck with the house.
