I agree with Terry - take care of necessary repairs and obvious issues, and this sounds like one that is very visually obvious. If you do not, it may well diminish interest among buyers, delaying a sale, and you will likely face dealing with it when the inspection takes place. Your goal is to get there --- and anything that stands in the way of a likely sale should be taken care of prior to listing. Remember the old saying, "you have one chance to make a first impression....."
Good luck to you,
