Ron and Debbie are correct about outstanding code violations as well. You need to check with the county and municipality to make sure there are no outstanding code violations such as exterior repairs, maybe broken windows, painting - the list goes on. (However, I have been successful in negotiating with the seller(s) to fix some of the code violdations as part of the accepted offer). In addition, in our state, I am finding more and more that once the new owner has closed, the city is usually agreeable to extend any dates and deadlines realizing of course that they need time to get settled. So buyer beware is a good rule of thumb here, and check with your individual municipality to see how that is handled. Title company may be of assistance as well.
