Inside the house, look for things like stained ceilings, missing tile, broken windows and doors, heavily scratched floors and other signs of neglect. Outside, look for broken or missing shingles, patio pavers and tuckpointing. If you have a deck, check for cracks in floor boards and loose railings. Make a list of everything you see and then decide which things you're going to tackle. A real estate agent can be very helpful in determining what needs to be done and what doesn't.
