Unless you're buying brand new, expect your home to need some upgrades. Just be sure the issues aren't structural (such as those under "red light" below, which your home inspector can help you identify). Fixing these could run as much as $30,000, says New Jersey builder Jay Cipriani.
Better to go with a home needing cosmetic work ("green light") or at least a less extensive overhaul ("yellow light"). The investment you make in resolving these will improve your quality of life while living there and increase the resale value.
