Structure and Foundation

These are the big repairs, and big repairs are expensive. Definitely double-check with your inspector, but some good indications are seeping water in the basement, slanting floors, and cracks.

The Roof

Another costly repair is the roofing. Check for rot or damage, and be sure to consider that replacing roofing is expensive—and can require additional structural reinforcement if the new materials used will be heavier than the old materials.

Heating & Cooling Systems

How old is the furnace and what is its condition? How about the oil tank and water heater? And is there air conditioning? A home in Raleigh likely won’t sell for much without A/C.

Plumbing

Older plumbing is expensive to replace, and can be difficult to connect to newer plumbing systems. Check for leaks and the pressure, and consider the materials used in the current system, as bathroom or kitchen renovations could likely need plumbing additions or changes.

Electric Wiring

Old wiring can be a fire hazard, especially if it’s wired incorrectly. You may need to rewire or replace old systems.

Doors and Windows

Check for rot or damaged frames. Know that replacing old windows and doors can be expensive, especially if they are of an unusual shape or size.
