Many people think that serious defects in a home are easy to spot, but the truth is, often the most serious and costly problems can only be detected upon very close inspection. When you are considering buying a home, look for the following six telltale signs of potential problems.

1. Roof

Leaks are the most common problem with roofs, and are challenging to detect from outside. However, from inside the  attic, you can often see water marks where there is a leak.

2. Plumbing System

Make sure you are confident that both water systems: the one that brings fresh water in, and the one that takes sewage out, are functioning properly before signing on the dotted line.

3. Electrical Systems

Before you agree to buy you want to make sure that the electrical system is safe and does not present a fire hazard.

4. Heating and Cooling Systems

Be sure to thoroughly inspect the heating and air conditioning systems in any home you are considering purchasing.

5. Bad Paint and Signs of Rotting

The paint inside and outside the house can reveal a lot about the condition of the underlying material. Check several places throughout the home, especially on basement walls and baseboards.

6. Cracks and other important signs

Cracks in walls, doors not closing properly and uneven floors can all be signs that there is a problem with the foundation. A bad foundation may not mean imminent disaster, but it could be used to bargain for a lower sale price, or you could have the owner repair the problem before the sale.
