If you’re like millions of people who will move into a new home this year, chances are the home you move into won’t be a new one. According to data from the National Association of Realtors, in 2016, approximately 700,000 of the 6.1 million homes sold were new. That means nearly 90 percent of homebuyers moved into a home that someone else had already lived in, and as a result, may be taking on problems that they didn’t know about.

A good way for homebuyers to be aware of potential problems with a home – and gauge the potential costs – is to have a home inspection. A home inspection by a certified professional provides a bit of assurance regarding the home’s quality and the effectiveness of its key systems like air conditioning, heating, roof and more.

According to the American Society of Home Inspectors, a home inspector checks a host of things, including the roof, foundation, electrical systems, interior walls, doors and major systems in the home, such as plumbing, heating and cooling. However, the extent of these inspections and the training for inspectors varies by state.
