Buying a home can be stressful. It’s a huge investment on everyone’s part, so it’s only smart to work with a real estate agent who can guide you in the proper direction. Many buyers think that a home inspection is a necessary part of the process–and I agree. You should know exactly what you’re paying for, with no surprises down the road.

To better prepare yourself during this time, have a look at these five common issues found in home inspections:

Roofing

Nothing puts a wrench in homeownership like finding out you have to redo your roof. Improperly working gutters, damages, and age are just a few things that your home inspector should address. Sometimes roofs require simple improvements to fix the issue, but a complete replacement will cost you.

Electrical Wiring

If you’re in the process of buying a home–especially an older one–a thorough look at the electrical wiring is paramount. Worn or outdated systems can be a huge safety hazard and need to be addressed immediately.

Heating and Cooling Systems

Older heating and cooling systems are not only costly to fix but are also less energy-efficient as newer models. A well-maintained unit can last for years, but it’s always important to check its condition before you invest.

Insulation and Ventilation

Improperly installed vent fans, especially in bathrooms, are a common issue found in inspections. Moisture problems, such as mold, can easily grow in a poorly ventilated room. Inquire about any “cold spots” in the house, which can indicate poor insulation.

Foundation Issues

A solid foundation, both literally and figuratively, is the basis of happy homeownership. Any structural damage you see can be evidence of bigger issues, and should be addressed first and foremost.
