A home inspection is a critical tool for you to help protect what may be the single largest investment you will ever make. There’s nothing worse than buying a home, and then later finding a number of issues that may be have been easily detected by a trained and highly qualified inspector. If you’re in the final stages of purchasing a home, here’s what you should know about a home inspection.

Why is a home inspection important?

You can expect several small expenses when you’re buying a home. These include application fees, homeowner’s insurance, legal fees, and more. Because you’re already spending so much money upfront, many buyers are tempted to skip a home inspection. Averaging between $350 and $600, a home inspection is a relatively insignificant expense that may help you in the long-run and at the very least give you peace of mind if there are no material issues uncovered during the inspection.

Here are a few reasons why a residential home inspection is worth the investment and the time:

1. It may help you avoid significant expenses later.

Ideally, a home inspection should reveal any major issues with the home. These aren’t things you would normally notice with a routine walk-through, such as a failing HVAC system, improper wiring, structural issues, and more.

2. It may help you create a maintenance plan.

Even if there are no significant issues with the home, you can expect to pay maintenance expenses as long as you live there. Over time, these expenses can add up. A home inspection could help you outline a maintenance schedule, so you can prepare for these costs in advance.

3. It may help identify any safety issues.

A home inspection can uncover safety issues, which may be very costly problems in addition to potential problems associated with the roof. Mold, carbon monoxide leaks, and lead are all significant safety issues that can threaten the health of your household members.

4. It may protect you from a bad deal.

When you sign a contract to purchase a home, you can add a contingency. This is a note that lets the seller know that you only agree to purchase the home if the home inspection meets your expectations.

If the home inspection reveals significant issues, you can choose to void the contract, ask the seller to make necessary repairs, or request a discounted price.

Without a home inspection, you’re buying the home as-is. If any problems arise after the purchase, they’re entirely your responsibility.

Do home inspectors offer a guarantee?

Though home inspections offer a substantial amount of protection for the home buyer, they generally do not come with a guarantee. There are simply too many factors that can go wrong with a home for a home inspector to take on this amount of liability.

However, some home inspectors may offer a limited guarantee, which is a refund of the money you pay for the actual inspection if you are not completely satisfied with the inspection. Some home inspectors may offer a home warranty with their home inspection services.

How to Find a Home Inspector

While you can certainly use this list to oversee a qualified inspector or perform an inspection yourself, it’s best to hire an expert to conduct the actual home inspection.

Many of these systems, including electrical and plumbing systems, require professional knowledge and expertise that most home buyers simply don’t possess.

A good home inspection may cost you a few hundred dollars, but it’s well worth the investment. Conducting a proper home inspection now may save you thousands of dollars (or more) down the road.
