Buying a home is typically the biggest investment you will ever make, so it's important to get a home inspection because the inspector should be able to discover and document defects that may or may not be obvious to you as a prospective buyer. Such defects can range from simple replacements or repairs, to severe damage or safety and health concerns. Additionally, most mortgage companies require a home inspection on a property before approving the home loan. Read InterNACHI’s Top 10 Reasons to Get a Home Inspection.

It is important to choose a home inspector who is qualified and holds a license or certification in the field. Many jurisdictions do not regulate home inspections, meaning that anyone could call themselves a home inspector. However, just because someone performs home inspections doesn't mean that they're actually qualified to do so. If you are buying or selling a home in an unregulated jurisdiction, make sure to look for a home inspector with the proper certifications. If you are located in a state or province that does require licensing of home inspectors, you should hire only a licensed professional.

Contact your state by phone or online to find out whether they license home inspectors, and what qualifications they're required to have. License numbers in licensing states may vary in appearance, but you should be able to independently verify it. If your state doesn't require licensing, find out what qualifications and certifications your home inspector has. The International Association of Certified Home Inspectors – InterNACHI® – is the largest and most trusted home inspector association in the world. Its members undergo rigorous training to become Certified Professional Inspectors (CPIs)®. They also follow a Standards of Practice and adhere to a Code of Ethics. Also, the Master Inspector Certification Board grants qualified inspectors the title of Certified Master Inspector® (CMI®), which is the highest professional designation in the inspection industry. Find out if your inspector is licensed and/or a CPI or CMI® before you hire him or her. This will ensure that you are hiring only an individual who has received the best training to become a home inspector.

There is no set cost for a home inspection. The cost will vary based on the local market, the geographic region, the scope of the inspection to be performed, and more.

Before the inspection, you should find out what will be included in the inspection and what won't, and these details should also be outlined in the inspection agreement that you will need to sign prior to the inspection.

Depending on the home's age, size, and location, as well as the home inspector's own work protocols and ethic, your home inspection may take three hours or longer. Adding square footage, outbuildings, and/or ancillary services (such as mold or radon testing) will increase that time. It may be necessary for your inspector to bring in a helper for a very large property. If your general home inspection takes significantly less than two to three hours, it may indicate that the inspector was not thorough enough.

A home inspection is usually scheduled after an offer has been made and accepted, but before the closing date. That way, the inspector can rule out any major defects that could be dangerous or costly. In rare cases—due to timing or contractual issues—the inspection can be scheduled after the closing date. If this is the case, the home buyer should schedule the inspection for the earliest possible date after closing.

What if your home inspector is also a licensed contractor? Sounds great, right? Not always. Although it may seem convenient to have an inspector who is also a contractor, it poses a conflict of interest. According to InterNACHI's Code of Ethics:


If an inspector financially benefits from finding any defects, this can impact the accuracy of the report (whether intentional or not). Make sure the inspector you hire abides by a Code of Ethics and Standards of Practice.

If your home inspection reveals any problems, it is important to understand the severity of the defect. For example, a missing shingle or dirty air filter can be easily fixed at a low cost. However, if the defect is more extreme, such as a major foundation crack, wood-destroying organism infestation, or evidence of mold, you should find out how these problems can be addressed, and whether you can negotiate their cost with the seller.
