The short answer is yes. But it takes more than just completing inspections. The inspectors who reach and stay above $100,000 per year have figured out how to increase the value of every appointment and build a steady pipeline of clients who return and refer. Here is how that works in practice.
The Math Behind Six Figures
Let’s start with the numbers. If you charge $450 per standard inspection and want to earn $100,000 in gross revenue, you need to complete about 222 inspections per year. That is roughly four to five inspections per week, which is very achievable for a full-time inspector with a solid client base.
At 300 inspections per year, you are looking at $135,000 in gross revenue. At 400 inspections, it is $180,000. After business expenses, a well-run solo inspector at 300 to 400 inspections per year can net $100,000 to $140,000.
The foundation is volume. But specialization and add-on services are what push the top-performing inspectors significantly higher.
How Add-On Services Boost Income
Every inspection appointment is a chance to provide additional services that clients genuinely need. These add-ons increase the revenue per visit without adding another client or another drive across town.
Radon Testing
Radon is a serious health risk in many parts of Oregon and Washington. A radon test adds $125 to $175 to an inspection appointment. The test deploys a passive canister or electronic monitor during your inspection, you pick it up later, and the lab sends back results. The additional time investment per appointment is minimal. Many clients want radon testing, especially buyers purchasing older homes or homes with basements or slabs.
Sewer Scope
A sewer scope inspection uses a camera to evaluate the condition of the main sewer line from the house to the city connection. This is one of the most valuable add-ons available because sewer line repairs are expensive and the problem is completely invisible to a standard visual inspection. Sewer scopes typically add $150 to $250 per appointment. In the Portland area, where older cast iron and orangeburg sewer lines are common, buyers increasingly expect this service.
Thermal Imaging
Many inspectors charge $150 to $250 extra for thermal imaging. At Trusted Home Inspections, thermal imaging is included at no extra cost because it makes every inspection more thorough and builds trust with clients. For inspectors who do charge for it, thermal imaging is a straightforward upsell that most buyers are happy to add, especially on older homes or homes with suspected moisture issues.
Mold Testing
When an inspection reveals moisture concerns or visible mold, clients often want sampling done. Mold testing services vary in price but typically add $200 to $400 per appointment depending on the number of samples collected and lab fees involved. In the Pacific Northwest, with our damp climate and crawlspace issues, this comes up regularly.
Pre-Listing and New Construction Inspections
Sellers increasingly want pre-listing inspections before they put their home on the market. New construction buyers want inspections at the final walkthrough or at multiple stages of construction. Both are growing markets and both tend to involve clients who are less price-sensitive than traditional buyers in a competitive offer situation.
What a Six-Figure Day Looks Like
Here is a realistic picture of an experienced inspector’s day at the six-figure income level:
Morning inspection at 8:00 AM on a 1,800 square foot home from the 1970s. Base fee: $475. Radon test: $150. Sewer scope: $175. Total for this appointment: $800.
Afternoon inspection at 1:00 PM on a 2,400 square foot newer home. Base fee: $525. Radon test: $150. Total for this appointment: $675.
Two inspections. Total revenue for the day: $1,475. That is around $350,000 in annualized gross revenue if you work 240 days a year at that pace, or about $130,000 to $160,000 net after expenses if you maintain that volume.
Not every day hits those numbers. Some days are slower. But the math shows why inspectors who have strong add-on attachment rates reach six figures well before they hit peak inspection volume.
Specialization as an Income Multiplier
Beyond add-ons, some inspectors develop specializations that command premium fees. Commercial inspections, large estate inspections, insurance inspections, and inspections for investors who own multiple properties all represent higher-fee niches. An inspector who becomes the go-to person for a commercial real estate firm or a property management company can build a very different income profile than a purely residential inspector.
The Role of Credentials in Getting There
Higher credentials allow you to charge more and attract more serious clients. A Certified Master Inspector (CMI) has completed at least 1,000 paid inspections and 1,000 hours of continuing education. That designation signals a level of experience that justifies premium pricing. Less than 3% of inspectors nationwide hold it.
Russ Motyko of Trusted Home Inspections holds the CMI designation with over 2,000 completed inspections and 12 years of general contracting experience behind him. Learn more about what the CMI designation means and why it matters.
The Bottom Line
Six figures as a home inspector is a realistic goal, not a fantasy. It requires building volume, attaching add-on services to most appointments, and maintaining the kind of quality that generates consistent referrals. Most inspectors who reach this level do so by year three or four, and many sustain it for years afterward.
