Home inspection valuations rest on EBITDA multiples reflecting inspection volume, inspector team depth, and service diversification. Calculate true EBITDA: take total revenue (standard inspections, radon, mold, sewer, energy audits, other services), subtract direct costs (inspection supplies, E&O insurance, vehicle costs, subcontractor fees if outsourcing services), subtract inspector payroll (employee compensation, benefits), subtract overhead (office rent, utilities, marketing), subtract technology and software costs, then subtract administrative costs. Your EBITDA is the baseline for multiple application.

The 3.5x-6x EBITDA range reflects buyer acquisition activity in the space. A home inspection company generating $200K EBITDA with 450+ annual inspections, 2 certified inspectors, strong realtor relationships, and 30% service diversification revenue trades closer to 5x ($1M) than 3.5x ($700K). The same company with solo inspector and no service diversification trades closer to 3.5x-4.2x ($700-840K). Inspector depth creates 1-2x multiple variance.

Inspection volume is the primary revenue driver. A home inspector typically charges $300-500 per standard residential inspection depending on property size, market, and urgency (rush inspections command 25-50% premium). Additional services (radon $150-250, mold $200-400, sewer $300-500) add $150-300 per transaction. A home inspection company performing 450 annual inspections at $350 average per inspection generates $157.5K revenue from core inspections. Add 30% revenue from services: $157.5K × 1.3 = $204.75K total revenue. At 55-65% EBITDA margins typical for the industry, this generates $112.6K-$133K EBITDA. This calculation shows how volume directly drives valuation.

Inspector coverage creates valuation uplift. A solo inspector company valued at 4x EBITDA operates at high key-person risk; if the inspector leaves, revenue collapses. Adding a second certified inspector (either employee or strong contractor relationship) valued at 4.5x-5x EBITDA because operational continuity is established. Three or more inspectors with cross-training valued at 5.5x-6x EBITDA. Each additional inspector effectively adds $100-150K annual revenue capacity. Document inspector tenure explicitly; inspectors with 3+ year tenure are retention anchors that justify retention bonuses post-acquisition.

Realtor relationships are both valuable and risky. Realtor-sourced inspections represent 60-70% of transaction volume for most home inspection companies. This concentration creates buyer concern: what happens if realtor relationships shift? Mitigate by: (1) documenting relationships explicitly (which realtors refer, annual volume), (2) developing direct-to-consumer marketing to diversify referral sources, and (3) seeking exclusive or preferred inspector agreements with major brokerages. A home inspection company with referrals distributed across 10+ realtors is less vulnerable than one relying on 2-3 offices. Buyers model scenario where you lose largest realtor referrer; show that remaining referrers generate 70%+ of base volume.

Service diversification increases revenue per transaction and margins. A home inspector offering only standard inspections achieves 50-55% EBITDA margins; one offering radon, mold, sewer, and energy audits achieves 60-65% because ancillary services carry higher margins. Calculate service revenue breakdown: (1) standard inspections 70-75%, (2) radon 10-12%, (3) mold/water 8-10%, (4) sewer/foundation 5-8%, (5) other 2-5%. This balanced service portfolio creates cross-selling opportunities—customers buying sewer scoping often also buy radon. Service attachment rate (percentage of inspections that include ancillary services) should be 40-50%.

Technology investment in reporting and CRM improves customer satisfaction and creates competitive advantage. Inspectors using modern digital reporting platforms (HomeGauge, HouseLens) achieve 10-15% premium pricing over traditional printed reports. Digital delivery within 24 hours improves customer satisfaction and realtor feedback, generating more referrals. CRM functionality enables follow-up marketing and repeat-customer targeting. Investment is $400-800 monthly but improves margins 3-5 percentage points through premium positioning and operational efficiency.

Regulatory compliance is table stakes. All inspectors must maintain current state licensing (if required), ASHI or NAHI certification, and continuing education requirements. E&O insurance is mandatory ($1.5K-3.5K annually); claim history matters. Buyers specifically verify licensing status and insurance coverage. Deficiencies trigger 20-40% discount requests.

Buyers actively acquiring home inspection companies include large home warranty companies (First American Home Warranty, 2-10 Home Buyers Warranty), pest/termite companies (Terminix, Orkin expanding services), real estate tech platforms (Redfin, Zillow), and PE-backed platforms. Their acquisition targets are companies with $100K+ EBITDA, 2+ inspectors, and strong realtor relationships. Strategic buyers bid 4x-5.5x EBITDA and apply operational synergies. Financial buyers bid 5x-6x EBITDA because they apply multi-location rollup strategies.

Timing matters. Home sales peak in spring/summer; close valuations in fall/winter using prior full-year data so seasonal variance is normalized. A company showing strong spring numbers might appear overstated.

Regulatory compliance includes state licensing, E&O insurance, and proper contractor licensing for any related services. Document all licenses and insurance. Compliance gaps trigger discount requests.
