How to Buy a Commercial Cleaning Business with an SBA Loan

Before approaching any commercial cleaning business for sale, establish clear acquisition criteria — minimum $200K SDE, recurring contract revenue representing 80%+ of total revenue, no single client above 25% of revenue, and a geographic market you can operate or manage. Contact 2–3 SBA-preferred lenders or work with an SBA-experienced business broker to get a pre-qualification letter based on your financial profile, credit score (minimum 680 recommended), net worth, and relevant experience. Pre-qualification signals seriousness to sellers and brokers and defines your realistic purchase price ceiling before you invest time in due diligence.

Work with a lower middle market business broker who specializes in facility services or has active commercial cleaning listings. Review confidential information memorandums (CIMs) for businesses matching your criteria. Prioritize targets with multi-year contracts, verifiable payroll records, diversified customer bases, and an owner willing to provide 30–90 days of transition support. Request 3 years of tax returns, P&L statements, customer contract summaries, and employee rosters before signing a letter of intent. Flag any business with significant 1099 worker usage, verbal-only client agreements, or a single client representing more than 25% of revenue — these are underwriting red flags that will slow or kill SBA approval.

Once you identify a target, submit a non-binding letter of intent (LOI) specifying the proposed purchase price, deal structure (SBA loan amount, seller note percentage, equity injection), due diligence period (typically 30–45 days), and transition terms. Most commercial cleaning acquisitions in the $750K–$2.5M range are structured with an SBA 7(a) loan covering 80–85% of the purchase price, a 10% seller note on standby, and 10–15% buyer cash. Open escrow and engage a transaction attorney experienced in small business acquisitions to draft or review the asset purchase agreement.

Due diligence on a commercial cleaning acquisition must go beyond financial statements. Review every service contract for term length, cancellation clauses, auto-renewal provisions, and pricing escalators. Calculate actual historical churn — not just what the seller claims. Audit payroll records to verify worker classification (W-2 vs. 1099), confirm workers' compensation and general liability insurance are current and review claims history, and physically inspect all cleaning equipment, vehicles, and supply inventory. Interview the operations supervisor or lead employees to assess whether the team will stay post-closing. Any material misrepresentation discovered here should be reflected in a price adjustment or deal re-structuring before proceeding to lender underwriting.

Provide your SBA lender with the completed loan application including: signed purchase agreement, 3 years of business tax returns, 3 years of personal tax returns, personal financial statement, buyer resume or experience summary, business plan with financial projections for years 1–3, customer contract summary with revenue breakdown, and the seller's seller's discretionary earnings (SDE) or EBITDA calculation with add-back schedule. Lenders underwriting commercial cleaning acquisitions will specifically stress-test revenue concentration and contract stability — be prepared to explain customer relationships and provide written evidence of contract renewals or customer retention history.

After receiving a conditional loan commitment, work through any lender conditions — which commonly include an independent business valuation (required for SBA loans above certain thresholds), a life insurance assignment on the buyer equal to the loan amount, hazardous materials confirmation for cleaning chemical storage, and finalization of the seller note subordination agreement. Coordinate with the seller on customer and employee communication plans. Finalize the asset purchase agreement, bill of sale, non-compete agreement, and transition services agreement with your attorney. Wire closing funds and sign loan documents at closing.

At closing, prioritize two immediate objectives: retaining key employees and reassuring top clients. Work alongside the seller during the agreed transition period — 30–90 days is standard in commercial cleaning acquisitions — to be personally introduced to major account contacts, shadow supervisory staff, and learn the scheduling and QC systems. Avoid making major operational changes in the first 90 days. Monitor contract renewal dates closely in the first year and proactively contact clients nearing renewal to confirm service satisfaction. Track monthly recurring revenue against your acquisition model and begin building your own client relationships to reduce any remaining dependency on the prior owner.
