A due diligence checklist for laundromat buyers

Due diligence is the stretch between an accepted offer and closing where you verify everything the seller claimed — the revenue, the lease, the equipment, and the operations. It is the most important work in the whole purchase, because it is your only real chance to confirm the income is genuine and the store will keep producing it. Use the checklist below, give it two to four weeks, and do not remove your contingencies until every item holds up.

What is laundromat due diligence

Once your offer or letter of intent is accepted, the seller opens the books and you confirm the story. The goal is simple: prove the seller's discretionary earnings are real and durable, and surface anything that should change your price or end the deal. This is also when the red flags tend to appear. Bring in help where it counts — an accountant to review the financials and an attorney for the purchase agreement and lease assignment are money well spent on a six-figure purchase.

Financial documents to request

Ask for, at minimum:

• Three years of tax returns and profit and loss statements
• Water and sewer bills, two to three years
• Bank deposit records showing cash and card deposits
• Card or app payment-system reports, if the store is not pure coin
• Utility bills for gas and electric
• The lease and any amendments
• An equipment list with ages and any service records
• Vendor and service contracts (collections, repairs, vending, ATM)

If a seller cannot or will not produce these, treat that as information in itself. A well-run store has this paperwork ready.

How to verify the revenue

This is the heart of due diligence. Reconcile the seller's stated revenue against three independent views: tax returns, bank deposits, and water usage. They will not match to the dollar, but they should land in the same range, and reported income on the tax return is a useful anchor because owners rarely overstate income to the IRS.

A worked water-usage cross-check

Water is the strongest check because washers use a predictable amount per cycle and the utility bills it independently. Suppose a front-load washer fleet averages roughly 30 gallons per cycle (confirm the real figure for the specific machines), and the water bills show about 150,000 gallons of metered use over a year. That implies roughly 5,000 wash cycles. At an average vend price near $4, the washers would generate about $20,000 a year — before dryers, wash-dry-fold, or vending. If the seller claims the self-service washers bring in $60,000, the water simply does not support it, and you need an explanation you can verify. The full method, including dryer and service revenue, is in how to verify a laundromat's revenue. Once the numbers hold, re-test the price with the valuation calculator.

Lease and assignment

A laundromat is tied to its location, so the lease can make or break the deal. Confirm:

• Remaining term and renewal options
• Base rent and any scheduled or CPI increases
• Pass-through costs (taxes, insurance, common-area charges)
• That the landlord will assign the lease to you or issue a new one on similar terms

Get the assignment in writing early — a landlord who will not assign or renew can end a deal at the last minute. Details in reviewing a laundromat lease.

Equipment inspection

Inventory every washer and dryer with its brand, model, approximate age, and condition. Ask what has been repaired or replaced and who services the machines, and run a load in as many as you can during your visit.

Budgeting for replacement

Machines near the end of their life mean a replacement bill is coming, and that cost belongs straight in your offer. Efficiency also drives the water and gas that are a store's largest variable costs (Energy Star is a useful reference on efficient commercial equipment). A fleet that is half worn out can justify thousands off the price — see how long commercial washers and dryers last.

Operations, staffing, and legal

Understand the day-to-day: hours, whether the store is attended, payroll and any employees who would transfer, vendor relationships, and open repairs or code issues. Confirm which licenses and permits the store holds and whether they transfer to you. If the store runs wash-dry-fold or delivery, check which commercial accounts are under contract and whether they come with the sale, since that recurring revenue may be a big part of the value.

What to do if the numbers do not match

A gap between claimed and verified revenue is not automatically a dealbreaker, but it shifts the burden of proof to the seller. Ask for the specific records that would explain it — a recent price increase, a seasonal pattern, an added service. If the explanation cannot be documented, do one of three things: discount the price to the revenue you can actually verify, restructure with more seller financing tied to performance, or walk away. Never close on income you cannot prove; there are other laundromats for sale.

The pre-close checklist

Before you remove contingencies, confirm you have:

• Reconciled revenue across tax returns, deposits, and water usage
• A lease assignment or new lease in writing
• A full equipment inventory with ages, condition, and a repair budget
• Verified utility costs, especially water and sewer
• Payroll and staffing understood
• Licenses, permits, and vendor contracts confirmed to transfer
• Payment-system reports for card or app stores
• Confirmation of whether seller financing is available
