Why Due Diligence Is the Most Important Step in Buying a Laundromat
Over 50 years and hundreds of laundromat transactions, Larry "Laundromat Larry" Larsen has seen the same pattern repeat itself: buyers who skip due diligence end up losing $50,000 to $300,000 on deals that looked great on paper. Even in May 2026, the laundromat industry remains uniquely vulnerable to seller misrepresentation because much of the revenue is cash-based, making financial verification critical.
"The seller's pro forma is a wish list, not a fact sheet," Larry says. "Your job is to verify every single number before you write that check."
Larry Larsen's 15-Point Laundromat Due Diligence Checklist
1. Verify Revenue Against Utility Bills
Request 24-36 months of water and gas utility bills. Cross-reference them against claimed revenue. A laundromat claiming $30,000 per month in revenue but showing $800 per month in water usage is a massive red flag. Water consumption directly correlates with wash cycles — the math either works or it does not.
2. Audit Coin Collection Records
If the store runs on coins, request detailed coin collection logs. Compare collection dates, amounts, and frequency. Look for suspicious patterns — consistent round numbers or sudden spikes before the listing date suggest manipulation.
3. Review Card System Transaction Data
For card-operated stores, request backend transaction reports from the payment processor. This data is nearly impossible to fabricate and provides the most accurate revenue picture available. Compare it against the seller's reported numbers.
4. Inspect the Lease — Every Clause
The lease is often more important than the business itself. Larry checks for:
- Remaining term — Minimum 10 years remaining (including options) for a viable investment
- Assignment clause — Can you transfer the lease when you sell?
- Exclusivity clause — Does the landlord guarantee no competing laundromat in the center?
- CAM charges — Common area maintenance fees that can escalate unpredictably
- Demolition clause — Can the landlord terminate early for redevelopment?
5. Assess Equipment Age and Condition
Every machine has a serial number that reveals its manufacture date. Larry inspects bearing wear, drum condition, drain valve operation, and control board reliability. A store full of 15-year-old top-loaders is a $200,000+ retool waiting to happen.
6. Evaluate the Plumbing Infrastructure
Old galvanized pipes, undersized drains, and failing water heaters are expensive problems that sellers rarely disclose. Larry checks pipe material, drain capacity, water heater age and BTU output, and backflow prevention compliance.
7. Check Zoning and Permits
Confirm the property is properly zoned for laundromat use. Verify all permits are current — business license, fire department, health department, and sign permits. Unpermitted improvements can trigger costly remediation.
8. Analyze the Competition Radius
Larry maps every competitor within a 2-mile radius, noting their equipment quality, pricing, hours, and customer volume. He uses the WashBizHub CLEANBI system to score location competitiveness across 17 weighted factors.
9. Study Demographics and Population Trends
A laundromat needs renters. Larry examines renter-to-owner ratios, median household income, population density, and growth projections within the trade area. A neighborhood transitioning from apartments to condos is a warning sign.
10. Verify Insurance and Liability History
Request the seller's insurance loss history. Frequent claims for slip-and-fall, water damage, or equipment injuries signal ongoing liability issues. Also verify adequate coverage limits for your acquisition.
11. Review Employee and Contractor Obligations
If the store has employees, review payroll records, workers' comp classification, and any pending labor claims. For attended stores, verify that staffing costs align with the seller's reported operating expenses.
12. Inspect Parking and Accessibility
Adequate parking is critical for laundromat success. Larry checks ADA compliance, parking ratio per square foot, shared parking agreements, and peak-hour availability. A store with 3 parking spots in a strip mall is a non-starter.
13. Evaluate the HVAC and Ventilation System
Dryer exhaust, makeup air, and climate control systems are expensive to replace. Larry inspects ductwork condition, exhaust fan capacity, and whether the HVAC system is properly sized for the heat load generated by commercial dryers.
14. Assess Technology and Payment Systems
Modern customers expect card payment, app-based loyalty, and real-time machine availability. Evaluate the current technology stack and factor in the cost of upgrading if the store is coin-only.
15. Calculate True Operating Expenses
Sellers often underreport expenses. Larry builds a ground-up expense model including water, sewer, gas, electricity, rent, insurance, maintenance, supplies, payroll, and capital reserves. The gap between the seller's claimed expenses and reality often exceeds $3,000 per month.
The 5 Biggest Red Flags Larry Has Seen
- Seller refuses to provide utility bills — Walk away immediately
- Lease has less than 5 years remaining — Your resale value drops dramatically
- All equipment is the same age — Means everything needs replacement at the same time
- Cash-only operation with no verification — Revenue could be inflated by 40-60%
- Seller is in a rush to close — They know something you do not

Frequently Asked Questions About Laundromat Due Diligence
How long does laundromat due diligence take?
Thorough due diligence typically takes 2-4 weeks. This includes time to gather utility bills, review the lease, inspect equipment, analyze demographics, and verify financials. Rushing this process is the most common mistake buyers make.
What is the most important item on the due diligence checklist?
Larry considers the lease the single most important item. A great business on a bad lease is a bad investment. Always verify remaining term, assignment rights, exclusivity, and CAM charges before anything else.
Should I hire a consultant for due diligence?
If you are spending $200,000 or more on a laundromat, a $397 consultation with an expert who has evaluated hundreds of deals is the highest-ROI investment you can make. Larry Larsen's Strategy Session covers every item on this checklist.
Can I do due diligence myself without experience?
You can follow this checklist yourself, but an experienced consultant will catch nuances that first-time buyers miss — like recognizing that a Speed Queen washer serial number indicates a 2008 manufacture date despite the seller claiming "newer equipment."
