How to Buy a Laundromat: Valuation, Due Diligence and the Water Bill Test

Buying an existing laundromat can be one of the most practical ways to own a cash-flowing small business. It can also be one of the easiest ways to overpay, because many stores have a history of cash revenue that is hard to verify. This guide walks through how buyers value a store, how to test the seller's numbers, and how to protect yourself in the deal.

How laundromats are priced

Brokers usually price a laundromat as a multiple of its earnings:

• Net operating income (NOI): revenue minus operating costs, before debt, depreciation and owner pay
• Seller's discretionary earnings (SDE): NOI plus the owner's salary and personal perks run through the business

Multiples in the range of roughly 3 to 6 times annual net are commonly discussed, but the right multiple depends on:

As of 2026, verify multiples with brokers and recent local sales.

Step 1: Gather the documents

Ask for these before you make a firm offer, or make the offer contingent on them:

• ☐ Two to three years of business tax returns
• ☐ Twelve to twenty-four months of bank statements
• ☐ Twelve to twenty-four months of water, sewer, gas and electric bills
• ☐ Payment system and card reports
• ☐ Equipment list with brand, model, capacity, serial number and year
• ☐ Repair and parts invoices
• ☐ Lease and all amendments
• ☐ Wash-and-fold and commercial account records, with any contracts
• ☐ Payroll records if staffed

Step 2: Run the water bill test

Washers use a fairly predictable amount of water per cycle. That makes water bills one of the best independent checks on revenue.

Estimated washer cycles = (Annual gallons × share used by washers) ÷ average gallons per cycle

Estimated washer revenue = Estimated cycles × weighted average vend price

Worked example

A store's own water meter shows 1.6 million gallons over 12 months. The buyer estimates 90% goes to washers (the rest to restrooms, cleaning and a sink). Distributor data suggests the machine mix averages 26 gallons per cycle.

• Washer gallons: 1,600,000 × 0.90 = 1,440,000
• Cycles: 1,440,000 ÷ 26 = about 55,400
• At a weighted average vend of $4.80: about $265,900 in washer revenue
• Dryers add roughly 25% to 40% of washer revenue: about $66,500 to $106,400
• Estimated self-service revenue: about $332,000 to $372,000

If the seller claims $480,000, something does not add up. If the tax returns show $345,000 and bank deposits show $352,000, the evidence lines up, and the buyer values the store on that range.

Warning: Confirm the meter serves only the laundromat. Shared meters with neighboring tenants are common and can make the store look far busier than it is.

Step 3: Reconcile three sources

Revenue claims should be supported by at least three of these: tax returns, bank deposits, card or app reports, the water estimate, and your own observation of the store at busy and slow times. Be very cautious with sellers who say the true revenue is higher than what they reported to the IRS. You would be paying a multiple on income that cannot be verified.

Step 4: Inspect the equipment and building

Hire a distributor technician or independent laundry technician to inspect every machine, plus the water heaters, boilers, venting, drains and electrical panel. Ask:

• How many machines are out of order today, and for how long?
• How old is each machine, and are parts still available?
• What would replacing the oldest third cost?
• Are the water heaters sized correctly and in good condition?
• Are dryer vents clean and properly installed?

Commercial washers in busy stores are often expected to last around 10 to 15 years, with dryers sometimes longer. Older fleets should lower your price.

Step 5: Secure the lease

The lease can be worth more than the machines. Before closing:

• Confirm total remaining term, including options, at least matches your loan term
• Get the landlord's consent to assign the lease or sign a new one
• Look for an exclusive-use clause preventing another laundromat in the center
• Avoid demolition and relocation clauses
• Get a signed estoppel certificate confirming rent, term and no defaults

Step 6: Structure the deal to protect yourself

• Use an asset purchase, so you buy equipment, lease rights and goodwill, not the seller's liabilities
• Include a non-compete that prevents the seller from opening nearby
• Ask for a transition period where the seller trains you
• Consider a seller note or escrow holdback that can be reduced if revenue representations prove false
• Confirm any equipment loans or liens are paid off at closing

A sample offer

A store is listed at $420,000 based on $140,000 of claimed net. The buyer's analysis supports $310,000 in revenue and $95,000 in real NOI after adding missing repair and labor costs. Half the washers are 14 years old.

At 3.5 times $95,000, the store is worth about $332,500 before equipment issues. Allowing for some near-term replacement, the buyer offers $285,000, with a $40,000 seller note, contingent on a lease extension giving 15 years of total term.

Your first 90 days after closing

Buying the store is the start, not the finish. A good takeover plan protects the revenue you just paid for:

• Days 1 to 30: change locks, safe codes and payment system logins; transfer utilities; fix or remove every out-of-order machine; deep clean the store; introduce yourself to regulars and staff; update the Google Business Profile.
• Days 31 to 60: survey competitor prices and raise vend prices if justified; add card or app payment if the store is coin-only; relaunch wash-and-fold with a clear per-pound price; improve lighting and signage.
• Days 61 to 90: launch pickup and delivery in a small radius, start loyalty promotions, review revenue per machine, and plan equipment replacements.

Customers notice quickly when a store is cleaner, brighter and fully working, and that is often enough to lift turns per day in the first months.

Working with brokers and distributors

Most laundromats are sold through business brokers, and many equipment distributors also broker stores. They can be excellent sources of listings and local knowledge, but remember who pays them: brokers are usually paid a commission by the seller, and distributors profit when buyers replace equipment. Use them for information and introductions, and do your own verification. Ask every broker the same questions: why the owner is selling, how long the store has been listed, whether any offers fell through and why, and whether the landlord has been contacted about the lease.

Due diligence red flags

• Tax returns far below claimed revenue
• Water use that does not match claimed volume
• A lease with less than five years remaining and no options
• Many machines out of order, or no repair records
• A new, larger competitor opening nearby
• A seller unwilling to stay for a transition period

The bottom line

Buy laundromats on verified numbers, a long secure lease, and a realistic view of equipment life. Rebuilding the seller's numbers yourself is the most valuable work you will do before signing.
