The Water Bill Doesn’t Lie: How I’d Check a Laundromat Before Buying It

If I were buying a laundromat tomorrow, the first document I’d ask for wouldn’t be the profit and loss statement. It would be the water bill. Two years of them, straight from the utility.

Here’s why. A seller can round up a revenue number. A broker can build a beautiful spreadsheet. But the city meters the water, and every wash cycle uses a fairly predictable amount of it. The water bill is the one witness in the room with no stake in the sale.

I’m not a financial advisor, and this isn’t financial advice. What follows is how I’d think about verifying a deal, with hypothetical numbers so you can see the method.

Buying cash flow means buying a story

When you buy an existing business, you’re not really buying washers and a lease. You’re buying a claim about the future: “this store will keep producing roughly this much money.” The price is that claim multiplied. Small laundromats typically sell for somewhere around 2.5x to 5x seller’s discretionary earnings, and BizBuySell’s data on hundreds of recent sales puts the median around 3.5x.

So if the earnings number is inflated by $20,000, and you pay 3.5x, you just overpaid by $70,000 for money that doesn’t exist. That’s the whole reason verification matters more than negotiation. You can haggle 10% off a price. You can’t haggle your way out of a number that was never real.

I learned a version of this with real estate. A rental’s listing always shows the rent. It rarely shows the vacancy, the repairs or the property tax reassessment. It’s part of why I eventually sold my rental property to buy index funds. The number on the sheet and the number in your bank account are different animals.

How the water bill check works

A wash cycle commonly uses about 12 to 25 gallons, depending on the machine’s size and efficiency. So you work backward:

1. Take the monthly water use. Many utilities bill in CCF, and one CCF is about 748 gallons.
2. Subtract water that didn’t go through a self-serve washer: restrooms, wash-and-fold, leaks.
3. Divide by the average gallons per cycle for that store’s machine mix.
4. Multiply by the average price per wash.
5. Add dryer revenue, which the Coin Laundry Association says typically runs 40% to 60% of washer revenue.

Let me run a hypothetical store:

• 45,000 gallons a month of self-serve water
• 18 gallons per cycle on average, so 2,500 cycles
• $4.50 average wash price, so $11,250 in wash revenue
• Dryers at 40% to 60% of that: $4,500 to $6,750
• Water says the store does about $15,750 to $18,000 a month

Now say the seller claims $22,000. That’s more than 20% above the top of what the water supports. Many brokers and lenders treat a gap above roughly 15% to 20% as a red flag. It doesn’t prove anyone is lying. Maybe the machine mix is different than I assumed, or prices went up recently. But it means the seller owes you an explanation with records, not a shrug.

And watch the history, not just the latest month. A store that suddenly uses a lot more water right before listing might have had someone running empty cycles. Two years of bills makes that obvious.

What a wrong multiple does to your life

Here’s the part that makes this personal. Let’s say the verified earnings are $70,000 a year, and you buy with an SBA loan: 10% down from your own money, the rest over 10 years at an assumed 10.5%. Watch what the multiple does to what’s left for you:

Multiple paid	Price	Yearly loan payments	Left before repairs and your time
3.0x	$210,000	about $30,600	about $39,400
3.5x	$245,000	about $35,700	about $34,300
4.0x	$280,000	about $40,800	about $29,200
4.5x	$315,000	about $45,900	about $24,100

Same store. Same customers. Paying 4.5x instead of 3x cuts what’s left for you by almost 40%. And that leftover still has to cover the dryer that dies in winter and pay you for the hours you’ll put in. When people say a business “didn’t work out,” this table is often what happened. The business was fine. The price wasn’t.

The other two witnesses

The water bill tells you about the past. Two other things tell you about the future.

The lease. Most laundromats rent their space, which means the lease is really the asset. Lenders generally want at least 10 years left, counting renewal options. I’d also want to know whether it can be assigned to me, how the rent escalates, whether the landlord can put another laundry in the same center, and whether there’s a demolition or relocation clause hiding in the back pages.

The machines. The CLA estimates front-load washers and dryers last roughly 10 to 15 years and top-loaders 5 to 8. Pull the serial numbers, have the local distributor date them, and put a price on the replacements coming in the next five years. That money is part of the purchase price whether it’s on the contract or not.

If you want the full list, including tax returns, bank deposits and card-system reports, there’s a step-by-step checklist for buying an existing laundromat.

Walking away is a skill

The hardest part of buying a business isn’t the math. It’s letting go of the one you’ve already imagined owning.

Picture Tanya, an illustrative buyer, not a real person. She spends two months on her first laundromat. She’s picked out new signage in her head. Then the water bills come in and support about three-quarters of the claimed revenue, and the lease has five years left. The seller gets defensive. She walks, and it stings.

Her second store is uglier: old top-loaders, a stained floor, coin-only. But the water matches the books within a few percent, the lease has 14 years with options, and the seller will carry a small note. She buys it near 3x, replaces the worst machines, adds card readers and an ATM, and runs it cleanly. The boring store with honest numbers turns out to be the good business. It usually is.

I think walking away is one of the most underrated freedom skills there is. Every “no” to a bad deal keeps your savings intact for the right one. I’ve written about building a financial freedom runway, and this is exactly what that runway is for: the ability to wait.

Where good deals come from

A lot of the best small laundromats never get listed. A retiring owner sells to someone who wrote a letter at the right time.

One small exercise if you’re serious: pick one laundromat near you this week, sit in it for an hour on a Saturday, and count the cycles. You’ll learn more about the business in that hour than in a week of listings.
