🎯 The business: buying an existing, under-loved laundromat in a renter-heavy neighborhood and running it better — card payments, cleanliness, longer hours, wash-and-fold. Unlike everything above, you are not building demand; you are buying demand that already exists and is verifiable in the water bill.

Demand is essential and recession-tilted (more renters, fewer in-unit machines in hard times), no inventory spoils, no receivables age, and the customer serves themselves. The catch is equally simple: everything true about the business is true of the location and the lease, and both are fixed the day you buy. This plan is 80% diligence, 20% operations — the inverse of every plan above.

First month: education. Tour ten laundromats as a customer with a notebook: machine ages, prices, cleanliness, traffic at 7pm. The owner forums are candid and free. Two SCORE sessions with anyone who has owned coin-op. Get pre-qualified for an SBA 7(a) — laundromats are a lender-familiar asset class, typically 10–20% down.

Second month: deal flow. BizBuySell, yes, but also the equipment distributors’ reps — they service every mat in the region and know which owners are tired years before a listing appears. Analyze on verified utility bills: water consumption converts to turns-per-day arithmetic the seller cannot embellish. Typical pricing runs 3.5–5× verified yearly net.

Closing months: diligence with teeth — collection audits where you personally watch weeks of revenue, a distributor tech’s inspection of machine ages, and above all the lease: ten years with options or no deal, because a laundromat cannot move. Then the ninety-day facelift that reliably lifts revenue: card systems (expect “found” revenue versus coins), lighting, paint, cameras, and wash-and-fold at $1.75–2.25 a pound.

LLC → SBA pre-qualification → purchase agreement and lease assignment (this is the document; pay the lawyer) → license and utility transfers → insurance → seller’s permit and simple POS when wash-and-fold launches. Building new instead of buying is a different, harder book: utility hookups and permits for a new laundry are notoriously slow and expensive. Buy the boring one that already hums.

A mat grossing $20k a month typically runs 65–70% expenses — rent, water, gas, electric, an attendant, machine repair — netting $6–7k, most of it while you are elsewhere. Wash-and-fold is the growth lever: a hundred pounds a day at $2 a pound adds roughly $4k a month at half margin, and apartment dwellers and Airbnb hosts keep it steady. Machines last ten to fifteen years; the owners who get wiped out are the ones who spent the replacement reserve. A thousand a month into that reserve is a bill, not a choice.

Walk when the collection audit doesn’t match the seller’s story — no negotiation, walk; the water bill was your friend and the books were not. Walk from any lease under ten years, or rent above ~30% of revenue. After close: reviews to 4.5 within a quarter (most mats have three stars and no photos — the bar is on the floor), wash-and-fold at fifty pounds a day by month six, net up a quarter on the seller’s baseline within the year — then, and only then, start looking at mat number two.

“Semi-passive” gets misread as passive; year one runs fifteen hours a week of fixing, learning and systematizing before it earns the reputation. Water and sewer rates rise without asking your opinion — the 24 months of bills you analyzed are also your forecast. And machines break in clusters; the reserve is the business. Owners who treat the mat like the vending machine it appears to be sell it, tired, to the next person who reads a chapter like this one — be the buyer, not the seller, in that story.
