Why laundromats are the most-mythologized 'passive' business
The myth: $500K all-cash, $200K/year, owner shows up Sundays to collect quarters. The reality: even well-run laundromats need an owner for vendor management, equipment troubleshooting, attendant supervision, lease renegotiation, and capital reinvestment. True semi-absentee is 10–15 hr/week, not zero.
The water-bill validation that catches 80% of scams
A washer uses 20–40 gallons of water per turn. If the seller claims 4 turns/day across 30 washers, that's 2,400–4,800 gallons/day. The water bill must back it up. If a seller can't produce 12 months of actual utility bills (water + gas + electric), assume revenue is overstated by 30–50% and re-price the deal.
- • Get utility bills for 12 months from the meter (water dept lookup), not the seller's spreadsheet.
- • Get the coin/card collection records, not just deposits.
- • Get the lease — and the lease's remaining term. <10 years left is a major red flag.
- • Sit in the store every day for a week before closing.
Buying vs building
Buying an existing mat is typically 2.5–4× SDE plus equipment value — $300–800K for a typical 30/30 unit. Building new is $500K–1.2M and takes 4–6 months of zero revenue before opening. Most first-time operators should buy, not build — the ramp risk of greenfield is brutal.

How much do laundromats make?
A typical 30/30 unit in a decent market does $250–500K annual revenue with 20–35% margin = $50–175K owner cash flow. Strong urban units with wash & fold add-on can hit $700K+ revenue and $200K+ cash flow. Run your specific numbers above.
How much does it cost to open a laundromat?
Buying an existing laundromat: $200–800K. Building new: $500K–1.2M (equipment $250–500K, build-out $150–400K, working capital $50–100K). SBA 7(a) financeable with 15% down on either path.
Are laundromats really passive income?
Compared to most businesses, yes — 10–15 owner hours/week is realistic with an attendant model. But 'passive' doesn't mean zero — equipment breaks, attendants quit, lease renewals happen. Plan to be on-call. True hands-off needs a manager and 3+ units.
What's the failure rate of laundromats?
Roughly 5% over 5 years per Coin Laundry Association data — one of the lowest in small business. Most failures come from undercapitalized buyouts at inflated multiples (seller hid utility costs), not fundamental business risk.
Wash & fold or self-serve only?
Wash & fold (you wash for the customer at $1.50–2.50/lb) typically adds 30–80% to revenue and pushes margin to 30%+, but requires staff and a counter operation. Self-serve only is more 'passive' but caps your ceiling. Most profitable mats today are hybrid.
