How to buy a car wash
Start with the kind of wash you can actually operate. Then verify the revenue, walk the property, budget the work, and make an offer the existing business can support.

1. Choose the format you can operate
Self-serve washes sell time at the bay. In-bay automatics sell a wash package one car at a time. Tunnels move cars through a conveyor and introduce different labor, maintenance, and stacking demands. Visit competing sites at different times and watch how cars enter, wait, and exit before judging a location from a listing.
2. Build a deal budget beyond the purchase price
Separate the acquisition from immediate repairs, closing costs, and the reserve you need for the first months. For a leasehold, review the remaining term, renewal options, assignment rights, and who pays for major repairs. A cheap wash can be expensive if a roof, electrical panel, or automatic needs replacement before you reopen.
3. Rebuild revenue from source records
Ask for monthly records and reconcile card deposits and processor reports to bank activity. Review cash collection logs separately. Use water usage, automatic cycle counts, and site observations as cross-checks; none proves sales by itself. Keep unexplained differences visible instead of averaging them away.
4. Underwrite the wash as it runs today
Six bays at $1,000 per bay per week over 48 productive weeks is $288,000 in annual gross bay sales. That is an illustration with four weeks excluded, not a forecast or profit. Then deduct the operating costs you can document, budget repairs and reserves, and test whether a weaker year can still cover debt payments. Keep future card adoption or price increases in a separate upside case.
5. Make the offer conditional on the facts you still need
List the records, inspections, financing, and other conditions you need to resolve before closing. Walk the site with an equipment technician and have your advisers review the contract and property records. Put a dollar amount and a date on material repairs, then decide whether to renegotiate, proceed, or walk.
6. Plan the first day before you close
At Indian School, we got the keys ahead of the deed recording. That gave us time to learn the equipment, but the key handoff and the ownership transfer were separate milestones. Know who controls utilities, merchant processing, keys, alarm codes, and collections at each stage. Test a sale at each payment type and confirm where it settles.

Put it to work on a deal
The course walks through underwriting, financing, and closing with templates. For a deal you are evaluating now, choose one to three hours of consulting and arrange the time privately after purchase.
