A self-serve valuation starts with verifiable collections and the cost of keeping bays usable. Bay count and reported revenue alone do not establish business value, property value or available owner cash.
Reconcile the collection process
Map coin, card, automatic-bay, vacuum and vending income to the relevant machines and records. Identify who collects cash, who records it and how deposits are checked. Obtain enough history to understand closed bays and seasonal variation.
Compare activity with refunds, faults and service records. A broken payment device can affect collections without reducing apparent site traffic. Do not infer revenue from water consumption without accounting for leaks, cleaning and the actual billing arrangement.
Budget the work and asset condition
List the owner's cleaning, collection, maintenance and customer-response duties. Estimate paid coverage if the buyer will not perform them. Low recorded payroll is not proof of passive ownership or a high margin.
Have qualified providers review pumps, heating, treatment, controls, drains and supported parts. Separate urgent work from planned replacement and optional upgrades. A larger bay count can mean more replacement exposure as well as more selling capacity.
Separate occupancy from property value
Use a consistent rent assumption for the operating business and review the lease or deed. Identify access, shared services and renewal or transfer questions. If land is included, evaluate it separately with suitable professional input and confirm that any comparison uses the same scope.
Avoid adding a property estimate to an earnings-based number that already includes real estate. Do not count a fully paid old machine as maintenance-free. The calculation should reflect continuing use and replacement needs, not only book value.
Explain the range and unresolved evidence
Define the earnings basis, proposed multiple and source of comparison. Where no usable sold-transaction evidence is available, call the multiple a scenario assumption. Show the effect of a repair, coverage or rent change rather than quoting a universal Illinois figure.

Your decision worksheet
Use these questions to identify the records and decisions that matter to this topic. Bring the open items to your conversation; detailed documents can follow through an agreed private process.
| Question to resolve | Evidence to bring | Why it matters |
|---|---|---|
| Can collections be reconstructed? | Machine reports, coin custody and deposit reconciliation. | Test paid revenue before using the seller’s annual total. |
| How many bays were usable? | Fault, closure and servicing history by machine. | Understand capacity without equating installed bays with sales. |
| Who performs the unrecorded work? | Owner cleaning, collection and response duties. | Bring replacement coverage into the buyer earnings plan. |
| What property scope supports the multiple? | Lease or deed and normalized occupancy cost. | Avoid adding land to a comparison that already includes it. |
