At first glance, this week's listing looks like someone lost their mind. A car wash business asking $13.5 million on $930,000 of cash flow. That's a 14.5x multiple, roughly triple what a business this size should command.

Except it's not crazy at all. Once you understand what's actually inside that price, you'll understand one of the most expensive mistakes an owner can make: confusing the value of their business with the value of the building it sits in.

Let's break it down.

The Listing

The 14.5x multiple is an illusion. Here's why.

If you divide the asking price ($13.5M) by the cash flow ($930K), you get 14.5x, a number that would only make sense for a fast-growing tech company, not a car wash.

But look at the line most people skim past: $9 million of that asking price is real estate. The seller owns the land and buildings, and they're included in the deal.

So you have to split the price in two:

Now redo the math on the business alone: $4.5M ÷ $930K SDE ≈ 4.8x. On EBITDA, about 5.3x. Premium for a car wash, but entirely reasonable for a two-location platform with recurring membership revenue.

The 14.5x was never real. It was a business multiple stapled to a price that's mostly property.

The universal lesson #1: never judge a multiple until you've stripped out the real estate. A price that includes the building tells you almost nothing about what the business is worth.

Now the deeper trap and this one catches even experienced buyers.

When a business owns its own building, it doesn't pay rent. And that means the cash flow looks better than it really is.

Think about it: this car wash's $850K EBITDA was earned while paying zero rent, because the owner owns the property. But a buyer financing $9M of real estate has a very real cost with a mortgage on $9M at today's rates is easily $600K+ per year in interest alone.

So you cannot both:

If you charged this business a fair market rent for the property it occupies, that $850K EBITDA would shrink dramatically. The cash flow and the real estate value are partly the same money, counted twice. Sorting that out is the single most important piece of diligence in any deal where the seller owns the dirt.

The universal lesson #2: owning your real estate flatters your cash flow. To know what your business truly earns, you have to charge it market rent, even if you pay that rent to yourself.

What's genuinely valuable here.

Credit where it's due: the listing highlights membership offerings and commercial/fleet accounts. That's recurring, predictable revenue and as we covered in a recent issue, durable revenue is what earns a premium multiple. That recurring base is the real reason this business can justify ~5x rather than the 2–3x a transactional, walk-up-only car wash might fetch.

Now turn it on your own business.

This one is specifically for the many owners who own their buildings such as manufacturers, medical practices, restaurants, shops, anyone with their own four walls:

You don't own one asset. You own two. A business, and a piece of real estate. And their values are completely separate.

Ask yourself:

The owners who get clean, premium exits know exactly what each asset is worth independently. The ones who get surprised at the closing table are the ones who bundled them together in their head and never ran the numbers apart.
