The short answer: A small self-serve wash can sell under $1M (median car wash sale ~$857,500); a performing express tunnel with real estate commonly runs $3M, $15M+. Express businesses trade at 5×, 8× EBITDA, and the land is valued separately (~6.3% cap). With an SBA loan you need a 10% injection, as little as ~$75K on a $1.5M deal, and real-estate deals use SBA 504 or sale-leaseback. Run it in the valuation calculator.
What car washes actually cost, by model
| Model | Typical acquisition price | What you're buying |
|---|---|---|
| Self-serve / in-bay automatic | $200K, $1M | Small operation, often leased site |
| Median car wash (all types) | ~$857,500 | BizBuySell median sale price |
| Express tunnel (business only) | $2M, $8M | 5×, 8× EBITDA, memberships |
| Express tunnel + real estate | $3M, $15M+ | Land, building, and membership base |
The high floor on express prices comes partly from construction economics: a single express tunnel alone, before land, costs $2M, $10M+ depending on the region. That replacement cost anchors what an existing, cash-flowing tunnel can command. See the playbook for how the three models differ.
How the price is set: EBITDA and the land
Express washes price on EBITDA × a multiple, plus the separately-valued real estate. Membership penetration moves the multiple most:
| Multiple | Business value | When it applies |
|---|---|---|
| 5× EBITDA | $4,000,000 | Weak memberships, high local saturation |
| 6.5× EBITDA | $5,200,000 | Solid site, decent membership base |
| 8×+ EBITDA | $6,400,000+ | 40%+ membership penetration, clean capex |
Then add the real estate, valued at roughly a 6.3% cap rate on the property's net rent. See the live figure on car wash multiples.
You're buying two assets at once: a subscription business and a piece of commercial real estate. Price and finance them as two things, because that's how the market values them.
Why real estate changes everything
Unlike a laundromat or a trade, a car wash is a real-estate-heavy business. That's a feature, not a bug:
- Longer loan term. Including real estate lets the SBA term stretch to 25 years, sharply lowering the annual payment and improving your DSCR.
- Equity you build. Every payment builds ownership in appreciating commercial land.
- Sale-leaseback optionality. You can later sell the land to an investor at a ~6.3% cap and lease it back, freeing capital.
The down payment and full capital stack
| Source / use | Amount | % of price |
|---|---|---|
| SBA 7(a) / 504 loan (25-yr with RE) | $1,350,000 | 90% |
| Your cash injection | $75,000 | 5% |
| Seller note (full standby) | $75,000 | 5% |
| Purchase price | $1,500,000 | 100% |
| + Est. closing costs & fees (financed) | ~$45,000 | |
| + Equipment / retunnel reserve | $50K, $150K |
Real "cash to close" is your ~$75,000 injection plus a reserve for equipment, not the full $1.5M. Larger express deals often blend SBA financing with conventional real-estate debt or a sale-leaseback. The loan is sized to a DSCR of ~1.15×, 1.25×.
Underwrite membership, not the peak
The fastest way to overpay is to capitalize a membership base at its high-water mark. Buy on verified, current members net of the ~7.6% monthly churn, and stress the number against local saturation. (Rinsed; MMCG Invest)
Costs buyers forget
- Retunnel / equipment capex. Aging conveyors, blowers, and reclaim systems are large near-term costs.
- Environmental compliance. Reclaim upgrades or discharge-permit fixes, verify before closing.
- SBA & closing fees, usually financed.
- Real-estate diligence. Appraisal, environmental Phase I, survey.
- Membership-system & marketing to grow penetration post-close.

Frequently asked questions
Small self-serve washes can sell under $1M (median ~$857,500). A performing express tunnel with real estate commonly runs $3M, $15M+ because land, building, and memberships are all in the deal. See car wash multiples.
You usually buy the real estate too, and the business trades at 5×, 8× EBITDA on recurring memberships and PE demand. A single express tunnel alone costs $2M, $10M to build before land, setting a high floor on prices.
An SBA loan needs a 10% injection, and up to half can be a standby seller note, as little as ~$75,000 on a $1.5M deal. Real-estate deals also use SBA 504 and sale-leaseback structures.
Usually yes, or control it with a long lease. The land is valued separately (~6.3% cap) and is a major part of the deal. Owning builds equity, enables a 25-year SBA term, and can later be monetized via sale-leaseback.
