Financing Express Tunnels and Membership Car Washes
Recurring wash memberships changed the economics of this business. Lenders who get the model will fund equipment and real estate together. We know who they are.
How Membership Revenue Reshaped Car Wash Lending
The express tunnel boom turned car washes into recurring-revenue businesses. Unlimited monthly wash plans smooth out cash flow, and lenders who understand the model will finance the real estate, the tunnel equipment, and the site work in one structure. The catch is that a car wash blends heavy equipment with real estate, so underwriting has to account for both the property value and the depreciating conveyor, blowers, and water reclaim systems. CapitalAx works with SBA 504 and 7(a) lenders that fund car washes regularly, plus conventional banks and private capital for multi-site operators. Deals range from single express tunnels to portfolios rolling up independent locations. Membership counts, cars washed per day, and labor efficiency drive the numbers, and the strongest operators pair a high-throughput tunnel with a large recurring membership base that keeps revenue steady through slow weather.

Why CapitalAx
Car washes fall in an awkward gap: too equipment-heavy for many real estate lenders and too property-driven for pure equipment financers. CapitalAx works with SBA 504 and 7(a) lenders who fund express tunnels regularly, plus banks and private capital for multi-site roll-ups. We know how to present membership revenue, throughput, and the split between real estate and equipment so lenders can size the deal correctly and fund both sides in one structure.
Frequently Asked Questions
Why is car wash financing structured around both real estate and equipment?
A car wash is part property and part machine. The land and building hold long-term value, while the tunnel conveyor, blowers, dryers, and water reclaim systems depreciate and eventually need replacement. Lenders size the loan against both, often using SBA 504 to fund the real estate and equipment together at a fixed rate. Getting the allocation right matters because it affects the term and the collateral coverage.
How do lenders view membership revenue in underwriting?
Recurring wash memberships are a major positive. A large base of monthly members creates predictable cash flow that holds up during slow weather, when single-wash traffic drops. Lenders look at total active members, monthly churn, and average revenue per member alongside cars washed per day. A site with strong membership penetration underwrites more favorably than one that relies on one-time pay-as-you-go volume.
Can I use an SBA loan to build a new express tunnel?
Yes. SBA 504 is a common fit for ground-up express tunnel projects because it funds the land, building, and heavy equipment together with a low down payment and a long fixed-rate term. SBA 7(a) works for acquisitions and situations that need working capital folded in. You have to operate the wash yourself, since SBA financing is for owner-operators rather than passive investors.
