Why Lenders Love Car Wash Deals
Modern express exterior car washes operate at 40-60% EBITDA margins with significant recurring revenue from monthly unlimited-wash memberships. Lenders treat strong-performing express tunnels almost like quasi-real-estate — predictable cash flow, low operating overhead, and growing aftermarket valuations. The 504 program is the dominant tool for car wash real estate, with 7(a) added for equipment, membership marketing, and working capital.

Express Tunnel vs Other Formats
The car wash industry has consolidated around the express exterior tunnel format, which now dominates new construction and acquisitions. Tunnels offer the strongest unit economics, fastest throughput (90-120 cars/hour at peak), and the membership-revenue model that lenders prize. In-bay automatic and self-serve formats can still be SBA-financed but rarely command tunnel-level lender appetite.
Acquisition vs Ground-Up
Acquiring an established express tunnel with a proven membership base is the cleanest SBA deal. Lenders evaluate trailing 12-month revenue, membership count, average ticket, and retention rates. Ground-up construction requires more borrower equity (often 20%+), a robust traffic study, and a credible projection of how fast the membership base will ramp.
Equipment & Technology
Modern tunnel equipment from PECO, Sonny's, Tommy's, and others runs $400K to $1M+ depending on length and feature set. RFID payment, license-plate-recognition entry, and modern POS systems are now table stakes — lenders viewing your business plan will expect them. All of these are SBA-eligible under either 504 (if part of construction) or 7(a) (standalone equipment).
