Car wash financing has been one of the most active and competitive specialty CRE lending markets since the express tunnel boom of 2018 to 2022. Express car wash chains expanded aggressively under private equity sponsorship (Mister Car Wash, Driven Brands, Whistle Express, Mammoth Holdings, Tommy's Express, Take 5, Splash, Quick Quack, Zips, ModWash, others) and an active SBA owner-operator market emerged alongside. The lender ecosystem includes specialty car wash banks, SBA 504 and 7(a) for individual operators, conventional bank balance sheet for established multi-location operators, and substantial private credit appetite for both ground-up development and roll-up consolidation strategies.

The express tunnel boom created an active specialty lender bench focused on the asset class, with several banks (Live Oak, M&T, Wintrust, BMO, others) and specialty private credit funds active in the market.
Pricing is indicative and reflects active CLS CRE quote pipeline as of April 2026. Actual pricing depends on property condition, sponsor profile, deal size, and market dynamics.
Single-location express tunnel ground-up projects typically run $4M to $8M total project including land, site work, tunnel, equipment, and reserves. A typical 130-foot to 180-foot tunnel with 8 to 12 vacuum positions, water reclamation, and modern PLC tunnel control runs $2M to $4M in equipment alone. Land cost varies enormously by market: a Sun Belt site might cost $800K to $1.5M, while a coastal California site might cost $3M to $5M.
Multi-location operator acquisitions and portfolio refinances run $10M to $50M for regional operators with 5 to 25 locations. National consolidators (Mister Car Wash, Driven Brands, others) target $50M+ portfolio acquisitions. Trevor's CLS CRE pipeline focuses primarily on the $5M to $25M owner-operator and regional segment.
Operating revenue is dominated by membership monthly recurring revenue (MRR) at modern express tunnel facilities, with retail per-wash revenue and add-on services (tire shine, undercarriage spray, hot wax) as supplements. Lenders evaluate membership penetration, churn, retention, and average revenue per member. Stabilized express tunnel facilities operating at 60 to 75 percent membership conversion are considered fully stabilized.
Car wash underwriting evaluates the property, the equipment, and the operating business with significant focus on membership penetration and lifetime customer value. The express tunnel model has standardized underwriting metrics that lenders apply consistently across the asset class.
Car wash transactions look straightforward on the surface but have specific failure modes around membership ramp, equipment lifecycle, and competitive saturation that have caught many sponsors during the post-2022 market normalization.
On a $5.8M ground-up express car wash construction in a Texas Sun Belt market, the sponsor was a second-time car wash operator with one stabilized location operating at 68 percent membership penetration. The project included $1.2M for land (a 1.4 acre commercial pad with 32,000 vehicle per day traffic count), $3.4M for tunnel construction and equipment (a 165-foot tunnel with 12 vacuum positions, water reclamation, and modern PLC), $700K for site work and stormwater, $300K for FF&E and signage, and $200K for working capital and reserves. SBA 504 was used at 80 percent LTC due to special-purpose classification, structured as a 50 percent bank first lien at 7.45 percent and a 30 percent CDC second lien at 5.85 percent fixed. SBA 7(a) was used for working capital at $400K. Construction took 11 months from groundbreaking to grand opening. Membership ramp came in slightly behind pro forma, hitting 52 percent penetration at month 18 versus the 60 percent base case, but operating cash flow was supported by stronger-than-expected retail wash volume. The deal stabilized at month 30 with 67 percent membership penetration, in line with the lender's stabilization underwriting.

Car wash financing has matured rapidly since 2018. The lender bench is deep, the underwriting metrics are standardized, and the sponsors who succeed are the ones who plan for 24 to 36 month membership ramp instead of the 18-month pro formas everyone was running pre-2022.
