Worked Example: SBA 7(a) Flex-Serve Car Wash Feasibility Study in Texas
A worked example of the feasibility study a lender would read for a car wash project in Texas, financed with an SBA 7(a) loan.
What SBA's own loan files show about SBA 7(a) lending to car wash projects in Texas, and what a feasibility study for an SBA 7(a) loan there has to test.
A median loan of $2.2 million stands at 2.73x the nationwide 7(a) figure for car washes, and that ratio defines this cell. Texas holds 336 approvals between FY2017 and FY2026, worth $728.4 million, and ranks second among states for the class by number of loans; car wash is 12 of 39 among Texas asset classes. The middle half of loans runs from $507,500 to $3.4 million. Franchising is rare, at 3.3% of loans, so this is an owner-operator, land-and-equipment business.
Express tunnels are built on a purchased site with long conveyors, water reclaim and vacuum systems, which is why the loan is a multiple of what other states record. The code mixes car and truck washes, including mobile washes, so a low-cost mobile operation sits in the same statistics as a large tunnel. The median therefore sits between two very different businesses, and a borrower should know which one is being compared.
Metro City Bank has 47 loans and Celtic Bank Corporation 35, then The Huntington National Bank 20, Commonwealth Business Bank 13 and Prosperity Bank 12. These are the holders SBA reports and nothing here says what any of them requires. Tarrant County has 60 loans, Harris 58, Dallas 39, Collin 26 and Denton 19, so the Dallas and Fort Worth area leads over Houston. Volume peaked near 47 loans in FY2019 and FY2021, and fell to 21 in FY2026, with FY2024 dollars at $42.4 million.
Cancellation reached 11.2% for approvals from FY2017 to FY2024 and 11.9% when undisbursed loans are counted. Charge-offs are low: of 189 loans that funded in FY2017 through FY2021, 1.1% have been written off, and the identical 1.1% fell inside five years. Because open loans can still fail, these are floors only.
A study must prove traffic: vehicles per day on the road, the share that stop, and the competing tunnels within a short drive, because express washes are decided by access and visibility. It should test the membership model, average ticket, chemical, water and power costs, and the land price and site work that drive a loan near $2.2 million. Debt service coverage has to survive a wet season and a new competitor across the road. An appraiser will value the site as an operating business, so the revenue forecast must be one that can be tested.
| Loans approved, FY2017 to FY2026 | 336 |
|---|---|
| Gross dollars approved | $728.4 million |
| Median loan | $2.2 million |
| Middle half of loans, from | $507,500 |
| Middle half of loans, to | $3.4 million |
| Franchise share of loans | 3.3% |
| Rank among states for SBA 7(a) car wash loans, by number of loans | 2 |
| Rank of car wash among classes in Texas | 12 of 39 |
| Median loan against the national SBA 7(a) median for the class | 2.73x |
| Cancelled after approval, FY2017 to FY2024 approvals (a floor) | 11.2% |
|---|---|
| The same, counting loans still undisbursed as cancelled (a ceiling) | 11.9% |
| Charged off to date, FY2017 to FY2021 disbursed loans (a floor) | 1.1% |
| Charged off within five years of approval | 1.1% |
| Loans in that cohort | 189 |
Both rates are floors. SBA withholds the status of open loans, so a loan counts as charged off only once SBA reports it; a rate needs at least 30 loans in its cohort and is otherwise not reported.
