From SBA-financed asset purchases to PE all-cash roll-ups, here's how buyers and sellers in the car wash industry negotiate and close deals in the $1M–$5M revenue range.
Car wash acquisitions in the lower middle market typically fall into three deal structures: SBA-financed asset purchases with a seller note, all-cash strategic acquisitions at premium multiples, and seller-financed deals with earnouts tied to membership growth. The right structure depends on the buyer's capitalization, the site's equipment age and membership base size, whether real estate is included, and whether the seller needs a clean exit or is willing to stay tied to future performance. EBITDA multiples in this space range from 4x to 7x, with high-membership express tunnel sites commanding the top of the range. Understanding how each structure works — and its tradeoffs — is essential before entering a letter of intent on any car wash transaction.

The most common structure for first-time buyers and owner-operators acquiring a single car wash location. The buyer uses an SBA 7(a) loan to finance 80–85% of the purchase price, with the seller carrying a subordinated note for 10–15% and the buyer contributing 10% equity. The deal is structured as an asset purchase, allowing the buyer to step up the tax basis of equipment and goodwill. SBA lenders will scrutinize equipment age, environmental history, and membership program cash flow when underwriting.
Pros
Cons
Best for: First-time buyers acquiring a single express tunnel or in-bay automatic car wash with clean financials, documented membership revenue, and equipment under 7 years old
All-Cash Strategic or PE Acquisition
Regional car wash operators executing buy-and-build strategies and private equity-backed platforms frequently acquire high-performing sites with all-cash offers. These buyers move faster, require less seller documentation, and can close in 30–45 days. They typically pay at the top of the multiple range — 6x to 7x EBITDA — for sites with 1,000+ active unlimited wash members, modern tunnel equipment, and owned or long-term leased real estate. The speed and certainty of close justify the premium price.
Pros
Cons
Best for: High-performing express tunnel car washes with 750+ active unlimited members, EBITDA above $500K, modern equipment, and favorable real estate terms in high-growth suburban markets
Seller-Financed Deal with Membership Earnout
In situations where the seller's membership base is growing but not yet mature, or where the buyer cannot fully qualify for SBA financing, a seller-financed structure with an earnout tied to membership milestones can bridge the valuation gap. The buyer pays a base price reflecting current EBITDA, with additional earnout payments triggered if the membership base exceeds agreed thresholds — for example, reaching 800 active members within 18 months. The seller typically holds a first or second lien on business assets during the earnout period.
Pros
Cons
Best for: Car wash businesses with a growing but not yet stabilized membership program, or transactions where the buyer and seller disagree on valuation due to recent operational improvements not yet fully reflected in trailing EBITDA

Car wash businesses in the $1M–$5M revenue range typically trade at 4x to 7x EBITDA. Sites with 500+ active unlimited wash members, modern tunnel equipment under 5 years old, and owned real estate or long-term ground leases command the upper end of the range — often 6x to 7x. Sites with aging equipment, minimal membership programs, or short lease terms will trade closer to 4x to 5x. PE-backed strategic buyers regularly pay at or above 6x for high-quality membership-driven express tunnel locations in growth markets.
Yes, car washes are SBA-eligible businesses and are a well-understood asset class among SBA 7(a) lenders. The SBA will typically finance 80–85% of the purchase price with a 10-year term. Key underwriting requirements include 3 years of tax returns, a third-party equipment appraisal, a lease with sufficient remaining term, a clean environmental history, and demonstrated cash flow capable of covering debt service with at least a 1.25x DSCR. Membership program revenue with documented recurring cash flow significantly strengthens SBA loan approval odds.
Real estate is handled one of three ways: the real estate is included in the business sale at a blended price, the real estate is sold separately or retained by the seller under a long-term ground lease, or the site is already on a third-party ground lease that transfers to the buyer. Owned real estate adds significant value and expands the buyer pool because it eliminates lease renewal risk and often allows the buyer to finance real estate separately through an SBA 504 loan at favorable terms. Ground leases are acceptable to most buyers and lenders if the remaining term plus renewal options provides at least 15–20 years of remaining tenure.
In SBA-financed car wash transactions, the seller note typically represents 10–15% of the purchase price, carries an interest rate of 5–7%, and is structured on a 24–60 month repayment term. SBA lenders will require the seller note to be on standby — meaning interest-only or fully deferred — for the first 12–24 months of the SBA loan. The seller note is subordinated to the SBA lien, so the seller must be comfortable accepting repayment risk. Sellers who agree to carry a note are viewed favorably by SBA lenders as a signal of confidence in the business's continued cash flow.
An earnout is a contingent payment structure where a portion of the purchase price is paid post-close only if the business hits agreed performance targets — most commonly, active unlimited wash membership count milestones. Earnouts make sense when the seller's membership base is new or rapidly growing and the buyer is unwilling to pay for projected membership at close. A typical car wash earnout might be structured as $150K–$300K paid in two tranches if membership reaches 700 then 900 active members within 12 and 24 months. Earnout agreements must precisely define how active members are counted, how disputes are resolved, and what operational restrictions apply to the buyer during the earnout period.
Purchase price allocation in a car wash asset purchase matters significantly for both buyer and seller tax outcomes. Buyers prefer to allocate more value to depreciable tangible assets like tunnel equipment, conveyor systems, and dryers — which can be depreciated over 5–7 years — and less to goodwill and covenant not to compete, which are amortized over 15 years. Sellers prefer the opposite, as goodwill typically receives capital gains treatment while equipment allocation triggers depreciation recapture taxed as ordinary income. The allocation must be agreed upon and filed consistently by both parties using IRS Form 8594. Engaging a CPA with car wash transaction experience before signing the purchase agreement is strongly recommended.
