- Plan for a 30 to 90 day SBA close or 30 to 60 days conventional, inside a total sale timeline of 3 to 6 months from listing to funding.
- A Phase I Environmental Site Assessment to ASTM E1527-21 runs 1800 to 3500 dollars and is required for SBA fuel deals before a lender will commit.
- SBA 7(a) caps at 5 million dollars, requires a 15 percent minimum equity injection on special-purpose gas stations, and offers real estate terms up to 25 years at roughly 9 to 11.5 percent APR variable as of June 2026.
- Conventional financing typically demands 30 to 40 percent down, and many banks avoid USTs entirely because of CERCLA cleanup liability.
- Underground storage tanks drive the deal. Tank age, leak history, registration, and the Phase I result determine financeability more than the asking price.
- Fuel supply agreements, brand image obligations, and any ground lease must be reviewed and assigned during escrow, not after, because the jobber or brand can block a transfer.
Closing a gas station is not like closing a strip retail building. You are buying fuel systems, a convenience-store business, underground storage tanks, and often a fuel supply agreement all at once. Each of those layers carries its own diligence, its own paperwork, and its own way to kill a deal at the eleventh hour. A typical sale runs 3 to 6 months from listing, and the period from accepted offer to funding is where environmental liability, lender requirements, and lease terms either line up or fall apart. This guide walks the full process in order, from the letter of intent through purchase agreement, environmental and financial due diligence, financing, and the final settlement. Gas Station Trader is the fuel and C-store practice of Eagle Nest Property Group, and the sequence below reflects how these transactions actually get to the closing table.
Step 1: The Letter of Intent and Deal Structure
The letter of intent sets price, structure, and the rules of engagement before anyone spends real money. The first structural question is whether you are buying the business only, the business plus real estate, or the real estate under a lease. That choice moves valuation dramatically. Business-only deals trade at 2.5x to 4.0x EBITDA, combined operations at 4.0x to 7.0x EBITDA, and a station sold with its real estate runs around 8x EBITDA, reaching 7x to 9x in premium markets.
The LOI should name the deposit, the diligence period, the financing contingency, and who pays for the Phase I environmental assessment. It should also flag whether a fuel supply agreement or brand contract will transfer. Get these terms right here and the rest of the process is execution. Run the numbers before you sign using our gas station valuation calculator, and read our how to buy a gas station guide for the full buyer playbook.
Step 2: Purchase Agreement and Opening Escrow
Once the LOI is signed, attorneys draft the purchase agreement, which converts the deal points into binding terms. This is where you define exactly what conveys: fuel dispensers, the canopy, POS systems, the underground storage tanks, inventory, and any assignable contracts. Asset purchase is the common structure on station deals because it lets a buyer leave behind unknown liabilities, including past environmental claims.
The agreement opens escrow and starts the diligence clock. Earnest money goes hard only after the inspection and financing contingencies are satisfied. Build in enough time. SBA closings run 30 to 90 days and conventional closings run 30 to 60 days, and environmental work can extend either. The purchase agreement should also require the seller to deliver fuel volume records, since a busy urban station does 100,000 to 150,000 gallons per month against a US average near 4,000 gallons per day. Those numbers anchor every later valuation and financing conversation. See our due diligence checklist for the full document request list.
Step 3: Underground Storage Tank Diligence
Underground storage tanks decide more gas station deals than price does. Federal CERCLA liability for contamination can follow the property owner, which is why many conventional banks avoid UST sites altogether. Your tank diligence has to answer four questions: how old are the tanks, are they steel or fiberglass, is there any leak or release history, and are registrations and compliance records current with the state agency.
Pull the tank registration, line and tank tightness test results, leak detection records, and any release reports filed with the state. Steel tanks nearing the end of their service life are a financing and insurance problem even when no release has occurred. If the seller participates in a state UST cleanup fund, confirm the site is eligible and in good standing, because that fund can be the difference between a financeable deal and a walk-away. Our guides on underground storage tanks and environmental insurance cover this layer in depth.
Step 4: The Phase I Environmental Site Assessment
The Phase I ESA is the formal environmental review a lender relies on, and it is required for SBA fuel deals. A Phase I to the ASTM E1527-21 standard costs 1800 to 3500 dollars and is performed by an environmental professional who reviews historical records, regulatory databases, and the physical site for recognized environmental conditions. It does not involve soil or groundwater sampling.
If the Phase I flags a recognized environmental condition, the next step is a Phase II, which does include sampling and can take weeks and add real cost. Order the Phase I early in the diligence period. Waiting until the financing contingency is nearly closed is the single most common reason a fuel deal blows its timeline. The report has a shelf life, so coordinate the order date with your expected close so the lender does not require a costly update. Learn what assessors look for in our Phase I environmental guide.
Step 5: Financing, From Term Sheet to Commitment
Financing runs in parallel with environmental work, and the two are linked because no lender funds a fuel site without a clean or remediated Phase I. SBA 7(a) is the most common path for owner-operators. It caps at 5 million dollars, treats gas stations as special-purpose properties that require a 15 percent minimum equity injection (10 to 15 percent down), and offers real estate terms up to 25 years. As of June 2026, expect roughly 9 to 11.5 percent APR variable.
Conventional financing usually requires 30 to 40 percent down and a willing bank, which is harder to find given CERCLA exposure on USTs. Whichever path you take, the lender will order an appraisal, review the Phase I, verify fuel volumes and store margins, and underwrite the borrower. Pricing your debt service against net income matters because in-store items at 20 to 40 percent margins drive roughly 70 percent of profit even though the C-store is only about 30 percent of revenue.

Step 6: Fuel Supply Agreement and Brand Assignment
If the station carries a brand, the fuel supply agreement is a closing item that buyers underestimate. The jobber or oil company has the right to approve the new operator, and the existing contract may carry minimum volume commitments, image upgrade obligations, and a remaining term that does not match your plan. None of this transfers automatically.
During escrow, request the full supply agreement, confirm whether it assigns or must be renegotiated, and identify any branding capital the buyer must commit to after closing. A required image upgrade can add cost that should have been priced into your LOI. If you would rather not inherit the agreement, the alternative is going unbranded, which trades brand recognition and potential fuel credit terms for pricing freedom. Work the brand transfer early because a slow oil-company approval can push your close past the financing commitment expiration. Our guides on jobber fuel supply agreements and branded vs unbranded explain the tradeoffs.
Step 7: Lease Review and the Ground Lease Question
Not every gas station deal includes the dirt. When the operator leases the site, the lease becomes a deal-controlling document. Review the remaining term, renewal options, rent escalations, and the landlord consent requirement for assignment. A lender will not finance a business whose lease term is shorter than the loan amortization, so the lease often has to be extended or restructured before funding.
On NNN-structured investment deals the analysis flips. The buyer is underwriting the credit of the tenant and the strength of the lease rather than the operating business. National cap rates run about 5.6 percent with fuel and tighter for strong credit tenants, with Wawa near 4.83 to 5.20 percent and 7-Eleven near 5.00 to 5.40 percent. If the station is part of a 1031 replacement strategy, an absolute NNN lease with 15 to 20 year term is the ideal target. See our triple net lease guide and the NNN gas station listings.
Step 8: Final Walkthrough, Settlement, and Funding
The closing itself is the payoff for the diligence. In the final days, the title company clears title and resolves any liens, the lender issues final loan documents, and the parties reconcile prorations for fuel inventory, store inventory, property taxes, and fuel taxes. Inventory is usually counted the night before or the morning of closing, since fuel and merchandise values change daily.
Confirm that all transferring contracts, the brand approval, and any environmental indemnity or escrow holdback are documented before you sign. License transfers, including the fuel and tobacco permits and the UST operating permit, must be in process so the business can sell fuel the day after closing. Once documents are signed and funds are wired, escrow records the deed and releases proceeds. From there the operator takes possession and the real work of running the site begins.
