How to buy a gas station: a step-by-step guide for first-time buyers

Fuel brings the cars onto the lot, and it dominates the revenue line. It doesn't dominate the profit. Across the U.S. convenience industry in 2025, according to the NACS State of the Industry report:

Most of the profit came from inside the store. That changes how you read a deal. A station with impressive gallons and a tired store is a weaker business than its revenue suggests, and a seller who only wants to talk about fuel volume is steering you away from the line that matters most. Judge the store as a business in its own right: inside sales, margin by category, and whether the lottery, tobacco, and food income will survive the sale.

1. 1

   Decide what you're actually buying

   Gas station deals come in different shapes, and each shape is priced and financed differently. Are you buying the business only, on a lease, or the business plus the land and building? Is the station branded (Shell, BP, Marathon and the like) under a dealer supply agreement, or unbranded with a free choice of supplier? And who owns the tanks, pumps, and canopy: the seller, the landlord, or the fuel supplier? Tank ownership decides who answers for leaks and compliance, so get it in writing before anything else.

2. 2

   Get the real financials, not the listing summary

   Ask for three years of federal tax returns, the full P&Ls, 12 months of business bank statements, the fuel supplier's delivery records, and the state lottery commission statements. Tax returns are the anchor: sellers inflate spreadsheets far more readily than the figures they reported to the IRS. Your lender will run the same test. Under current SBA rules, the lender must check the financials behind the business valuation against the seller's IRS transcripts, so it's better that you find any gap first.

   Rebuild the earnings and check the gallons

   A station is priced on SDE (seller's discretionary earnings): net profit plus the owner's salary and genuine one-time or personal expenses. Rebuild it yourself instead of accepting the seller's figure, because every padded add-back gets multiplied into the price. Then test the fuel claims. The gallons on the P&L should match the supplier's delivery records, and identical round revenue month after month is a warning sign.

   Price it against real multiples

   Most gas stations sell for 2.0× to 3.5× SDE, with inventory (usually $20,000 to $60,000) added on top. A recognized brand, a long assignable lease, newer tanks, and a busy corner push a station toward the top of the range. An unbranded site, a short lease, old tanks, or falling fuel volume push it toward the bottom. If the land and building are part of the deal, they're appraised and valued separately from the business.

   Line up financing before you fall for the deal

   Many buyers finance with an SBA 7(a) loan. Talk to a lender early, because SBA rules shape the whole deal: at least 10% of the total project cost down, an independent business valuation that caps how much can be borrowed, and a cash-flow test the station's historical earnings must pass. If you agree to pay more than the valuation supports, the difference has to be covered with equity, not the loan. The table below has the rules that matter.

   Write an LOI that protects you

   The Letter of Intent sets the rules for everything that follows, and your leverage peaks before you sign it. Get a due-diligence window long enough to verify everything (typically 30 to 60 days). Make the deal contingent on financing, a clean environmental assessment, the lease assignment, the fuel brand's written consent, and the license transfers, with your deposit refundable if any of them fall through.

7. 7

   Clear the tanks and the environmental history

   This is the step that makes a gas station different from any other small business. For an SBA loan, a Phase I environmental site assessment is mandatory on every gas station, whatever the loan size, and the lender can't release the money until the tanks and equipment pass their testing requirements and anything leaking is fixed. Do the same work even without the SBA: pull the tank registration, inspection, and leak-detection records, search the EPA's ECHO database and your state's UST registry for violations and past releases, and check the tanks' age. Tanks over 20 years old are high risk, and replacement runs $100,000 to $300,000.

   Transfer the contracts, licenses, and tank duties

   Much of what keeps a station running doesn't move with the sale on its own. A branded dealer agreement typically needs the supplier's written consent; get it, and read the remaining term and any required image refresh (often $30,000 to $60,000 every 8 to 12 years). Confirm the lease can be assigned and runs long enough. Lottery, tobacco, and alcohol licenses generally need a new application or an approved transfer, depending on the state, so start early. Federal tank rules apply to you from day one: trained Class A and Class B operators within 30 days of taking over, trained Class C operators before they start, and $1 million per occurrence of financial responsibility for leaks.

   Close on a count, not a promise

   Count the merchandise inventory at closing, not weeks before, and deduct anything stale or expired. Measure the fuel in the tanks and price it at the current wholesale cost. Walk the pumps, coolers, and building one last time. Then plan the handover: under SBA rules the seller can stay on as a paid consultant for up to 24 months, which is often the cheapest training you'll ever buy.

Yes. Plenty of first-time buyers do, but expect two things. Your lender will ask about it: SBA rules require the lender to document your industry experience and who will run the station day to day. And the learning curve is real. Fuel pricing, supplier and brand relationships, tank compliance, cash handling, and age-restricted sales all land on you at once.

You can close most of that gap early. Work shifts at a station or shadow the seller before you sign an LOI. Write a transition period into the purchase agreement. Keep the experienced manager if you can. Finish your Class A and Class B operator training early, since you'll need it within 30 days of taking over anyway. For a first-timer, the register is the easy part. The hard part is knowing what to verify before you buy, which is what the nine steps above are for.

It can be. A station is a cash business with everyday demand, and at 2.0× to 3.5× SDE you're paying roughly two to three and a half years of the owner's earnings for it. The risks are specific: fuel margins that swing, environmental liability that can outlast your ownership, long operating hours, dependence on a brand or supplier contract, and open questions about long-term fuel demand for stations that live on gallons instead of the store.

So the answer comes down to the specific station. It's a good investment when the numbers are verified, the tanks are sound, the lease and brand agreement transfer, and the store earns its keep. It's a bad one when you pay for the seller's story.

1. Search and screening

   Varies widely

   Listings, a first look at the numbers, the early no's

2. Letter of Intent

   Negotiated

   Price, contingencies, the due-diligence window

3. Due diligence

   Typically 30 to 60 days

   Financial verification, Phase I, tank records, lease and brand review

4. Financing and approvals

   Runs alongside due diligence; can run past it

   SBA underwriting, valuation, brand consent, license applications

5. Closing

   One day, then the transition period

   Inventory count, fuel measurement, funding, handover

Build slack into the LOI. If the environmental report recommends a Phase II, or a license approval stalls, you want the right to extend the deadline or walk away with your deposit.

Your leverage comes from what you verify. Every documented problem is a price conversation:

• ▸Price on the SDE you verified, not the SDE in the listing. If the add-backs don't hold up, the price shouldn't either.
• ▸Old tanks or overdue tank work: ask for a lower price, a seller-paid replacement, or part of the price held in escrow.
• ▸A brand image refresh coming due: get it credited against the price.
• ▸A price above the appraisal: under SBA rules the gap has to be covered with equity rather than the loan, which gives the seller a concrete reason to meet the appraised number.
• ▸Inventory: agree in the contract that it's counted and priced at closing, not fixed weeks ahead.
• ▸Seller financing: a note on full standby can count toward half your down payment, and a seller willing to carry part of the price is a seller who believes the numbers.

Every week you stay in a deal, walking away gets more expensive. Catch the deal-breakers first, before you pay for the professionals, and long before you own the tanks.

How do I buy a gas station?

Decide exactly what you're buying (business only or with the real estate, branded or unbranded, who owns the tanks), get three years of tax returns plus bank statements and fuel-supplier records, rebuild the SDE yourself, price it at 2.0× to 3.5× SDE plus inventory, line up financing early, sign an LOI with real contingencies, clear the tanks and environmental history, transfer the brand agreement, lease, and licenses, and count the inventory at closing.

How much money do I need to buy a gas station?

With an SBA 7(a) loan, at least 10% of the total project cost for a first-time acquisition, and that minimum can't be waived. You'll need more if you agree to a price above the independent business valuation, because SBA rules require that gap to be covered with equity (your cash, or seller debt on full standby), not the loan. Inventory (usually $20,000 to $60,000) is added to the price, and you'll want cash in reserve for repairs.

Can I buy a gas station with no experience?

Yes, and many first-time buyers do. Expect your lender to ask about it, since SBA rules require the lender to document your industry experience and who will manage the station day to day. Close the gap by working shifts at a station before you buy, negotiating a seller transition period (up to 24 months as a consultant under SBA rules), keeping experienced staff, and finishing your UST operator training early.

Do I need an environmental assessment to buy a gas station?

If you use an SBA loan, yes. A Phase I environmental site assessment is mandatory on every gas-station loan regardless of the amount, followed by a Phase II if the environmental professional recommends one. Without SBA financing it's still the most important check you can run, because contamination found after closing can become your problem.

How long does it take to buy a gas station?

The due-diligence window alone is typically 30 to 60 days after the Letter of Intent, and SBA underwriting, environmental work, the fuel brand's consent, and license approvals all run alongside it. Write the right to extend into your LOI, because any one of those can run long.

Is buying a gas station a good investment?

It can be, when the numbers are verified, the tanks are sound, the lease and brand agreement transfer, and the store earns its keep. In 2025, fuel brought in 65% of U.S. convenience-industry sales but under 39% of gross profit, so most of a station's profit comes from inside the store. Judge the store as closely as the gallons.
