Watch: Buying a Gas Station in Austin: UST Liability, Fuel Margins, and the C-Store Opportunity

6 min

A gas station on the northeast side of Austin changed hands last year for $1.6 million — business and real estate combined. The fuel volume was respectable but unremarkable: 120,000 gallons per month across six dispensers. What made the deal work was the convenience store. The 2,400-square-foot c-store generated $1.8 million in annual inside sales with a 32% gross margin. The fuel was the traffic generator. The c-store was the profit center. The buyer, a multi-unit convenience store operator from Houston, understood what most first-time gas station buyers miss: the pump is the hook, the store is the money.

The Austin metro area's population growth — now approaching 2.5 million across the MSA — creates consistent fuel demand as commuters navigate corridors like I-35, Highway 183, MoPac, and the 130 Toll Road. Texas processes more fuel transactions than any state except California. But buying a gas station in Austin is one of the most complex small business acquisitions available, involving environmental liability, branded fuel contracts, real estate, and regulatory compliance that don't exist in most other industries.

## Fuel Margins Are Not What You Think

New buyers routinely overestimate fuel profitability. The gross margin on a gallon of gasoline at a typical Austin station is $0.15–$0.35 per gallon — not the retail price, just the spread between the wholesale rack price and the pump price. On 120,000 gallons per month, that generates $18,000–$42,000 in monthly gross fuel profit. After credit card processing fees (typically 2–3% of the transaction, or $0.06–$0.10 per gallon), the net fuel margin drops further.

Fuel is a volume game with razor-thin margins. A station pumping 200,000 gallons per month at $0.25 net margin generates $50,000 in monthly fuel profit. A station pumping 80,000 gallons at the same margin generates $20,000. Volume is driven by location, traffic count, competitive pricing, and the number of fueling positions. During diligence, request 24 months of gallons-pumped data by month, the wholesale fuel cost records, and the credit card processing statements. The trend matters — declining volume may signal new competition, road construction diverting traffic, or a brand issue.

Branded vs. unbranded is a critical distinction. A branded station (Shell, ExxonMobil, Chevron, Valero) operates under a fuel supply agreement with the brand. The brand provides signage, brand recognition, and sometimes equipment financing — but the fuel cost is typically $0.03–$0.08 per gallon higher than unbranded wholesale. An unbranded station buys on the open rack and controls its own pricing, but lacks brand recognition that drives highway traffic. In Austin, branded stations tend to perform better on high-traffic corridors where brand visibility matters, while unbranded stations compete effectively in neighborhoods where price sensitivity drives volume.

## The C-Store Is Where the Money Lives

The inside sales of a convenience store attached to a gas station typically generate 3–5x the gross profit of the fuel operation. A c-store doing $1.5 million in annual inside sales at a 30–35% gross margin produces $450,000–$525,000 in gross profit from the store alone. Add lottery commissions, ATM fees, car wash revenue (if applicable), and food service, and the inside operation dwarfs the fuel contribution.

Product mix drives margin. Tobacco products have high volume but thin margins (12–18%). Packaged beverages run 35–45% margin. Prepared food and fountain drinks command 55–70% margins. A station with a robust food service program — made-to-order tacos, fresh kolaches, quality coffee — captures higher spend per visit and higher margins than a station selling only prepackaged snacks.

During diligence, request the c-store's point-of-sale data broken down by product category. Analyze the gross margin by category, the sales mix, and the trend lines. A c-store where tobacco represents 50% of inside sales is vulnerable to regulatory changes and declining smoking rates. A c-store where food and beverage represent 40%+ of inside sales is building a more resilient revenue base.

## Underground Storage Tanks: The Environmental Elephant

UST (underground storage tank) liability is the single most important risk factor in any gas station acquisition. Texas has over 90,000 registered USTs, and the TCEQ maintains a database of sites with known or suspected contamination. Before you sign an LOI, check the TCEQ's Self-Reported Contamination Sites database for the property address. A site with an open contamination case may carry remediation costs ranging from $50,000 to over $1 million.

Every gas station acquisition should include a Phase I Environmental Site Assessment at minimum. If the Phase I identifies recognized environmental conditions (RECs), proceed to a Phase II assessment with soil boring and groundwater sampling. The cost of a Phase II runs $10,000–$25,000, but the information is essential. Acquiring a gas station with unidentified soil contamination can result in TCEQ enforcement action, remediation orders, and personal liability that exceeds the value of the business.

Texas has the PST (Petroleum Storage Tank) Remediation Fund, which can reimburse eligible owners for cleanup costs — but eligibility requires that the tanks were properly registered, annual fees were paid, and the contamination was reported promptly. During diligence, verify that the PST registration is current, annual fees are paid, and that no prior claims were denied.

The age of the tanks matters. Steel single-wall USTs installed before 1988 have reached or exceeded their useful life and may not have corrosion protection. Double-wall fiberglass tanks installed in the 1990s or later are more reliable but still require periodic testing. If the tanks are over 25 years old, budget $150,000–$400,000 for UST replacement. That cost should either reduce the purchase price or be covered by the seller before closing.

## Fuel Brand Contracts and Supply Agreements

If the station is branded, the fuel supply agreement is one of the most important documents in the transaction. These agreements typically run 10–20 years and include provisions covering fuel pricing, volume requirements, equipment ownership, signage requirements, and — critically — what happens upon a change of ownership.

Some branded supply agreements are assumable — the buyer steps into the existing contract terms. Others require renegotiation. Some include provisions where the brand must consent to the transfer, and that consent may come with conditions. Read the supply agreement in its entirety and have your M&A attorney review it before signing an LOI. Key questions include whether the agreement allows you to convert to a different brand at expiration, whether there are volume penalties, and who owns the dispensers and canopy (the brand may own the equipment under certain agreements, which complicates the asset allocation).

For unbranded stations, the buyer has flexibility to source fuel from any jobber or rack supplier. That flexibility is an asset — it allows you to shop for the best wholesale price and change suppliers as market conditions shift. But it also means you're responsible for your own equipment maintenance and signage without brand support.

## Real Estate: The Land Under the Pumps

Most gas stations involve real estate — either the land and building are included in the purchase price, or the operator leases from a separate landlord (often the fuel brand or a real estate investment entity). The real estate component can represent 50–70% of the total transaction value.

If real estate is included, get an independent commercial appraisal and factor the land value into your financing structure. An SBA 504 loan can finance the real estate portion at favorable rates. If you're leasing, review the lease obsessively — rent escalation, remaining term, renewal options, environmental indemnification provisions, and the landlord's right to terminate upon contamination discovery.

Gas station real estate in Austin is often located on high-traffic corners — Highway 290 and William Cannon, the intersection of Parmer and I-35, or along the 130 Toll corridor — where commercial land values have appreciated significantly. Owning the dirt under the pumps creates a dual-asset investment: a cash-flowing business and an appreciating real estate position.

(The real estate play underneath a gas station acquisition is one of the most powerful wealth-building strategies in Austin. See [Buying a Business With Real Estate in Austin: The Dual-Asset Strategy That Builds Generational Wealth](https://travisbusinessadvisors.com/articles/buy-business-with-real-estate-austin) for the full framework.)

## Regulatory and Licensing Requirements

Operating a gas station in Texas requires multiple licenses and permits. These include a TCEQ UST registration, weights and measures certification for the dispensers (inspected by the Texas Department of Agriculture), a Texas Sales and Use Tax permit, lottery retailer license (if applicable), tobacco permit, food service permits (if the c-store sells prepared food), and potentially an alcoholic beverage permit (TABC license) if the store sells beer and wine.

The lottery license is a meaningful revenue stream — lottery commissions in Texas run 5% of ticket sales, and a high-volume station can generate $30,000–$50,000 annually in lottery commissions alone. TABC permits for beer and wine sales can add $100,000–$200,000 in annual inside revenue with margins comparable to other beverages. Both licenses require application and approval, and the transfer process takes 30–90 days depending on the license type and local jurisdiction.

Verify that all permits and licenses are current, transferable, and in good standing before closing. A lapsed permit can shut down a revenue stream. A denied transfer can eliminate a product category that the c-store depends on for margin.

## Valuation and Deal Structure

Gas station valuations vary widely based on fuel volume, c-store performance, environmental status, and real estate inclusion. A general framework for the Austin market looks like this.

A station pumping 100,000+ gallons per month with a strong c-store and clean environmental history trades at 3–5x SDE for the business, plus appraised value for the real estate. A station with lower volume, no c-store, and environmental concerns may trade at 1.5–2.5x SDE. The environmental status alone can swing the valuation by $200,000–$500,000.

Deal structure typically involves an SBA 7(a) loan for the business component, an SBA 504 loan for the real estate, seller financing for 10–15% of the purchase price, and buyer equity of 10–15%. Working capital requirements are higher than most businesses because fuel inventory turns weekly and c-store inventory needs restocking. Budget $50,000–$100,000 in working capital above the purchase price.

(Understanding the difference between SBA 7(a) and 504 financing is essential for structuring a gas station deal correctly. See [SBA 7(a) vs. SBA 504: Which Loan Is Right for Your Austin Business Acquisition?](https://travisbusinessadvisors.com/articles/sba-7a-vs-504-business-acquisition-austin) .)

## The Due Diligence Priorities

Gas station due diligence has a specific hierarchy. Environmental first — any contamination issue can kill the deal or crater the value. Fuel supply agreement second — confirm transferability and terms. Financial analysis third — verify fuel margins, c-store margins, and SDE separately. Licenses and permits fourth — confirm everything transfers. Real estate fifth — appraisal, lease terms, or title review.

The best gas station acquisitions in Austin combine strong fuel volume on a high-traffic corridor, a well-merchandised c-store with food service capability, clean environmental records with modern double-wall USTs, assumable fuel agreements with reasonable terms, and either owned real estate or a long-term favorable lease. Finding that combination takes patience. Moving on it quickly — with pre-approved financing and a qualified environmental attorney — is what separates buyers who close deals from buyers who watch them slip away.

Gas stations with underground storage tanks almost always require an environmental assessment during due diligence.
