Reality Check - Is it worth performing Due Diligence?

“Am I paying the right price?”

That’s the first question you should ask before becoming interested in a gas station listing. The truth? Many deals on BizBuySell (and even broker listings) are wildly overpriced — especially when real estate is included.

The good news: you don’t need to be a CPA to figure this out. A simple gut‑check formula can save you months of wasted energy (and thousands in mistakes).


The Quick Reality Check

Here’s how to know if a station is even worth due diligence:

  1. Check Fuel Margins

    • Gallons sold × cents per gallon (profit, not retail price)

  2. Add Store Margins

    • Inside sales × 25–35% typical margin

  3. Subtract Payroll + Expenses

  4. Run SBA Loan Numbers

    • 10–20% down, 10% interest, 10‑year term (default assumption)

  5. See if You’re Positive

    • Net profit should be solidly positive and ideally yield 10–20% cash‑on‑cash


Why It Works

  • Fast filter: You’ll cut 90% of listings instantly.

  • Price sanity: Compares replacement cost (build new) vs. asking price (buy existing).

  • Margin of safety: You’ll know if upside (food program, EV, car wash) is needed to make it work.


Try the Spreadsheet

We built a free “Price Reality Check” calculator you can use right now:

How to use it:

  • Follow the workflow, enter data into the input fields and watch the calculated fields update

  • Plug in gallons, margins, payroll, and expenses

  • See instant cash‑on‑cash results

  • Request access if it’s view‑only (I’ll approve quickly)


Next Step

  • Run the numbers on 3–5 listings you’re eyeing

  • Drop the losers fast (negative cash‑on‑cash)

  • Focus due diligence only on the survivors

  • Move to Phase 2: Deep Underwriting when a deal pencils out


Stop guessing — start owning.
Every great acquisition starts with a reality check. Use the spreadsheet, run the math, and buy with confidence.
