Unless he's paying cash, the bank will want to see the repayment ability of the business. Debt service coverage is the primary repayment source, followed by collateral and guarantor support.Financials only tell you how well the LAST person managed things.
Traffic count is much more important - as well as knowing what type of customer you’re going to potentially attract.
A small shop with no competition nearby next to a state park / campground for example that draws tourist for example is a gold mine. You have people who depend on you - have cash ready to spend and who will pay gas station prices on snacks/drinks as well as a premium for fuel. Compare that to an independent station on the interstate where you likely will face corporate competition who will underprice you until your gone.
Know your markets and find a niche - key is make sure no one else can muscle in once you get established - I/E liquor license and making sure no one else can get one near you. The moment you start showing a real profit - too many people will jump in split the market until it’s profitable for no one.
Why would he want to buy a business without knowing what revenue the business generates? Margins are thin and inventory can be stale. Gas stations and C-stores are risky ventures. Traffic count and all the other amenities that come with the business are important but they should be reflected in the financials, otherwise you may be buying a pig in a poke.
One more thing, this type of business is heavy in cash. Not surprisingly, a lot of the revenue goes unreported. Either way, this is a huge decision and you owe it to yourself to investigate every possible pitfall. Like Reagan once said, "trust but verify" Good luck
