Nobody sells a running business if it is doing good. Find out the actual reason why they are selling. Dont just believe the reason they say what it is. With the cash flow / profit, looks like a good store. (by the way with experience of dhoti ko ma ghanta haneko,) in black and mexican neighborhood, you get REALLY good business, they spent everything, they dont save in bank like white folks. Then again there is give and take, crime is high.
I hope it helped a bit.
