Home with Side-Business Attached

[Eric K.]

I went and looked at an interesting property yesterday, its a SFR with an established home-business. It's on a few acres of land and generates up too 50,000 with little over head. (At least that's what they claim)

Has anyone had experience buying a property/business like this. Are there any additional legal head aches? Or other red flags? 

Thanks for any input,

Eric.
