Shotty or Illegal Addition

[Gina Dobbs]

Should I make an offer and see how thinks shake out on inspection?

I found a property that could be a potential flip in a semi rural area. When I walked around it today it looked like the building had a fairly shotty addition put on at some point. I worry that it may be an illegal addition, but a part of me thinks I should just make an offer and see what shows up on inspection. 

What do you lovely people think I should do?
