Lack of financial documentation in DD

[Gulliver R.]

Would you buy a park that lacks proof of rental income coming into the bank (i.e. Lack and inconsistent bank statements, deposit slips, and tax statements)? Seller is ma and pop and didn't document every month (has some months of rental income documented but not much). He's the type that would just take the cash for rent once in a while. FYI there is no mortgage on the property. I mentioned seller financing and he is semi-open to it. Is this a deal breaker?
