How do you know if Tenant is growing weed or doing meth lab?

[Jack Ni]

Hello, my name is Jack. For those with a lot of experience in hand, how would you know if your tenant is growing weed or doing meth lab in your rental properties? If you deal with this before, how did you figure out they are growing weed or meth lab? What are the chance of me renting to someone that will grow weed or meth lab in my proeprties? Both of my properties are in B class neighborhood and are currently renting to families with kids. Also the city I live in have VERY LOW crime rate. I’m not suspicious of my current tenant growing weed or anything like that (very nice people), I just want to learn how to avoid those type of tanant. Also, I heared that if a tenant is doing meth lab in your property, the bank can foreclose or call the loan due? (I still have a mortgage); I don’t think the bank can foreclose if tenant was just growing weed. Not really sure, just want to check if it’s true.

Thank you.

Hahaha.... such random things to be worried about.  Be cautious if the prospective tenant tells you his name is Heisenberg.
