Renting to Resturant workers

[Sam D.]

Hello, I was wondering what is your experience OR opinion about renting to a restaurant owner?

I am told in my rental property 4-6 people will live and the owner of the restaurant is willing to may more than the market price.  
Few of my concerns - What if there is someone illegally living in my property? What if they sue me? What if the owner instead of putting 4-6 people decides to put 10 people? 

May be I am over thinking this. I will ask the restaurant owner and people who will be living to sign the lease. (some safety...)

What do yo think of the overall situation.

Thanks

Sam
