intentional damage caused by tenants, DEFENSE?

[Idan Narotzki]

HI dear all, 

I just close my first SFH rental deal in C+ neighborhood. While working to set insurance, I've noticed the insurance company DOES NOT cover intentional damage caused by tenants. They said that maybe some company can cover it for a very expensive fee (above 120$ per month).

- As a beginner in RE, I am wondering, how do you PROTECT yourself from such a scenario? 

I understand that a good screening process can make a huge difference. 

1. How involved can I be in the screening process? and what should I must verify in it? 

2. I've heard about "keys for cash" concept, which basically means reward the tenant with 500$-1000$ (I should get 900$ rent), if he didn't ruin the house, when the lease ends. What do you think about that? Does anyone do it? 

Thank you very very much for your help!!!
