House Hacking - renting bedrooms, screening tenants

[David Yamamoto]

Hello folks,

For those that have house hacked while renting out bedrooms to tenants... how do you screen them?   This seems a so much more personal when you have to actually share the same living space with tenants.  Do you screen with a company or do it yourself? This is a brand new concept to me... 
(Property in question is a 3b single family home). 

Thanks,
David.
