Networking - I meet people in person and online, here for example, trying to build up my SOIMy Worst 3:1.

What can I do to protect myself, as I want to avoid inheriting a tenant who may not pay rent on time or may need to be evicted after closing?

well when you compare to what 90% of investors at least on this site do is buy rental houses or apartments..

Looking for advices on quitclaim deed.

Nice house, but it sits on a corner lot and lacks an ideal backyard.

For example, garage disposals, tenants don't think about what goes down there and how it breaks or mess with your sewer lines.  

do they post their personal phone numbers on A BNB ?

I look for recommendations on places like NextDoor, where local folks are complainers. 

You can do it on a manufactured home DSCR loan.

The time depends on lease length and how long they've been living there.I would also recommend reaching out to their caseworker (if they have one) to let them know the lease will not be renewed.Section 8 voucher holders are incentivized to vacate quickly in order to keep their voucher and avoid having to pay full-market rent out of pocket elsewhere.Hope this helps!
