I know this is what screening a tenant is for, but still can be a bit sketchy.

The screening process plays a big role in the odds of collection.

There are more serious red flags that come up during the screening process. 

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

Haha, no I wasn't that slack in my screening. 

I know I'll have to do major screening but seems to be very successful/passive as someone who at one time had 200 section 8 SFR rentals.. there is a lot of miss information about the program..

It's always best to do your own research, just like screening for a good renter.Start by going to www.narpm.org to search their directory of managers.

I completed this a few months back but never got anything to prove it (other than the screen print showing filing successful) so I've been a bit worried by it.  

I am worried about having an intermediary taking control of my property and renting to tenants I haven't screened.

Fair enough, I have partial ownership of a commercial (apartment) building in the Bay Area and I would estimate it as a Class A- to maybe Class B - great location, great tenants, nice amenities (not high end like gym, new pool, community room with big screen TVs, etc), high rents, but building is older (built in 1950s).One investor I saw post that they look at where Starbucks and Costcos are opening and possibly factor that into looking at different markets.
