Joseph, the best method for you would probably be the MLS or sites like realtor.com etc.

best of luck. i would network in that area and go to as many meetups you can and learn the area well

If it would concentrate on rent collection only and do it well, it might be okay.

They don't communicate well, don't take responsibility for their actions, do not clean or maintain homes well, and will shaft you when it's time to leave.Other than that, it's a pretty good system.

And I copied that idea for the core of my portfolio (although I also invest in alot of passive deals as well, in the satellite portion for a core-satellite approach).

Most everything I would nonrenew a tenant for would likely be known to me without trying to "screen" existing tenants before renewal.

Well, those will need attention after every moveout.This is where your tenant screening comes in. 

This works well I would say 98% of the time. 

Without rent control i either raise their rent far above market rents so they give me notice (my preferred method) or i simply do not renew their lease.
