You will soon have a foreclosure on your record. 

He screens tenants in a very clever efficient manner. 

You going to manage yourself 10%, screen the tenants (between 1/2 and 1 month of rent for placement) fix the plumbing (hot water heater goes out $800), toilet clogs $150.

If I develop a sales funnel that works incredibly well at pre-screening and qualifying only sales listing leads, would it make sense to focus on generating these leads (locally first but then maybe regionally) and passing them on to other agents to follow through and close, simply sharing the commission, agreeably, in exchange?

It was listed 13 days ago, I have had 8-inquiries, 2-showings and 1 of which submitted an application and was screened yesterday.

Make sure your PM is screening to get the best of the best!

I guess you can take this as a "what not to do as a landlord" in the future - mainly, make sure you screen your tenants so you know you're getting someone you trust and like and also to not have month-to-month leases.

From there I eventually switched to just searching the county records for legal issues.  

Foreclosures are public record and used by everyone in town trying to nail the deal if the property has equity. 

We just use the assessor office for tax records.
