Now for the back house, I had to get the tenant out and do necessary maintenance and repairs, which turned into a mild/mini rehab.

I am not sure if you are looking for specific feedback... so here goes... your approach seems a bit mild to date.As soon as I have the first indication that a tenant is deviating from the lease I start the process of keeping them off balance until they are retrained or leave.By keeping them off balance I mean the actions you mentioned, the action MikeOH mentioned, things like doing formal Safe and Clean inspections with followups... and the first day their check bounces... into court they go.While Mike recommends getting physically in their face...

He went on to explain that all the remediation company will do is wipe it down with Dawn dish detergent and repaint the surface.I would love to save on the rehab costs but do not want to set myself up for issues down the road.
