sure sounds like a tenant from hell. but here are a few things to think about. number 1, they are not your tenants any more, so the court will not look favorable upon them. 2nd, read my profile, i am a home inspector here in new york, with mold remediation as a specialty. there are 18 different types of black mold, and ONLY 2 OF THEM ARE TOXIC. so, your chances of having the toxic variety is slim. 3rd, you have to have either very large quanities of black mold and have it be the toxic kind to make it harmful to people, i. e., airborn. 4th, if these tenants are sick from black mold, then why did you have to go thru court to get them out??

It is most likely that the prospective tenant has already been denied several times by applying through a real estate agent, or property management company; and they know that their chances of being accepted through this process is slim.  2.

My experience has been, once they owe more than a months rent, the odds of you ever seeing that money are slim. 

Like @Vince Mathis said about Phoenix, Rapid City has slim buy options and tight margins...lot's of forced appreciation.

There's Cleveland which is a cash flow king but your appreciation is slim and its a long term game. 

Cost me $100 service call on a rental unit that runs a very very slim margin of profit to begin with. 

The odds of that happening are slim to none though, but anything can happen and no one has the ability to see what may be coming?

Good contractors are slim pickins up here right now, but I know a couple pretty decent contractors looking for interior work for the next few months.

The likelihood of him really taking you to court is Slim.

With the appreciation we've had in Denver the past two years (supported by significantly fewer foreclosures) I think that the pickings are very slim for your approach (Sub2).
