Your question involves a legal issue, so you should seek legal advice. 

I find when looking for a market to use the elimination method.

The first I'll tell you involves the family homestead in Peterborough NH, a big 1791 colonial farmhouse up on the hill that's been in the family for almost the entire time, though nobody has actually lived there full time in a few decades.

If the tenant violates the lease in other ways by how the treat the property issue them a notice to correct and if they don't correct the issue you COULD try to evict, BUT I would make sure the issue is VERY VERY clear cut because I have trouble believing a magistrate will allow an eviction for petty things or something that isn't 110% clear to everyone involved. 

Was a licensed engineer involved to design to repairs?

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

This is more of a tax planning matter, so it would involve working through several specific questions to tailor it to your situation.

Anything beyond that is going to have destructive consequences for everyone involved.
