It is a 30M fund on the verge of failure.

A mechanics lein stops my sale if they actually do the work.

Both units were filled at the time of purchase, but both had to be evicted a few months later due to failure to pay rent.

Check for cracks in the foundation, condition of the mechanicals, any water coming into the basement, etc. 

And, know this:  The #1 reason that Landlords fail is their failure to manage to the lease (source: American Apartment Owner's Assn).  

Regardless if it was for tall grass, unlicensed vehicles, leaving the trash out too long, malicious animals, failure to keep snow removed from path to mailbox etc. 

We have a clause in our lease that plumbing clogs not caused by mechanical/material defects in the plumbing will be charged to the tenant, and if your lease doesn't have similar I would recommend such a clause.

A third reason people are selling is failure to run their business and their finances on a fiscal year.

My perspective was from a small business private lender rather than RE lending, but the mechanics were largely the same. 

AS we see some GP failures there is another thread on this guy Lane Kawauka not sure how you spell it but one of his investors gets on BP and says they go dark..
