The auto email will automatically send you listings as they come on the market.

Is that to say that once their lease is up, they just are automatically granted squatter's rights by our government?

I'm not going to say that it's necessarily an automatic no-go, but you should be aware that financing there is more difficult and you may have more legal disclosures/work to make sure you're doing it right.

There is a lot of shifting right now, so that money may have dried up in the current environment.Also be aware that in many areas there just aren't many foreclosures. 

And people will automatically believe the allegations.

Dropping in $50-100k to make it a duplex won't automatically mean it's worth that much more.

So you adjust, you shift, you listen to those that have made the mistakes, and hopefully, you avoid them.

A multi-member LLC is automatically taxed as a partnership. 

A consult your advisors clause in an offer letter might help you avoid legal repercussions but the decision to move forward with a deal or not should face a more stringent test than, "Will I get sued and/or prosecuted".I don't think you should automatically proceed because someone appears to have their wits about them.

The game has changed overnight and the laws that were supposed to be equitable for all parties have drastically shifted to disadvantage property owners.
