Looking for laws and best practices around it but I am seeing conflicting things.

(Also, I got to practice removing asbestos in the containment suits and breathers and that is *NOT* a fun job.)

There is a multitude of reasons, some of which are above, that naming all adults on the lease have become a standard practice, and most board of realtors leases have this in their standard leases. 

I was saved my the bell, the property was listed incorrectly and the broker was a bit shaky with their practices.

If you choose to self manage, for starters, follow the HUD screening best practices and that will help tremendously. 

NO OTHER BUSINESS practices should be conducted by either party except for that property only. 

In theory (if not practice), if the foreclosure already occurred, any liens behind the foreclosing entity were wiped out.

From a practical standpoint, get some reps under your belt with even a 2-6 unit multifamily on your own. 

So I do practice what I preach, and it works pretty well. 

Putting a lien on the house is probably not practical if you are part owner.
