When the market crashed my husband, our adult kids and their kids all left Redding, CA and moved to Orange County, CA.

I just answered a similar question in another BP thread, see this:http://www.biggerpockets.com/forums/52/topics/1855...Next time, when you enter into a residential rental agreement, list all adults who reside in the unit as jointly and severally liable.

You should already have complete copies of the existing Rental Agreements, so next steps will include terminating existing agreements when and how local law allows (at end of current term which must be honored unless there is mutual agreement to change); have Rental Applications completed by all adults that are occupying the premises and obtain current verification of all facts, background, credit, etc. before offering to allow them to stay by signing a new Agreement with your terms and conditions.

I tried to calm him down and asked about his adult children who live nearby, maybe he could stay with them.

This made it nearly impossible or very complicated for adult children or other care takers to unwind an unscrupulous transaction that took advantage of seniors with cognitive declines.  

The fact is you don’t really know what is going on there in the neighborhood day to day and this is a disagreement between 2 adults.
