What I know is allowed is having as many as five unrelated adults living in the same household.

My initial plan is to get new leases for the tenants, background checks on all adults, get security deposits, and verify who is living in the units.    

It is often the case that one of the spouses or adult children do not have great credit score with a good explanation. 

It's all about respect and being considerate of others, but I don't know how to communicate that to adults who clearly aren't seeming to understand.

Susan allowed her adult son, Roy, to stay with her sporadically (4 months in Pasadena, 8 months elsewhere).

According to the most recent count, one out of four homeless adults in the region are 55 or older, and the need is expected to increase.

They stated there would be 4 persons living in the unit and we have 4 names on the lease, however - how they've added two more adults - an ailing father and a child from maybe another parent they have custody over4.

You'd still be required to legally sign a promissory note and offer up a mortgage or deed of trust.What one might consider is finding a trusted and willing adult to be the "front-person" when it comes to signing legal documents.

So now we happen to be a bit more mature, and being real adults. 

@Matt Todd wow that was a mouth full, I had no idea about the 3 tenant max that's very interesting I'll have to keep that in mind, I would already be worried about younger adults leaving every summer if it was Orem or provo college tenants.
