Tenent is now concerned about safety issues and has a newborn in the house and it is los 30 degrees.

Some things I believe do not get discharged in a chapter 7 like federal taxes and child support etc.If your tenant gets their chapter 13 approved then still is likely a chance of rent default down the road as it's just too much pressure for them to balance the budget and stick with it.

The only thing that's keeping the Chicago Area population at bay are the newborns. 

I've dealt with glass, bones, shrimp tails, a child's toy, utensils, etc.

From what I’ve read, I am required to remediate this if a child under 6, is living in the house - however, this is not the case . anyone please advise how to proceed.

You probably won’t get any seniors renting from you but with my SFRs I often find that I get a couple or a family with just one child for my 3BR houses.

In Texas, a person's wages cannot be garnished by creditors unless it's for child support, alimony, taxes, or student loans.

Drugs, divorce, tenant share splits & the sudden appearance of a destructive dog/child are a common theme.
