Quote from @Andrew Syrios: So basically note investing is really trashy and you're looking for a continuous stream of income but instead of alimony or child support it's loan payments instead? 

You’ll have to be very lucky or willing to buy a problem child property and/or neighborhood.  

My wife and I have a child as a member on each property(last man standing gets it all). 

I went through the same thing a while back where I ended up with over $100k in debt, overdue mortgage payments and child support to pay.

@Lauren Cutchen Bought a house where the sellers child had scratched his name into the stainless steel fridge door.

I have lived in (with a small child) and own multiple pre-1978 homes that most likely had lead paint in them.

The adult child would not likely be able to afford to purchase in the neighborhood where the parents live.

Just think, if that was YOUR child, living with vermin.

With all that said, I would like to have one house per child to help them with family formation when it becomes time, so I'll likely end up with a couple more. 

I was even able to travel to a country I always dreamed of traveling to since I was a child whilst maintaining my airbnb from across the world (Japan).
