If a child is the executor of the estate and responsible for selling their childhood memories or parents work into the house may affect their sense of the value if they feel a high level of attachment to the house. 

Dude, I sold everything and went back to school full time at age 32 when I was married with one child and one on the way, and it was the best decision I ever made!

One of the selling features on the tenant side was that it was next to the school because that's where their child goes.

So with what I have read, having your in-laws invest in your LLC would not be allowed, since you are married to their child. 

I am married with one child.

My plan is to look for someone with decent credit, no evictions, no backlog of liens/child support, no felonies, minimum of 3x verifiable income, and employment for at least the last 2 years. 

@KevinWhat happens if there is no lease.Parents own the home, sell it without notifying the child (don't want to evict child).

Any interest they receive, of course, will be taxed at their ordinary income rate and it will take away any child tax credits and stuff they would normally qualify for, if the interest they receive is more than $600/yr each.   

Having my first child only 3 weeks ago I can't imagine 4!

My wife had our first child in January of this year and we JUST resolved a bill that the hospital tried to bill us for twice.
