A neighbor in NJ rented a house across the street and they had small children who put their mouths on the sills which had lead paint and caused developmental delays in the child.

So is having a child and needing a bigger place. 

Because of my age, I may not legally sign a purchase and sales agreement (required to wholesale), I am about to go to college which I am completely undecided in and about to completely switch markets.

This year I have signed leases with 2 different tenants who have a small child.

One million is child’s play!

My question is should we start an S corp with child LLC's for each property or start out with an LLC? 

Not sure if the same will apply to an adult child.

My Mom just passed away (I’m an only child and she had a brutal death; I was her primary caregiver with little kids in tow), this is my childhood home, and this tenant is clearly a con artist.  

If they're your parents, or a child, that's one thing, but owning rental property to supplement someone else housing costs is not a good investment strategy.

That is my opinion.If you add more homes to your portfolio, I would look at setting up a series LLC with each unit in it's own child LLC.
