Without significant apprection that could allow some extraction of value, the negative cash flow on some of these purchases at some point will go through most newbies reserves forcing a sale,   They are adults and made adult decisions and took adult risks.  

I also need a separate application filled out for each adult. 

My primary goal (whether it's a sound path or not) is to help my adult children build wealth along with us.

They made an adult decision and should be held accountable.

Quote from @Joe Jor: Looks like the DOJ has take up this case.Cite: https://www.justice.gov/usao-cdca/pr/former-ceo-orange-count...Joe Wow, when the Trump Justice Dept brings an Action against you for Grifting/Ponzi Scam, that's like the Bill Clinton Justice Dept. bringing a sexual harassment claim :)

We say that 4 adults aren't allowed.

While your kids are too young to be employees, you could still set up investment or custodial accounts (like a UTMA or UGMA) and fund them with some of your after-tax rental income, which can grow tax-free until they’re adults.

Not something sexually transmitted.

Sometimes an adult would come and coach a little, just for fun.

You rent to responsible adults with good jobs.
