A piece of advise if he lays hands on you or your son immediately go to court and see if it qualifies for a peace order or similar. 

I have a son 2 years younger than your son… How did you go about moving your son along towards financial independence?  

My son is 22 years old and leading his 2nd large rehab (1st was about $40k, 2nd will likely be $50k).  

Will itemize for brevity purposes:- Mother wants to move to Saint George, Utah and get a home in a 55+ community- Me (son) has cash and wants to buy the home for her.

No it's your friends boomer parents giving the downpayment to your Gen Z/millennial friend to buy that house to their newlywed son with their new daughter in law/wife being emotional and running up the price because it's a "dream" house.

As a former college baseball player (albeit D3) and current coach for my 15U son, I commend you on your interest in real estate while still in school and playing ball.What type of property are you looking to acquire first?

By year end I will tackle a MF, value add with my son that would be sweet if we can swing the coop/tic (handling the finance challenges is the hurdle) so he ends up with a unit at below 50% of retail.  

I had a case where it looked like the umbrella policy could get used but 1) ended up Not being needed 2) was vehicle related, not RE related.Our Son’s girlfriend was driving one of our vehicles and got into an accident.  

My son began the process of Multifamilies a few years back based on teaching of @Michael Blank.

My sons are of homebuying age but the barriers to entry are so much higher than they ever were before.
