They split before he acquired property but they have an adult son. 

We moved to southern California when the market crashed, as our adult kids were here.

I've been in real estate related businesses all of my adult career.

I've yet to meet a demon 1 year old but a lot of nasty entitled adults.

And yet it's been given to you.Did you read "Robinson Crusoe" when you were a child or young adult?

As a young adult or student we are forced to live like one by living on a budget(barring a ton of help from mommy and daddy or irresponsible student loan borrowing).

At that point, kids should be starting college (or whatever adult path they choose to take).

Where I live there are a few siblings or parents/adult children that have joint practices.If you are able to keep your debt below $300-400K ($43-57K per year for schooling), it will help you in the long term. 

It's borderline criminal what the government does to push college and student loans onto young adults when they get out of high school.

Our (adult) children know all about our holdings, real estate and otherwise, how much we've invested & how much we've made, but most of the other family members don't even know we own rentals.We discuss renters, rent prices, house prices, strategies, etc. with others in the business, but no one else is really interested, except maybe those who want to ask about things that are none of their business.
