I also meet alot of people in my line(s) of work and this seems to check out in my conversations with them, this includes natives, recent transplants, old transplants, every age group and race.

In Illinois, the minimum age to officially become an unlicensed assistant is 18.

Are there any investors between the ages of 18 and 25 in this group?

Further, we need to account for a $10k “reserve” for what will be repairs / maintenance as the property ages.  

I definitely think with your age and the money you have, I would look into a vacation type area that has STRs.

These days, a couple of things seem to be affecting how and where college age students are attending classes.

Old age?

At his age, it’s not like he can start investing or manage a property, so I’m trying to figure out how to nurture this interest without overwhelming him. 

And I'm gettingso nervous and stressed out, I don't know how much longer I can bear all this.I also discovered that her mother had moved in with her and her two teen-aged kids. 

Then divide that cost by the amount of time between now and then and that's how much you should be putting aside for Capex.For general maintenance, the age and condition of the building will play into that.
