Monopoly is the one I'd think of, but even sitting down with them and making your own game where they learn basic finances and budgeting (and how to do math) will put them ahead of most people. 

You deposit all your income into your loan/checking account and use expenses as needed and any remaining cash flow, sits in the loan thereby reducing interest cost and helps pay down mortgage faster.

We have been marketing to expired listings and contacting listing agents who's listings have been sitting on the market for months with price reduction after price reduction. 

I think there is less compliance issues, with a house the city is always sending you bs letters that you have to comply with. or a pipe bursting or someone falling in the parking. the hoa takes care of all these and takes these risks for you.I get the asteroid thing, just because there are drunk drivers out there you can't sit at home and be afraid to drive, I get all that, but these nasty lawyers will gladly gladly gladly destroy your life over the silliest thing. 

It's not just sitting back and collecting rent checks.

Also, I can imagine 7 x 1200 sqft homes sitting on one lot that is less than 1/2 acre.

Are you creating a partnership, is it a loan, etc   If you don't have an agreement you should sit down and discuss it and put it in writing. 

A 30-year fixed rate mortgage is currently sits around 6.6% interest:All else being equal, lower mortgage rates reduce the cost of ownership and, thereby, allow more people to afford to buy.

@Bill Brandt is definitely sitting pretty!

if something is just sitting on the MLS looking too good to be true... then it's too good to be true.these properties are going to have higher costs overall, be in more challenging neighborhoods, have very gnarly deferred maintenance and capex, potentially have liens, be high turnover, and require expert, highly knowledgeable, localized support to be successful. see for example this thread.https://www.biggerpockets.com/forums/48/topics/1137397-balti...and even at those price points, i think cash flow is fairly low to non-existent if rehabbed to a high grade, especially with DSCR debt.
