That's probably a good thing for society, and it's what the City wants (and needs).  

The main issue with models like those are that they are only good for 12-18 months before they have to get re-done with new data due to the fact that we live in a complex adaptive society and all the participants can make different decisions based on what changes in their environment. 

I liked this quote from @mitch messer"But here's my REAL question: When did we as a nation deputize landlords to be the last line of defense for addressing all the ills of poverty in our society?

I wish I had this shift in mindset about personal finance a few years ago so I wouldn't have to deal with this but it is what it is.

Between your book and Brandon Turner's "rent" book and "no money down" book...total paradigm shift for me when it comes to RE investing.

Sadly many people going to these events do not have a financial education and can easily be taken advantage of.Do we really believe as a society that someone is going to come out of pocket tons of money to instruct people they have never met on how to become a millionaire??

Despite higher borrowing costs and a shift in the market, there is limited supply of good quality income properties.

If you do 1 on 1 you have the opportunity to try to "Close" them on the rental.You also get a (kind of) "Feel" for them--friendly, scary, rude, loud, quiet, and small talk to learn about hobbies (ie. running a power buzz saw into all hours of the night vs collecting rare old stamps). with answers like, "When I get off shift at the Power Company at 11pm every night, I like to unwind by ripping huge pieces of wood into lots of smaller pieces for about 3 or 4 hours--is this a 230V 3-phase plug--because that's what my Industrial Table Saw needs?"

Play appreciation, but be careful of what markets you play; The homeless population doesn’t care what it cost to live in a market, but at a certain point the rest of society cannot afford it, nor can businesses justify it.
