The duplication is mentioned by name by Santarelli and on the slide also included the following entities: Linens and Things, Stein Mart, Modell’s Sporting Goods, and RadioShack (37:52).

People mentioning that they put their life savings in something in hopes of a better future is gambling.

I'm ok with gambling on it.

Kind of like sports star's endorsing a care or something.

Stop hanging out with your deadbeat buddies who spend all day drinking, talking sports, and otherwise wasting away.

Abandon the Peurto Rico dream for now and look at more realistic/beginner friendly areas that still sport a large latin influence and strong rentals, like Florida (I've looked a little bit outside Miami..Boca Raton, Tampa, West Palm Beach, etc). 

I'm not saying you can't make a decent return on rentals - I and many others here have done great with it - but if you have a well-functioning, profitable business that you know, why would you gamble money into Memphis *******es, to put it bluntly? 

My wife and I run collegiately and can potentially get schooling and living expenses (such as housing) paid for with a sports scholarship.

Making money is a team sport. 

Rooming houses usually don't get to take advantage of sporting events, concerts, festivals that usually result in spikes in rental fees and more profits ( and glory) that AirBnb and other STRs get to.
