I got an email. It said "cashflow for life!!!" 

but the only thing I could see was...

There is no way a rental apartment building can supply cashflow for life. It can only supply Cashflow for the life of the dollar bill. And since all paper currencies devalue to zero, that may not be very long.

The fiat currency graveyard has claimed EVERY non-gold-backed currency in mankind's history. Real goods and real money constitute real freedom not the US dollar.
