Recycling your money.

@Ana Patrice I think @Jorge Ruiz nailed a great strategy for scaling a rental portfolio with the ability to recycle your money multiple times over. 

What determines whether or not you to continually recycle all of your money has more to do with how much value your able to generate with each deal... example: if you're able to acquire at a below market price then in crease it's value by 25%, then there are products which should allow you to recycle your money indefinitely.
