What other strategies or philosophies are out there beside BRRRR?

Hi Bigger Pockets

I really enjoy reading the forum, blog, as well as BP books by Brandon Turner and Trench.  I enjoy trying to figure out what strategies will work best for me.

It does seem like many members here are all about BRRRR. My question is what other strategies are out there? What are other ways people grew the number of rentals they had? Not necessarily grew to 50-100 rentals, but how do people who dont embrace debt as easily get to 5-10 rentals?

I figured there was more than one way to skin a cat so curious about other success stories, strategies, books, etc on how people grew the number of rentals.
