They perform a vital function in our society recycleing properties in need. 

I had a dismantler come to my property, strip the home of any recyclable metal, then crunch the rest of it up with a back hoe and put it in a dumpster.

Therefore, different strategies tend to be better or worse suited for different markets at different points in the RE cycle.

Or do a cash out REFI and just recycle that money.

While the movement has a green / re-use / recycle / reduce aspect, I think that part is almost by default.  

An uncle who farmed got an extra cow to keep us in milk.  

Depending on your terms and how fast you're being paid back, you could recycle that same 100k multiple times a year each earning 8%.

Working for a large wholesaler, I see a lot of investors that do repeat business with us because we have consistent inventory and we don't milk every single deal we do and instead we focus on consistent more conservative fees so that our investors have plenty of room.

If a buyer is dumb enough to allow their agents to call shots on how much commission they are willing to show a property for, I’d rather just milk the buyer and let them pay their greedy agent instead of me!

You cannot recycle your cash as quickly as you can with Burrr investing, but frankly not everyone has the time to do that.
