Question to all the Brrrr Enthusiasts!

[Jacob Hodge]

New to this community and REI as a whole. I've been very intrigued with the BRRRR method, however after some late night reading through the forums I have a couple questions. So for anyone who is experienced with the BRRRR method:

1: Why is this method so difficult and unreliable now? 

2: What methods of investing are you using instead of the BRRRR method?

Thanks for taking the time to answer some of my questions! Any answer is knowledge in my eyes, which is what I’m looking for before starting to dip my toes in the market.
