The BRRRR method is dead

[Adrian Smude]

I believe the BRRR method is dead or at best on life support! The last decade has been easy for investors to use the BRRR method, but now we need to learn other methods. I've been learning these other methods for over a decade because I went through the last recession when banks stopped lending.
Why I believe the BRRR method isn't going to work in the next seasons of investing:

1. Bank rates have gone up which won't allow most properties to cashflow
2. Banks have tightened their lending requirements which aren't allowing most people to qualify.
3. Appreciation has slowed and even flattened in markets which means there isn't free money any more.  

What other reasons do you think the BRRR method is in the past?
