Your other thing is what you say here, this idea of the BRR method is set all over that, but what you really need to do is don't refinance, because if you refinance now you're stuck in a house a year from now where the market collapses, your equities are gone and you can't pay the debt off. that one of the things is she talked about cash out, refinance.

I am debating on going full investor mode and start BRRR method on properties or flipping them.
