How do I leave a w2 job and remain bankable?

[Andrew Tucker]

I'm a BRRRR investor looking to leave a W2 in the relative near future. My goal is to fill my time pursuing my investing career and working as a 1099 contractor.
     I have been finding that conventional banking proves difficult until I’m able to prove two years of income on tax returns. 
 What are some good strategies in the meantime as I prepare to make the jump to be bankable in the early stages of my transition. As a BRRRR investor the refinance portion is crucial to keep pushing forward.
     I am willing to set up up entities and have cash that I can trickle into them but need suggestions on good methods of creating the right paper trail. 

Thanks
