Cash Out Refinance without W2?

[Sammie Baker]

Got our first investment property through a bank statement loan since we are self employed. We are putting 20% down and are stuck with a 6% interest rate. 

Two part question:

A:  I'd like to do a cash out refinance eventually but can I do this without a W2? 

B:  Is it possible to both lower our current interest rate (6%) plus get cash out of the property to use as a down payment for another investment property?

Ultimate Goal is to BRRRR all investment properties. (rent using STR-airbnb)

I appreciate any advice!
