How to "Refinance" in the BRRR strategy in less than 6 months!!!

[Kathy Lowery]

My lender states I need to show rental income on my taxes before I can refinance my investment property. Since I purchased it in December it won't  show until next year. 

How do I get around this? I hear investors say they refinanced in 3 to 6 months using the BRRR strategy all the time. Surely they can't be waiting until they file their taxes to do so.

What mortgage product will allow me to quickly refinance? There are no limitations (pre-payment penalty) on my existing mortgage. So I'm not sure why I have to wait so long. Does the quick refinance only apply if you purchased your investment property in cash? I've heard investors state they have refinanced hard-money loans in a short period of time. Does this not apply to a good old-fashioned investment property mortgage?

Thanks in advance!!!
