Cash out refi - how to secure refi?

[Naz Hossain]

So I’ve been listening to the podcasts for a while and one pattern I’ve noticed is that, Brandon keeps saying, secure your refi before you go into a deal.

Taking on that advice, I've spoken to a few lenders. I have a current mortgage, primary residence, that I'm paying. When I asked lenders about doing a refi, they say "we look at your DTI". My question is, how do I work that refi when I'm already paying one mortgage? Do I get a tenant before I do that refi? How do y'all (those who have used the BRRRR technique) manage to keep your DTI low so that you can qualify for that refi?
