Refi two properties to purchase more-what to consider?

[Ian K.]

I've got two properties that I would like to refi and use the equity to purchase more properties.  What do I need to consider?  

Is it best to refi one and then the other or do them both at the same time? 

When I refi, the properties I own will still be cash flow positive but my DTI will increase a lot until I can redeploy the equity to purchase more properties. I wonder how lenders treat this? What do I need to look for in a lender or what questions should I ask to speak about this process? I have a hunch there are terms for this that I don't know.

Thanks in advance!
