Why pay off a low rate interest.

This would also allow me to keep my primary at a low rate loan. 

----------------------------------------------------------------------------------------------------If I had to start all over again, I'd look to acquire a 2-4 unit property with an FHA low-down payment mortgage.

They are inexpensive, they usually come with mineral rights (big plus in Texas), they typically have short redemption periods, low rehab costs, and sell quickly at the right price; they also have large ROI. 

The net result is basically the same, but it keeps the two properties separate from a lenders perspective.Any low down payment money, particularly on an investment property, is going to come from a private money lender.  

Look for properties with low taxes, separate utilities, strong demand, and potential for rent increases.

Yes, there are many different ways to get it back, so the risk is low.

However, if your current interest rate is low, be aware you will be buying into a deal with much higher interest rate with today's rate.For your new purchase, you should be able to use a DSCR loan and get financing without income as long as credit is good.

Quote from @Bonnie Low: The "best market" is less about the market per se and more about the deal you're able to find in my opinion.
