Cash Out Refi or down payment and mortgage?

[Jordan Butts]

So a little background, I have tested the waters and flipped a couple of houses with a private investor, but as many of us want, I am ready to be on my own.  My question is, should I focus my current cash flow into paying off my current mortgage and getting a cash out refinance to fund a rental or possibly more flips, or should i save up a 25% down payment and get a a mortgage on the rental while still paying my home mortgage?  My home mortgage is at about $90,000 with 2.875% fixed 15yr and I am only in year 1 still and its appraisal is $150,000.  Living frugally, I could have it paid off by the end of 2018, although I would like a rental sooner.
