Newbie purchasing question

[Diana Fernandez]

Good morning,

we came across a off market deal. It’s a duplex and each unit is 3 bedroom and 2 bath unit for 90k.  This is our first investment, we own in Cali so we’re stoked. This is we’re I would like your opinion... we were considering paying cash with part of it coming out of a cash refi since rates are so great=2.5% 15 year term. Would you pay cash???or consider qualifying for a small loan and just putting 20% down for tax right off? I want to take advantage of having equity in my cali home and the historical low interest rates to get a cash out refi. I don’t know if I’m the next year this will be readily available. I also understand the benefits of having tax right offs. Please help...
