Trouble with cash out refinance on FHA duplex in Texas.

[Christian Montalvo]

Hi everyone! I was hoping someone could help me understand this issue I have run into... or send me a link where I could read more about it. My husband and I bought a duplex with an FHA loan in Dallas for $206K March 2016. One side has been our primary residence since then (we rent the other side out). I find myself bored on maternity leave in May of 2017 and decide to call Wells Fargo Home Mortgage to ask about a cash out refinance because I hear that the duplex next door to me appraised for $265K. The WF home mortgage Rep gets me all excited saying that it looks like we can refi and pull out around $10K cash! So we fill out the application but then he calls and says that the underwriter won't let us do a cash out because the duplex isn't listed as an investment property? I thought I remember not being able to label it as an investment property when we were applying for our FHA since it needed to be our primary residence for at least 1 year. So apparently we can only do the refinance... he said that he didn't know this either and told me to google it, but I'm having a hard time finding this exact verbiage. Can anyone explain this to me or point me in the right direction for some decent reading material on this particular subject? Thanks! Christian
