Advice on a refi needed. To do or not to.

[Eric Bermudez]

So I was looking to refi my home and Im on the fence about it. My ultimate goal is to get into real estate and purchase multis. I owe $147, 000/15 yrs left on my home and have a FHA loan with a 4.0%. I went to broker to see what I can do. With my credit score being 630, i could get into a conventional loan but at 4.8%/30yr in which i could also pay off a few loans which would help increase score and possibility use FHA in future for purchase. My current mortgage would increase by around $65 monthly but having paid off loans would give me extra $700 in my pocket monthly. Do I think long term and do it or should I look at other options. Any advice is appreciated.
