You just need to get the numbers and compare them. They'll give you a good estimate of what everything will be. I refinanced a 60k mortgage from 5.5 to 2.6, took out 15k for renovations and my payment is less than what it was before. I got a 5/5 arm from penfed because they paid all the closing costs but the interest rate may go up to as high as 4.6 in 2019 which on a 60k loan will be like 50 bucks a month. So, in my scenario if I'd had to pay closing costs it would have taken like 4 years to recoup it.
Refinancing is a lot easier than buying in my experience, don't be scared.
