I would refi, but I think you could get a lower rate. We just closed our refi last week. We bought for $330,000 in Nov. 2011 and had a 30 year fixed FHA @ 4.125%. We just refinanced online through Quicken Loans. Really painless process, by the way. We got an FHA Streamline @ 3.375%. We had to bring $2,300 to closing (they timed closing to be when our old mortgage would have been due anyways, of course), and the refi added about $3000 to our current mortgage. We are very happy!
