We've just been approved for a HARP re-fi through SunTrust, who holds the current mortgage. No appraisal, reduced fees, minimal paperwork.
We'll be going from 5.125% to 4.125%. I opted for a 25 yr term instead of 30, so the monthly amount won't go down quite as much as it would have if I'd stayed at 30 yr, but we'll still save about $200/month. Roughly $3K in closing costs will be rolled into the new 25-yr mortgage. So original purchase July 2007, then a re-fi in March 2009, now another re-fi three years later.
