Please poke holes in my thinking. From what I see, the 5 year arm is about 80bps below the 30 year. Rates I'm guessing continue to climb into next year where they'll peak and hover around 5 before the fed loosens things up. At which point with either the ARM or 30, you can refinance. You'd only get hurt if we never see rates below 5% again.
I'm looking at about $600K loan and 80bps is about 400/month in savings. In 5 years that's about $24K in savings and refinancing would be about $10K so you have potential save about $14K vs the 30 fixed. You'd only be screwed if rates never come down.
