Thoughts on 10/1 ARM?I'm looking at a 120 day lock on a 10/1 jumbo ARM at 3.75%, no fees but a $5,000 deposit refundable at closing, with a one-time float down within 60 days of closing. 30 year jumbo fixed is 4.25%, but .25% non-refundable fee for the 120 day lock with one free float down w/in 60 days. We are putting 20% down.We plan on staying in the home for 7-10 years. Perhaps longer, but in a perfect world we will be in a position to move to our dream house before we are there for 10 years. Hence going with a 10/1 (or possibly a 7/1). I figure worst case we are there for more than ten years, refi into another ARM (perhaps 3/1 or 5/1 if we still hope to move), but with a higher rate and lower principal balance. With any luck, our payment would not be much higher with the shorter ARM term and lower prinicipal balance.Any general thoughts/crystal ball prognostications that can help me decide on the 7/1, 10/1 or 30 year fixed?
