This is just my personal opinion, but I would not even think of getting an ARM when rates are as low as they are right now.
You might think that you’re going to move in 7 years (not sure if that’s why you’re considering the ARM), or think that prices will be higher in 7 years so you can “refi” (into what??? — chances are rates will be higher if prices are higher), but you cannot predict the future.
What you DO know is that rates are very low right now. IMHO, you should take advantage of that.
