Arms actually can be a pretty good deal depends on the rate difference, between a arm and a fixed rate alternative. I got a 5-1 arm at 4.25% when 30-year was 5.75. Mine has a limit on how much they can raise the rate also, it is around 2% the first adjustment and 4% over the life. Over thirty years worse case I pay $198,780 for a 5-1arm based on 4.25% fixed for 5-years with a loan amount of $100,000, than rising to 6.25% for 5-years and rising to 8.25% for the last 20-years, that is worse case, rates may drop or I might move. The 30-year fixed will cost me at 5.75% on $100,000, $210,086 over the same period. The proof is in the numbers. Also it is a personal choice, can I accept the risk and possible get the reward, also is it likely I am going to move at some point? Same with points it is all in the munbers and risk.
