You may have an adjustable rate mortgage (ARM) you're not entirely satisfied with. Maybe the mortgage rate is higher than you like, or the potential for mortgage rate increases looms ahead. If you plan on staying in your home at least five years, now might be an excellent time to switch to the payment security of a fixed rate mortgage loan. Or, if you plan on moving in less than three years, consider a home refinance loan and switch to a new ARM to take advantage of the low starting rates that may be available. Even if the new ARM's rate rises at the first adjustment interval, the starting rate may be low enough to offset any increased payment costs.
