Adjustable Rate Mortgages (ARM ) ARM’s are mortgages whose rates adjust according to the terms of the contract you made with the lender.Usually interest rates are fixed for the first 1, 3, 5, 7 or 10 years. After that period is up, rates will be allowed to fluctuate within the limits of your contract with the lender.Terms are usually 15 or 30 years (although you can negotiate just about any duration you want). There can be a balloon involved.Because the lender is not taking as big a risk on losing money if interest rates rise, these loans will have a lower initial rate than a fixed mortgage. The lowest rates will be for 1 year ARM’s and will go up accordingly.Many people will take out an ARM even in period of low rates, such as now, because they get even lower rates and are able to afford more house. However, the borrower is taking the risk that he can still afford the house after the rates are free to rise.It used to be common for the contract to limit fluctuations to 2% a year. However, 5% swings are becoming more the norm. Depending on what happens to interest rates, you might find yourself priced out of your house. Of course, you could renegotiate if rates start to go back up.The average homeowner owns his or her house for approximately 7 years. If you plan to move before the initial fixed term of the ARM is up, it’s a good choice. If you plan to stay longer than ten years, a fixed rate might be a better option.
