When rates of interest are low (as they have actually been throughout the real estate crunch), you can re-finance your loan to secure the lower rate. For more on refinancing, see listed below. The very first advantage of ARMs are that your monthly payments, a minimum of for a time, will likely be lower than fixed rate mortgages.For instance, during this extended housing crunch, rate of interest have actually gone gradually lower and are currently at historically low levels. Those with ARMs have benefitted by paying less in interest each month (although since of interest caps, it's most likely that ARM holders have not been able to take complete benefit). Some lenders will provide lower, marked down introductory rates of interest for ARMs than for fixed rate loans.
