As rates are inching up but still very affordable, buyers should remember that there is an alternative to a fixed rate mortgage that can provide the lowest cost of housing for the homeowners who understand the parameters.

A $300,000 fixed-rate mortgage at 4% has a principal and interest payment of $1,432.25 per month for the entire 30 year term. A 5/1 adjustable mortgage at 3% has a $167.43 lower payment for the first five years and then, can adjust, up or down, based on a predetermined index.

Another interesting fact is that the unpaid balance on the ARM at the end of the first five years is $4,624 lower than the fixed-rate mortgage. The total savings in the first five years on the ARM is $14,669.00.

Adjustable rate mortgages are not the right choice for everyone but buyers should at least consider the options based on their individual situation. It could be an obvious choice for a buyer who is only going to be in the home for five years or less.
