Adjustable-Rate Mortgages
Flexibility now, and in the future
An adjustable-rate mortgage (ARM) loan from RBFCU has a fixed interest rate for the first five years. After that, the rate can change every five years for the remaining life of the loan. When the rate of your ARM changes, your monthly payments will increase if the rate goes up and decrease if the rate falls.

Which loan type is better: a fixed-rate mortgage loan or an adjustable-rate mortgage (ARM) loan?
The choice depends on your financial goals. A fixed-rate mortgage offers the security of an interest rate that does not fluctuate during the life of your loan. So when interest rates are low, many prefer a fixed-rate mortgage. When interest rates are high, an ARM can offer the benefit of receiving a lower rate, which may help you qualify for a larger loan.
-
Does RBFCU offer other options besides a 5/5 adjustable-rate mortgage (ARM) loan?
No, not at this time.
-
On a 5/5 adjustable-rate mortgage (ARM) loan, how frequently can my interest rate and payment increase?
An adjustable-rate mortgage (ARM) loan is designed to lock in both your interest rate and payment for a designated term. After the initial term has lapsed, your interest rate and payment change. For example, in a 3/1 ARM loan, your interest rate and payment are locked in for the first three years of your loan, then both will adjust every year following your initial term. On an RBFCU 5/5 ARM loan, your interest rate and payment are locked in for the first five years of your term, then adjust every five years after that.
-
I’ve heard that adjustable-rate mortgage (ARM) loans are risky. Is that true?
ARM loans offer the opportunity to get into the house of your dreams sooner than you think. At the same time, it is best to understand how an ARM loan works and to ensure it meets your overall financial plans. Call our Mortgage Resource Center at 210-945-3300 and speak with a Mortgage Lending Representative.
