ARM Versus Fixed-Rate Mortgages


In this blog, we will cover and compare ARM versus Fixed-Rate Mortgages when buying and refinancing a home. Most mortgage loan programs, whether it is FHA-insured mortgage loans or conventional mortgage loan programs offer adjustable rate mortgages and fixed-rate mortgages.  There are pros and cons of ARM versus fixed-rate mortgages.

Is it Better to Get an ARM or Fixed-Rate Mortgage?

There are advantages and disadvantages of these types of programs depending on the mortgage loan borrower and their needs.  Factors like how long a homeowner is intending on staying in the home are important in choosing an ARM versus fixed-rate mortgages. Also, how often the homeowner is intending in refinancing plays a vital factor in choosing ARM versus fixed-rate mortgages.

What Are Fixed-Rate Mortgages?

Fixed-rate mortgages are by far the most popular mortgage loan program most home buyers and refinance mortgage loan borrowers choose.

Fixed-rate mortgages are mortgage loans that have fixed rates for the term and life of the mortgage loan.

For example, a 30-year fixed rate mortgage loan with a starter mortgage rate of 4.25% has a 4.25% mortgage rate for the life of the 30-year mortgage loan.  Whether interests skyrocket or plummet, it does not affect the mortgage loan borrower.  They are secured with 4.25%.

Why ARM Is Better Than a 30-Year Fixed-Rate Mortgage

If the interest rates plummet to 2.75%, the homeowner can choose to refinance their current 4.25% mortgage rate loan to a new 2.75% mortgage rate mortgage loan.  There are several types of fixed-rate mortgages.  30-year fixed-rate mortgages, 25-year fixed-rate mortgages, 20-year fixed-rate mortgages, 15-year fixed-rate mortgages, and 10-year fixed-rate mortgages.

How Does a 30-Year Fixed-Rate Mortgage Work?

Will all fixed-rate mortgages, once the term of the mortgage loan is up, the mortgage loan has been paid in full.  Monthly payments on fixed rate mortgage loans, the monthly payments are inversely proportionate to the term of the mortgage loan.  The longer the term of the mortgage loan, the lower its monthly mortgage payment is.

Mortgage Payments on ARM Versus Fixed-Rate Mortgages

The shorter the term of the mortgage loan, the higher its monthly mortgage payment is because, with the shorter term mortgage loan, the homeowner is repaying the mortgage lender the balance of the loan over a shorter period of time.

Shorter-term fixed-rate mortgages normally have lower interest rates because the mortgage lender has a shorter-term liability on mortgage rates.

Also, with shorter-term mortgage loans, you will save thousands of dollars in interest because you are paying the balance of the mortgage loan in a shorter period of time.

ARM Versus Fixed-Rate Mortgages

Adjustable rate mortgages are also referred to as ARM. Adjustable rate mortgages, ARM, differ from fixed-rate mortgages where the interest rates can change over the term of the mortgage loan.  One great advantage of adjustable rate mortgages versus fixed-rate mortgages is that the interest rates of adjustable rate mortgages are substantially lower than fixed-rate mortgages.

Mortgage Rates on ARM Versus Fixed-Rate Mortgages

Factors Affecting Mortgage Rates

The reason why adjustable rate mortgage interest rates are much lower is that the mortgage lender is not obligated to guarantee a certain interest rate for the life of the mortgage loan.  Mortgage lenders only have to guarantee a certain interest rate for the fixed rate period and after the fixed rate period is over, then the new interest rates adjust based on the index rate.  This reduces the risk factor for the mortgage lender.

How Do Adjustable Rate Mortgages Work?

With adjustable rate mortgages, the mortgage interest rates are fixed for a certain period of time and after that period is over, the mortgage interest rates adjust every year for the term of the mortgage loan, and the new adjustment is based on the index, which changes depending on the type of index, plus the margin, which is constant for the term of the loan.  For example, say that you get a 5/1 ARM with a starter rate of 3.0%, and a margin of 3%. based on the COST MATURITY TREASURIES ( CMT, one-year treasuries ).

Why ARM Versus Fixed-Rate Mortgages Is Better?

With this adjustable rate mortgage loan program, your interest rate will be 3.0% for the first five years of your mortgage loan.  After the fifth year, your new mortgage interest rate will adjust.  If the CMT, index, is 2.0%, your new rate will be the index plus the margin, 2.0% index plus the 3.0% margin, or 5%.  Say on year number 7, the INDEX drops to 1.0%, then your new interest rate will be the 1.0% index plus the 3.0% margin or 4%.  Your interest rate will adjust every year until the term of the loan.

ARM Versus Fixed-Rate Mortgages: Which Should I Choose?

Depending on your long-term goals, adjustable rate mortgages may or may not be the best choice for you.  If you plan on purchasing a home and living there for the long term, then a fixed-rate mortgage may be the best option for you since you have security with the fixed-rate mortgage rate.
