Should You Get An ARM?


Before the Great Recession, there were all kinds of financing options available.  Some good, some bad, and some downright ugly.  The people left to pick up the pieces after the recession blamed the ugly financing options for the financial meltdown.  After the recession the lending standard pendulum swung to the right and many of the pre-recession “creative” financing options went away.  The adjustable rate mortgage (ARM) was one of the creative options that went away.  A little more than 10 years and a greatly improved economy later, and that pendulum is swinging back to the left.  We’re starting to see the ARMs making a comeback.


With all the jargon and options out there, it’s no wonder first-time home buyers’ heads spin. Even seasoned veterans have a hard time keeping up with all the different ways to get into four walls and a roof. The Adjustable Rate Mortgage (ARM) is gaining interest again because the initial interest rates and closing costs are typically lower than fixed-rate loans. If considering an ARM, it is really important to understand the pros and cons to ARMS and the different options available within this category of home loan.


What is the major difference between a fixed rate loan and an adjustable rate loan? It’s where the risk falls. The lender assumes the greater risk with a fixed rate mortgage because no matter how high interest rates go, the borrower’s interest is locked in for 30 years. That’s why fixed interest rate loans have higher interest rates. ARMs, however, put the risk squarely on the borrower.


Those low up-front rates help not only with monthly cash flow, they also have another value: most of the time, borrowers can get more financing with ARMs. ARM qualifying rates are less than fixed-rate loans, so lenders also offer ARM borrowers more liberal qualification ratios. For instance, with a fixed-rate loan a lender might allow 28 percent of a borrower’s gross monthly income for the payment of principal, interest, taxes and insurance. But with an ARM the qualifying ratio is usually higher, say 33 percent. Put these two factors together – lower initial qualifying interest rates and more liberal qualifying ratios – and you can borrow quite a bit more than you would with a fixed rate loan.


So how do ARMS work? The ARM interest rate is determined by an “index” that fluctuates with economic conditions and a “margin.” The margin is a set figure that is added to the index. Lenders use several different types of indexes, including measures based on the movement of treasury bills, the 11th District Cost of Funds, and the LIBOR rate (more about this one in a minute). Most ARMS have adjustment periods every six months or annually. And the good news is that most ARMS have consumer protection rate caps that keep mortgage rates from swinging wildly from year to year. A typical rate cap on an annual basis is 2 percent, or 2 percent above or below the previous year’s rate.  If you are offered an ARM without a rate cap, do not walk away….RUN!


There are various kinds of ARMS – 3/1, 5/1, even 7/1. This means that the interest rate can’t go up or down – is locked in – for a period of three, five or seven years. There are plenty of ARMS, however, that only stay locked in on one rate for the first six months. These are all considerations when shopping for a loan. In addition to getting a lower interest rate, ARMs typically have lower closing costs – big settlement expenses would neutralize the benefit of the low rate.


An interesting ARM option is called the LIBOR (London Interbank Offering Rate) ARM. It’s a complicated product, but one that is worth researching for certain types of borrowers. The London Interbank Offering Rate is the rate that international banks based in Europe charge each other for overnight funds. Now here’s the kicker – LIBOR ARMs often have a much lower interest rate than others. The interest rate on an ARM has a lifetime cap of 13 percent, and monthly payments can’t rise more than 7.5 percent annually. And like any other rate, it fluctuates, but it’s worth looking into.


There are also options in how the loan can be repaid. It can be repaid in the same way a fixed rate mortgage is – with a fully amortized monthly payment that pays off the loan in 30 years. ARM borrowers can make minimum payments, which produce “negative” amortization, i.e., some of the interest due on the loan goes unpaid. The unpaid interest is then added to the loan amount, increasing the debt. You can even make an “interest only” payment. Of course, this means the borrower is not paying down the loan balance, but the upside is a very low minimum monthly payment. Also, there is a one-year prepayment penalty on the loan. This means the program is not good for anyone who plans on selling his or her home in 12 months.


The LIBOR ARM might be the financing you’ve been looking for if:

  • You’re looking to minimize your monthly payment.
  • You’re seeking to lower your interest rate and monthly cash flow.
  • You want to take advantage of the equity in your house. This is a good refinance program for those who want to consolidate consumer debt such as credit cards.

Any ARM is a good idea if:

  • ARM interest levels are significantly below fixed-rate interest charges
  • You won’t be staying in the house for more than five years (especially if you have a locked-in rate for the first three, five or seven years)
  • You anticipate a higher income in the future (such as a young professional just starting out)

ARMs are not a good idea if

  • initial rates are comparable to fixed-rate loan rates
  • high closing costs offset the low interest rate
  • the rate environment is volatile
  • rates are at historic lows and expected to increase


Before the great recession, many borrowers with long term plans were told they could take advantage of the ARM for 3/5/7 years and then refinance out if the rates started getting higher.  The problem was that many people were not able to refinance out for a variety of reasons.  When rates started going up, monthly payments went up, and borrowers could no longer make their payments.  As a cautionary note, DO NOT assume you can refinance out of an ARM into a traditional fixed mortgage at any time.  In general ARMS are not the ideal financing product for the vast majority of borrowers.  There are some specific circumstances and borrowers that are a great match for an ARM.  Be sure to discuss your situation and future plans with a trusted lender when considering an ARM.
