There's a common misconception that adjustable rate mortgages are only for borrowers that can't afford a fixed rate mortgage. In fact, an adjustable rate mortgage, or ARM, can play an important role in the real estate market, especially to the savvy homeowner.
In this article, we're going to first explain what consumers can expect to find in the adjustable rate mortgage marketplace. We're also going to explain some of the pros and cons of this type of loan. Then we'll finish up by providing some online tools that allow users to compare ARMs to more traditional mortgage offerings.
An adjustable rate mortgage has a variable rate of interest applied to the loan's monthly payments. The interest rate is adjusted on a predetermine basis, and is usually varied with an index of inflation. The benefit of an ARM to borrowers is that lenders are able to offer lower rates of interest on the loans they write. They can do so because they've shifted the risk of rising interest rates to the borrower.
As just mentioned, the adjustable part of the loan applies to the interest rate charged the borrower. The rate of interest charged usually moves in step with a well-known indicator of inflation. The terms and conditions of the loan will state the exact index used, the most common of which include:
When the prime lending rate is used, the index is usually based on prime plus a margin basis. This means the interest rate charged will carry a premium (be higher) when compared to the actual prime interest rate.
In most instances, the terms of an adjustable rate mortgage will also include two "caps" or maximum allowable adjustments to the interest rate of the loan. The most common caps apply to:
This concept of these moving interest rates is best explained using an illustration.
In this example, the ARM's terms and conditions are for a $100,000 mortgage, with an initial interest rate of 5.50%, a 12.00% lifetime cap, and a 1.00% cap on adjustments.
What this means is the interest rate on the loan can never exceed 12.00%. In addition, the rate of interest charged after the first adjustment cannot exceed 6.50%, or 5.50% + 1.00%.
Adjustable rate mortgages will also indicate the allowable frequency of change to interest rates. Here again, the terms of the ARM will usually specify two variables with respect to this change:
Again, the best way to explain this concept is by using an example.
At this point, we're going to expand on the previous example. But this time we're going to explain further that this mortgage started in the year 2016 and it was a 5 Year ARM with a 12-month subsequent adjustment period.
In this example, the first adjustment to interest rates cannot occur before the year 2021; the resetting date. However, every twelve months after 2021, the lender is allowed to make additional adjustments.
When adjustable rate loans are quoted in the newspaper, or online, they're stated in a way that provides information on the frequency of change as well as the interest rates. For example, a 3/1 ARM indicates three years until the first adjustment, and one year for each subsequent adjustment. A 5/1 ARM allows the borrower to repay the loan for five years until the adjustments begin.
In today's mortgage marketplace, there are two additional variations that are worth mentioning: the hybrid and the option ARM. As a new homeowner it's important to understand the terms and conditions of an option ARM because this type of loan can actually result in what's called a negative amortization. Simply put, the loan can grow over time, not decrease.
A true adjustable rate mortgage is a loan where the interest rate adjusts on a consistent and predetermined basis. For example, a one-year ARM adjusts each year. Hybrid ARMs are quite common and the example used earlier is actually a Hybrid. The term refers to the fact the loan is at a fixed rate of interest for a period of time, and then floats later on.
For example, a 5/1 ARM is a hybrid that carries a fixed rate of interest for the first five years, then a floating rate of interest afterwards.
An option ARM is a loan that allows the borrower to choose how they would like to make a payment each month. Option ARMs can include three or more "options" or choices:
Option ARMs are often marketed with an extremely low rate of interest to lure consumers to the loan. The minimum payment feature found on this type of mortgage results in negative amortization. This means the outstanding loan amount, or principal, is increasing over time rather than decreasing.
While on the surface it might seem that adjustable rate mortgages are better suited for first time home buyers that cannot afford to make the monthly mortgage payments on a fixed rate mortgage, that's simply not true. They really do serve a valuable role in the marketplace.
Perhaps the biggest benefit of an ARM is the low rate of interest these loans typically carry. This rate is really just a reflection of the risk of rising interest rates being shifted from the bank, mortgage company, or lender, to the borrower. Since the borrower now bears the risk of rising interest rates, the loan can be initially written at a lower rate.
Another big benefit of ARMs applies to those homeowners that do not anticipate living in a home for a long period of time. It is not unusual for employees to be assigned to certain geographies for five years or less. In addition, the first time home buyer may purchase a "starter" house knowing they are not going to live there for more than three to five years.
In both of these examples, the homeowner is planning to sell the home before the adjustment period / resetting date begins. In this situation, they reap the benefit of lower interest rates, and the risk of an adjustment is minimized, or eliminated.
The biggest down side of ARMs is that they can give the homeowner a false sense of security about their family's financial health. Individuals might buy homes and stretch themselves financially by taking out a loan they can barely afford in the hope they will be able to find additional income before the ARM starts adjusting. This is, in fact, a very real danger that exists with this type of mortgage.
When thinking about choosing an ARM, do it for the right reason. Don't be fooled into thinking a new job will appear and the household's income is going to rise dramatically. Work with the lender, and they'll outline the maximum monthly mortgage payment possible with each loan type being evaluated.
