In this post, we look at the various attributes of families holding adjustable-rate mortgages (ARMs) and fixed-rate mortgages in the 2019 Survey of Consumer Finances (SCF). Despite the recent release of the 2022 SCF, we have actually chosen to utilize the 2019 SCF since it does not consist of any of the changes and characteristics related to the COVID-19 pandemic, which are beyond the scope of this article. Motivated by the present high mortgage rates, which can make exceptional ARMs more pricey when their rates reset, we have an interest in discovering which debtors are exposed to these higher rates. We found that households holding ARMs were more youthful and made greater incomes which their preliminary mortgage sizes were bigger and had larger exceptional balances compared with those holding fixed-rate mortgages.

Characteristics of ARMs

About 40% of U.S. households have mortgages, of which 92% have fixed rates and the remaining 8% have adjustable rates. Fixed-rate mortgages have a set rates of interest for the life of the loan, which need to be paid on top of the primary loan amount. Adjustable-rate mortgages have rates that normally track a benchmark rate that shows present economic conditions and is more carefully impacted by the rate of interest set by the Federal Reserve.Although rates for ARMs are developed to be adjustable, rates on ARMs are frequently fixed for an initial period, normally five or 7 years, after which the rate is usually reset annually or twice a year. Additionally, ARMs may have limitations on just how much the rates can change and a total cap on the rate.

For example, throughout the Fed's existing tightening duration, the 30-year mortgage rate increased from 4.8% in October 2018 to 7.6% in October 2023, while the rate on the 5/1 ARMThis implies the rate is totally free to change each year after being repaired for the first five years. rose from 4.1% to 7.6% throughout the exact same period. To put this in viewpoint, think about a family that obtained $200,000 utilizing a 5/1 ARM in October 2018. This home made regular monthly payments of $964 during the first 5 years of the mortgage. The regular monthly payments then increased to $1,412 in October 2023, when the rate changed.

By contrast, a fixed-rate mortgage would not experience an increase in payments in 2023, having secured the lower rate for the life of the loan. Given this threat, fixed-rate mortgages normally have higher introductory rates. Had the family gotten the exact same $200,000 in a fixed-rate mortgage at 4.8%, the payment would have been $1,053 in October 2018, however then it would have remained constant in 2023.

Mortgage payments account for about 30% of home earnings, and as we displayed in an earlier Economic Synopses essay, impressive mortgages represent about 70% of home liabilities, so this increase in month-to-month payments represents a considerable additional burden on homes.

Identifying Households with ARMs

To understand which families are most impacted by modifications in rates of interest through ARMs, we determined the share of households with mortgages that hold either ARMs or fixed-rate mortgages across the earnings circulation and compared some general qualities of these households and their mortgages, including the rates, the preliminary size of the mortgages, and the staying balance.

The figure listed below programs the share of mortgages by earnings decile. Overall, ARMs a minority of total mortgages.

Distribution of Types of Mortgages by Income Decile

SOURCES: 2019 Survey of Consumer Finance and authors' calculations.

NOTE: Households are divided into income deciles, in which the first decile represents those with the most affordable income and the 10th represents those with the highest income.

As displayed in the figure, the share of mortgages that have adjustable rates is usually higher among households in the higher-income deciles: 18.8% in the leading decile (the 10th) compared to 6.5% in the bottom decile (the first). While our numbers are based upon the 2019 SCF, this Wall Street Journal article reported that ARM applications were simply over 7% of all mortgage applications in 2023

One possible explanation for why holding ARMs is more concentrated in higher-income deciles is that families with greater earnings are more able to soak up the risk of higher payments when rate of interest increase. In exchange, these homes can benefit right away from the lower introductory rates that ARMs tend to have. On the other hand, households with lower income may not have the ability to afford their mortgage if rates adapt to a considerably higher level and hence choose the predictability of fixed-rate mortgages, particularly because they have the alternative to re-finance at a lower rate if rates drop.

The table listed below reveals some other general qualities of ARMs and their borrowers versus those of fixed-rate mortgages and their customers.

ARMs tend to have lower rates of interest. However, the mean preliminary loaning quantity is over $40,000 larger for ARMs, and the median remaining balance that families still need to pay is likewise bigger. The mean home earnings amongst ARM holders is likewise 50% more than the mean earnings of those holding fixed-rate mortgages. This is constant with the figure above, in which the share of ARMs increases amongst higher-income homes. The mean age of ARM holders is also 18 years lower.

ARMs Appear to Skew toward Younger, Higher-Income Households

In sum, ARMs appear to be more popular with younger, higher income homes with larger mortgages, and ARM ownership relative to fixed-rate ownership almost tripled from the bottom to leading earnings decile. Given their age and income, these types of families might be much better geared up to weather the risk of fluctuating rates while their proportionally larger mortgages benefit from the lower initial rates.

1. Although rates for ARMs are designed to be adjustable, rates on ARMs are often repaired for an introductory duration, usually five or 7 years, after which the rate is usually reset every year or two times a year. Additionally, ARMs may have limitations on how much the rates can alter and a general cap on the rate.
