Is Homeownership Bad for Wealth Accumulation?

Friday, November 24, 2017

By William R. Emmons

House prices have risen significantly from their low point after the Great Recession. Homeowners’ equity (HOE)—the market value of U.S. households’ residential real estate minus the value of home-secured debt—has increased even more in percentage terms; this is because leverage in the form of mortgage borrowing amplifies price gains, resulting in proportionately larger HOE wealth accumulation.

Leverage is a double-edged sword, however, as debt financing also magnifies house price declines, causing even steeper percentage losses in HOE. In fact, long-term data suggest that debt-financed homeownership, when compared with other sources of wealth such as stocks, bonds and savings accounts, may not generate returns high enough to compensate for the higher risk.1 Might concentrating a family’s wealth in homeownership that is financed with a large mortgage be hazardous to the family’s wealth? This seems especially likely for less wealthy families who may be vulnerable to income disruptions. 

Why Recent Gains in House Values Are Misleading

Total HOE increased by $6.9 trillion between 2011 and 2016, according to the Federal Reserve’s Financial Accounts of the United States.2 After adjusting for inflation, this gain was $6.4 trillion, representing an average annualized increase of 13.5 percent. 

Adjusted for changes in the number of households, inflation-adjusted HOE rose by 12.5 percent annually during 2011-16, compared with an average annualized increase of 4.4 percent for all other types of household wealth (Table 1, Column C). Both figures are far higher than their respective annual averages during the longest prior period available (1947-2011) of 0.5 percent for HOE and 1.2 percent for all other wealth.

Nonetheless, three important pieces of long-run evidence suggest caution in advocating homeownership as a primary means of wealth accumulation for many families. First, HOE increased less than nonhousing wealth during the longest period of available data, 1947-2016, albeit by a small margin. Table 1 shows that nonhousing wealth increased by 1.5 percent annually, while HOE increased by 1.4 percent even with the strong increases in homeowners’ equity in recent years.

Second, the volatility of HOE during this long period far outstripped the volatility of nonhousing wealth (Table 1, Column D). This has been especially true in recent decades, as reflected in the figure below. While the estimates in Table 1 include the volatility of HOE in excess of house price variability induced by leverage, they do not reflect the extra volatility experienced by a family holding an undiversified housing portfolio—namely, a single house. Some research suggests that individual house prices may be twice as volatile as broad house price indexes; this lack of diversification, combined with leverage, can increase a family’s risk significantly:

“The high volatility of individual house prices, together with high transaction costs, lead to low Sharpe ratios (defined as average excess return on an asset, divided by its volatility) on housing.”3

Thus, when properly measured, investment in an individual house may be riskier than investments in nonhousing assets, as leverage amplifies the effects of house price fluctuations on HOE and virtually all families own just one house.

Cumulative Increases in Average Housing and Nonhousing Wealth

Finally, another Federal Reserve dataset, the Survey of Consumer Finances (SCF), reveals that housing wealth is especially volatile for black and Hispanic families (Table 2, Column C). Despite very high volatility, the average increases in the value of these families’ HOE are no higher than the gains experienced by white families. In contrast to the aggregate data described above, the SCF shows that nonhousing wealth generally increased much more than housing wealth with no higher volatility. (See comparative results in Table 2 and Table 3.)4

Avoiding Homeownership for Building Wealth 

To be sure, owner-occupied housing provides benefits to many families. It may be difficult to find rental housing of the quality, location, style, etc., comparable to owned housing. Owning provides a hedge against the risk of future rent increases; however, owning also means forgoing potential declines in rental housing costs. Owning also can make moving more expensive due to associated buying and selling costs. 

There are portfolio diversification benefits to owning a house, as house price changes and returns on other assets are less than perfectly correlated. Overall, however, our data show that leveraged homeownership is riskier than nonhousing wealth and provides average increases that are no higher (and may be lower) than returns on nonhousing assets. This suggests that caution is warranted from a wealth-building perspective. 

Black and Hispanic families have long maintained higher concentrations of housing in their portfolios than have white families, as shown in Table 4.5 This is an important reason why blacks’ long-run wealth trajectories have been lower and more volatile than those of whites. High concentration in housing also has made Hispanic families’ wealth much more volatile, although their average returns have been similar to whites’. Homeownership can be part of a financially sound household’s portfolio, but evidence suggests that it should constitute a limited share of total assets.
