Rising Rates Expected to Dull House-Buying Power, According to House Price Index

First American Financial Corporation

First American Financial Corporation, a leading global provider of title insurance, settlement services and risk solutions for real estate transactions, today released the August 2021 First American Real House Price Index (RHPI). The RHPI measures the price changes of single-family properties throughout the U.S. adjusted for the impact of income and interest rate changes on consumer house-buying power over time at national, state and metropolitan area levels. Because the RHPI adjusts for house-buying power, it also serves as a measure of housing affordability.

Chief Economist Analysis: Nominal House Price Appreciation Sets Record for Third Straight Month

“In August, year-over-year nominal house price appreciation reached 20.7 percent, the third consecutive month it has set a new record,” said Mark Fleming, chief economist at First American. “According to our Real House Price Index (RHPI), which measures housing affordability in the context of changes in consumer house-buying power, incorporating changes in household income, mortgage rates and nominal house prices, affordability declined 16.6 percent. The growth in nominal house prices vastly outpaced the 3.5 percent increase in house-buying power compared with a year ago, yet real, house-buying power-adjusted house prices remain 37.5 percent below their 2006 housing boom peak.”

Is This the End of Housing’s 40-Year Tailwind?

“The overall downward trend in the average 30-year, fixed mortgage rate has been one of the most important driving forces of both purchase and refinance activity for the last 40 years. Holding income constant, lower mortgage rates allow a borrower to borrow the same amount for less. As mortgage rates have drifted lower over the last several decades, borrowers have seen their purchasing power increase, which has facilitated move-up buying, higher housing market turnover (more sales as a percentage of the housing stock) and increased refinancing activity,” said Fleming. “Average mortgage rates won’t stay as low as they are today forever, and as they rise, the decades-long housing and mortgage market tailwind will turn into a headwind. Rising mortgage rates, all else equal, will diminish house-buying power, meaning it will cost more per month for a borrower to buy ‘their same home.’

“Multiple factors point to modestly higher mortgage rates in the months to come, including continued inflation, an ongoing economic recovery, and the possibility of the Fed beginning to taper its purchase of mortgage-backed securities,” said Fleming. “The popular 30-year, fixed mortgage rate is loosely benchmarked to the 10-year Treasury bond. When global investors sense increased uncertainty, there is a ‘flight to safety’ in U.S. Treasury bonds, which causes their price to go up, and their yield to go down. The opposite is true when the economy is improving, as it is now and as it is widely expected to continue in the months ahead. Consensus forecasts predict that mortgage rates will hit 3.2 percent by the end of the year, and 3.7 percent by the end of 2022. So, let’s examine how these mortgage rate scenarios would impact house-buying power.”

Rates Above 3.5 Percent Likely in 2022

“We can use the RHPI to model shifts in income and interest rates and see how they either increase or decrease consumer house-buying power or affordability. When incomes rise and/or mortgage rates fall, consumer house-buying power increases,” said Fleming. “If the average mortgage rate increased from its August level of 2.84 percent to the expected end-of-year level of 3.2 percent, assuming a 5 percent down payment, and the August 2021 average household income of $68,658, house-buying power falls by approximately $21,500. If rates increased to the anticipated end of 2022 level, 3.7, percent, house-buying power would fall by $49,000.”

Higher Income to the Rescue?

“Rising mortgage rates impact affordability, but one of the root causes of rising mortgage rates is an improving economy, and an improving economy often leads to higher wage growth. In fact, our estimate of average household income increased approximately 0.2 percent on a monthly basis in August 2021,” said Fleming. “If incomes continue to increase at a rate of 0.2 percent per month through the end of 2021, the higher income will reduce the projected end-of-year 2021 decrease in house-buying power from $22,000 to nearly $18,000. And if incomes continued to grow at 0.2 percent through the end of 2022, the projected end-of-year 2022 decrease in house-buying power would drop from $49,000 to $35,000.

“Rising household income limits the negative impact that higher rates will have on house-buying power. Rising rates will lower affordability, but rising household incomes can help to mitigate the impact. Ultimately, changes in affordability depend on the tug-of-war between rising household income and upward pressure on mortgage rates.”
