Lower Mortgage Rates Helped Boost Home Affordability in September


Falling mortgage rates helped boost home affordability in September, Black Knight’s Mortgage Monitor shows.

In November 2018, when rates were nearing 5%, the share of national median income required to make the principal and interest (P&I) payments on the purchase of an average-priced home was 23.7%.

In other words, the average wage earner in the U.S. had to devote 23.7% of his/her paycheck to afford an average priced home.

Fast-forward to the end of September 2019 – with the average 30-year interest rate at around 3.64% – and it now requires 20.7% of the national median income to make monthly P&I payments on an average-priced home.

That marks the second lowest national payment-to-income ratio in 20 months, behind only August, according to Black Knight.

“To help quantify the boost this has given to homebuyers, consider that today’s prevailing 30-year rate has cut the monthly P&I payment to purchase the average-priced home by 10 percent [since November 2018],” says Ben Graboske, president of the data and analytics division for Black Knight, in the report. “Put another way, the decline in rates … has been enough to boost buying power by $46,000 while keeping monthly P&I payments the same.”

As the report points out, interest rate movements are a key determining factor of housing affordability – and significant shifts in either direction can change the landscape quickly.

What’s more, shifts in home prices can also have a significant impact.

“Despite falling interest rates and steadily improving affordability over the preceding eight months, annual home price growth held flat in August at 3.8% after rising for the first time in 17 months in July,” Graboske says. “It remains to be seen if this is merely a lull in what could be a reheating housing market, or a sign that low interest rates and stronger affordability may not be enough to muster another meaningful rise in home price growth across the U.S.”

When you say “Falling mortgage rates helped boost home affordability”, I have to disagree. When a house payment costs 50% or more of net income for 30 years, that’s not affordable.
