December 2019 Mortgage Monitor
Low Interest Rates Make Housing Most Affordable in Two Years Despite Accelerating Price Growth; Buying Power Up 16% since Late 2018

- Home prices continue to react to falling interest rates, with December marking four consecutive months of acceleration in the annual rate of growth and the largest single-month acceleration in more than 6.5 years
- After falling from nearly 7% in early 2018 to 3.8% in August 2019, the national home price growth rate gained nearly a full percentage point increase over the last four months of 2019, climbing to 4.7% to close out the year
- Still, 30-year interest rates falling to 3.6% in late January 2020 made housing the most affordable it’s been since early 2018
- Despite the average home price increasing by nearly $13,000 from just over a year ago, the monthly mortgage payment required to buy that same home has actually dropped by 10% over that same span due to falling interest rates
- It now requires 20.6% of median monthly income to purchase the same home as it did just over a year ago, the smallest such payment-to-income ratio in two years
- Put another way, buying power for those shopping for the average-priced home has increased by 16% (approximately $48,000) in just over a year’s time
JACKSONVILLE, Fla. – Feb. 3, 2020 – Today, the Data & Analytics division of Black Knight, Inc. (NYSE:BKI) released its latest Mortgage Monitor Report, based upon the company’s industry-leading mortgage performance, housing and public records datasets. Drawing upon the latest data from the Black Knight Home Price Index (HPI), this month’s report examined home price growth and affordability in the context of today’s lower-interest-rate environment. As Black Knight Data & Analytics President Ben Graboske explained, low interest rates throughout much of the back half of 2019 contributed to sharply accelerating home price growth – but also to improving affordability.
“After falling from nearly 7% year-over-year appreciation in early 2018 to a trough of 3.8% in August 2019, the national home-price-growth rate gained a good deal of steam as mortgage interest rates declined throughout the second half of last year,” said Graboske. “In fact, December marked four consecutive months of home price growth acceleration and the largest single-month acceleration in more than 6.5 years, while the annual rate of appreciation saw nearly a full percentage point increase over the last four months of 2019, closing out the year at 4.7%. The low end of the market, those homes in the bottom 20% by price, saw 6.6% annual growth, nearly three times the rate of the top 20%. That said, higher-priced homes have been more reactive to recent rate declines. The annual growth rate among the top price tier has more than tripled over the past four months – from 0.7% year-over-year in August to 2.3% as of the end of the year – while there’s been very little acceleration at the lowest end of the market.
“Still, even with home price growth accelerating, today’s low-interest-rate environment has made home affordability the best it’s been since early 2018. At that time, the housing market was red-hot, with national home price growth at 6.6% and climbing – before rising rates and tightening affordability triggered a pullback in growth rates. That’s not the case today. Despite the average home price increasing by nearly $13,000 from just over a year ago, the monthly mortgage payment required to buy that same home has actually dropped by 10% over that same span due to falling interest rates.
It now requires 20.6% of median monthly income to purchase the same home as it did just over a year ago, the smallest payment-to-income ratio we’ve seen in two years. Put another way, prospective homebuyers can now purchase a home that is $48,000 more expensive than a year ago, while still paying the same in principal and interest. That’s a 16% increase in buying power. Recent history at comparable levels of affordability suggest acceleration in home price growth may well continue in the coming months as this increased buying power puts upward pressure on home prices across the country.”
In light of interest rates falling to 3.6% on Jan. 23 according to Freddie Mac’s weekly Mortgage Market Survey, this month’s Mortgage Monitor took an updated look at the population of potential refinance candidates in the market. There are now 9.4 million 30-year-mortgage holders in good standing who have at least 20% equity in their homes, credit scores of 720 or higher and who could cut their current interest rate by at least 0.75% by refinancing. This is the largest the population has been since mid-October 2019, when interest rates briefly fell below 3.6%. On average, these borrowers could save $264 per month, for an aggregate monthly savings of nearly $2.5 billion. While down slightly from the $2.6 billion aggregate potential savings in August and September of 2019, it is three times the volume of savings available at the beginning of last year.
