First American Real House Price Index

Real house prices changed

-38.4%

since the pre-recession peak

The First American Real House Price Index (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 and across the United States at the national, state and metropolitan area level. Because the RHPI adjusts for house-buying power, it is also a measure of housing affordability.

"Existing homeowners' refusal to list over concerns about finding a home to buy is a critical driver of supply constraint," says Chief Economist Mark Fleming.

What makes it a Real House Price Index?

House prices are typically reported nominally. In other words, without adjusting for any inflation. Just like other goods and services, the price of a house today is not directly comparable to the price of that same house 30 years ago because of the long-run influence of inflation in the economy. The RHPI helps provide an alternative view of the change over time of house prices in different markets across the country.

Why does the RHPI tell a different story than other house price measures?

Changing incomes and interest rates either increase or decrease consumer house-buying power or affordability. When incomes rise and/or mortgage rates fall, consumer house-buying power increases. Traditional measures of house price affordability are dependent on the assumption of specific loan terms (down payment, LTV, DTI) and the choice of income level (i.e. median or average household income). The RHPI is not dependent on any of these assumptions and so it more broadly reflects the real price experienced by consumers regardless of their income level or the loan terms specific to their situation.

3 Key Drivers

The three key drivers of the First American Real House Price Index (RHPI) are incomes, mortgage rates and an unadjusted house price index. Incomes and mortgage rates are used to inflate or deflate unadjusted house prices in order to better reflect consumers' purchasing power and capture the true cost of housing.

What do the RHPI number values mean?

The RHPI is set to equal 100 in January 2000. So, a state with an RHPI value of 110 in 2016 has seen real house prices increase 10 percent since 2000.

What does the RHPI reveal at a market level?

Let's consider San Francisco and Detroit and look at the RHPI for each.

Since the peak of the housing crisis in 2006, many metropolitan areas have experienced large drops in unadjusted house price levels followed by, in some cases, impressive gains. However, when measuring metropolitan house price appreciation using our consumer house-buying power adjusted Real House Price Indices, the story looks very different. For example, San Francisco and Detroit both experienced similar real price declines, about 60 percent over the course of three years, and very little "recovery" has occurred in real prices. The common perception is that San Francisco, the shining example of the new economy, and Detroit, the tarnished example of the old economy, couldn't be more different cities when it comes to housing costs. Yet, after adjusting for income growth and mortgage rates and their influence on house-buying power, real house prices in both cities remain well below the pre-recession peak. So, really how different are these two markets?

July 2017 Real House Price Index

Supply Squeeze Tightens Grip on Affordability in July

The First American Real House Price Index (RHPI) showed that in July 2017:

  • Real house prices increased 0.6 percent between June and July.
  • Real house prices increased by 10.4 percent year-over-year.
  • Consumer house-buying power, how much one can buy based on changes in income and interest rates, decreased 0.4 percent between June and July, and fell 4.2 percent year-over-year.
  • Real house prices are 38.4 percent below their housing-boom peak in July 2006 and 17.2 percent below the level of prices in January 2000.
  • Unadjusted house prices increased by 5.8 percent in June on a year-over-year basis and are 3.4 percent above the housing boom peak in 2007.

The RHPI is available below as an interactive tool that can be used to look up and compare real house prices at the state and metropolitan area levels, and also offers additional perspective on income and interest rate changes.

Affordability Sags in July Due to Rising Rates and Increasing Nominal Prices

  • According to the National Association of Realtors, the number of existing homes listed for sale declined to a 4.2-month supply, which marked the 27th consecutive month of falling inventory levels. The lack of supply is driving unadjusted house prices higher.
  • According to our latest Real Estate Sentiment Index (RESI), one critical reason for the supply constraint is that existing homeowners are unwilling to list their homes for sale for fear of not being able to find something to buy.
  • Higher interest rates, which increased slightly to 3.97 percent, combined with rising unadjusted house prices, reduced affordability by 0.6 percent in July compared to June.
  • Last week, the FOMC announced that it will begin to reduce its large portfolio of bonds, which is likely to push mortgage rates higher in the coming months. This quantitative un-easing will further impact affordability.
Chart: Supply Squeeze Drives Rapid Price Growth

"Rising rates and rapid price appreciation driven by the lack of supply caused affordability to decline in July. Based on our RHPI, affordability has declined by more than 10 percent over the last year. But, the loss in affordability is only significant to potential first-time buyers. Existing homeowners with fixed-rate mortgages benefited from the rising prices with increased equity. You’re perspective on rising home prices and affordability largely depends on whether you are a homeowner or not," said Mark Fleming, chief economist at First American.

"As mortgage rates rise and supply remains constrained, affordability will continue to decline for those seeking to achieve the goal of homeownership. Yet, while affordability is lower than a year ago, it remains high by historic standards. Only three states and the District of Columbia are less affordable today than they were in January 2000," said Fleming.

About the First American
Real House Price Index

The traditional perspective on house prices is fixated on the actual prices and the changes in those prices, which overlooks what really matters to potential buyers - their purchasing power, or how much they can afford to buy. First American's proprietary Real House Price Index (RHPI) adjusts prices for purchasing power by considering how income levels and interest rates influence the amount one can borrow.

The RHPI uses a weighted repeat-sales house price index that measures the price movements of single-family residential properties by time and across geographies, adjusted for the influence of income and interest rate changes on consumer house-buying power. The index is set to equal 100 in January 2000. Changing incomes and interest rates either increase or decrease consumer house-buying power. When incomes rise and mortgage rates fall, consumer house-buying power increases, acting as a deflator of increases in the unadjusted house price level. For example, if the unadjusted house price index increases by three percent, but the combination of rising incomes and falling mortgage rates increase consumer buying power over the same time period by two percent, then the Real House Price index only increases by 1 percent. The Real House Price Index reflects changes in house prices, but also accounts for changes in consumer house-buying power.
