Inflation Adjusted House Prices 2.3% Below Peak
House Price-to-Rent Ratio Declines to 3.1% Below Peak
It has been over 16 years since the bubble peak. In the Case-Shiller release Tuesday, the seasonally adjusted National Index (SA), was reported as being 64% above the bubble peak in 2006. However, in real terms, the National index (SA) is about 13% above the bubble peak (and historically there has been an upward slope to real house prices). The composite 20, in real terms, is about 4% above the bubble peak.
Both indexes have declined for three consecutive months in real terms (inflation adjusted).
People usually graph nominal house prices, but it is also important to look at prices in real terms. As an example, if a house price was $200,000 in January 2000, the price would be almost $338,000 today adjusted for inflation (69% increase). That is why the second graph below is important - this shows "real" prices.
Nominal House Prices
The first graph shows the monthly Case-Shiller National Index SA, and the monthly Case-Shiller Composite 20 SA (through August) in nominal terms as reported.
In nominal terms, the Case-Shiller National index (SA) and the Case-Shiller Composite 20 index (SA) are both just below all times highs set in June. Both indexes declined in August, with the National index off 1.3% from the recent peak, and the Composite 20 index off 2.0%.
Real House Prices
The second graph shows the same two indexes in real terms (adjusted for inflation using CPI less Shelter). Note: some people use other inflation measures to adjust for real prices. In real terms, the National index is 2.3% below the recent peak, and the Composite 20 index is 3.0% below the recent peak in early 2006.
In real terms, house prices are still above the bubble peak levels. There is an upward slope to real house prices, and it has been over 16 years since the previous peak, but real prices are historically high.
In October 2004, Fed economist John Krainer and researcher Chishen Wei wrote a Fed letter on price to rent ratios: House Prices and Fundamental Value. Kainer and Wei presented a price-to-rent ratio using the OFHEO house price index and the Owners' Equivalent Rent (OER) from the BLS.
Note that OER is lagging behind other measures of recent rent increases.
Here is a similar graph using the Case-Shiller National and Composite 20 House Price Indexes. This graph shows the price to rent ratio (January 2000 = 1.0). The price-to-rent ratio had been moving more sideways but picked up significantly following the onset of the pandemic.
On a price-to-rent basis, the Case-Shiller National and Composite 20 indexes declined again in August for the third consecutive month. The price-to-rent index for the National index is off 3.1% from the recent peak, and the Composite 20 based index is off 3.8%.
By all of the above measures, house prices are elevated.
Calculated Risk Affordability Index
I used median income from the Census Bureau (estimated 2021 and 2022), assumed a 15% down payment, and used a 2% estimate for property taxes, insurance and maintenance. This is probably low for high property tax states like New Jersey and Texas, and too high for lower property tax states. If we were including condos, we’d also include HOA fees too (this is excluded).
For house prices, I used the Case-Shiller National Index, Seasonally Adjusted (SA).
Also, for the down payment - there wasn’t a significant difference between 15% and 20%. For mortgage rates, I used the Freddie Mac PMMS (30-year fixed rates).
So here is what the index looks like (lower is more affordable like the FirstAm index):
Affordability improved slightly in August as both house prices and mortgage rates declined.
Note that by this index, during the early ‘80s, homes were very unaffordable due to the very high mortgage rates. During the housing bubble, houses were also less affordable using 30-year mortgage rates, however, during the bubble, there were many “affordability products” that allowed borrowers to be qualified at the teaser rate (usually around 1%) that made houses seem more affordable.
Note: The average 30-year mortgage rate in August was 5.22%, and the current rate is 7.14%, so affordability will be much worse in October.
