| House prices in the Philadelphia region: are they affordable yet?
Overheard at a recent ULI conference: "This slump will be over when people can afford to buy houses again." This simple, seemingly glib statement may best summarize the housing market's prospects for recovery.
So how affordable is housing in the Philadelphia market?
To answer this question, Rich Wilson and Jason Duckworth of Arcadia recently examined house prices relative to household income and rents over the last 20 years in the Philadelphia region.
House prices in the Philadelphia MSA increased more than 11.8% per year from 2000 to 2007, while median household incomes only rose 3.6% per year, according to data from the Census Bureau. Whereas the median house price was 2.6x the median household income in 2000, by 2007 it was more than 4.1x median household income.
Rent growth also substantially lagged house price growth in the same period, increasing only 2.7% per year according to HUD (3-BR fair market rent). Consequently, house prices went from about 11x the average 3-BR rent in 2000 to more than 18x in Q2 2008.
Will house prices revert to their historic relationships with household incomes and rents? We think so. We do not see any reason to believe that the fundamentals of housing economics were rewritten during the run-up early this decade.
But don't expect any sudden corrections. For the overall region, the history of the early '90s downturn suggests that any affordability adjustment may be slow and driven more by rising household incomes than by falling nominal house prices (i.e., a long slow bleed). New home builders and their bankers should be able to move faster to find market-clearing prices that will have more in common with year 2000 than with the giddy heights of 2005.
