The National Association of Realtors reported that its Composite Index of Home Affordability declined 10.6% y/y during November to 144.0. The index was one-third below its peak in January 2013. Month-to-month, home affordability declined 2.0%.

Together, principal & interest payments of $1,117 rose m/m to 17.4% of median income from 15.5% twelve months earlier. These percentages compare to a low of 11.6% early in 2013. Higher prices helped reduced affordability during the past year. The median sales price of an existing home strengthened 5.0% y/y to $260,500. The average mortgage rate rose to 4.99% in November, up from a 3.43% low in December 2012. Growth in median family income slowed to 3.0% y/y in November from 4.0% during all of last year.

The Housing Affordability Index equals 100 when median family income qualifies for an 80% mortgage on a median priced existing single-family home. A rising index indicates more buyers can afford to enter the home-buying market. Data on Home Affordability can be found in Haver's REALTOR database. Interest rate data can be found in the WEEKLY and DAILY databases.
