Housing was slightly less affordable in November.

An index measuring the ability of a typical family to buy a home edged down to 107.9 in November, off from a nine-year high of 108.5 in October, the National Assn. of Realtors reported. The index has been above 100 since June. The November figure means that a family earning the median income of $29,078 had 107.9% of the resources needed to qualify for a mortgage covering 80% of the median price of a home, which was $80,900 in November.
