WASHINGTON – An index measuring the number of Americans who signed contracts to buy homes in October jumped to nearly its highest level in almost six years. Steady job gains and record-low mortgage rates have made home buying more attractive.

The National Association of Realtors said Thursday that its seasonally adjusted pending home sales index rose 5.2 percent to 104.8 in October. Excluding a few months when the index spiked because of a homebuyer tax credit, that is the highest level since March 2007.

The increase points to healthy sales increases of previously occupied homes in the months ahead. There's generally a one- to two-month lag between a signed contract and a completed sale.
