Pending US home sales fell 1.7% in October amid short supply

WASHINGTON — Americans signed fewer contracts to purchase homes in October, as would-be buyers struggled to find available properties.

The National Association of Realtors says its pending home sales index, which measures the number of purchase contracts signed, fell 1.7% last month. The signed contracts become final purchases 1-2 months later.

Still, declining mortgage rates over time have lifted home sales. The index is up 4.4% from a year ago.

Mortgage rates have fallen sharply in the past year, partly because the Federal Reserve has lowered its benchmark short-term interest rate. That has partially offset steady increases in average home prices across the nation.
