Confidence among U.S. home builders fell more than forecast in October to a four-month low as rising interest rates and the budget battle in Washington stifled progress in the housing market, according to the National Association of Home Builders/Wells Fargo index of builder sentiment, Bloomberg reported. Though the overall index dropped, home builder confidence in the Midwest posted a one-point gain, the only region of the country that reported higher confidence, according to a news release from the National Association of Home Builders.
