Washington CNN  —  US home-price growth accelerated in February at the fastest annual pace since November 2022, a sign that America’s housing market remains tough amid elevated mortgage rates. The S&P CoreLogic Case-Shiller National Home Price Index, a measure of home prices across the country, rose 6.4% in February from a year earlier, a bigger increase than the 6% registered in January. On a monthly basis, the index advanced a seasonally adjusted 0.4% in February.
