US Mortgage rates fell for the second straight week, averaging 6.30% as of April 16, down from 6.37% last week, easing borrowing costs during the peak homebuying season. Rates hit a one-month low amid easing geopolitical fears and a record S&P 500, as strong bank and tech earnings overshadowed Middle East tensions. Refinance activity rose, per the Mortgage Bankers Association, while purchase applications stayed subdued, remaining below year-ago levels for the second week, as buyers remained cautious amid economic uncertainty.
