Long-term mortgage rates fell dramatically Thursday in response to the Trump Administration tariffs that went into effect on Wednesday, according to Mortgage Daily News. The average rate on a 30-year fixed-rate mortgage fell 12 basis points to 6.63% during the week ended Thursday, April 3, 2025, down from 6.75% the week before and falling to the lowest level since October. The drop in rates could be a big boost to the spring housing market, where new listings jumped 10% annually in March.
