Mortgage interest rates have increased today, though not by much. According to Zillow, the average 30-year fixed rate has risen by five basis points to 6.59%, and the 15-year fixed rate is up four basis points to 5.91%. Rates have probably inched up in anticipation of the Bureau of Labor Statistics releasing new inflation data today.While mortgage rates hold relatively steady, home prices continue to rise. In December, the median home price increased by 6% from the end of 2023 to $404,400, marking the 18th consecutive month of year-over-year price gains and the largest annual growth since October 2022. It may be a good time to lock in a rate and buy a house before the busy spring home-buying season gets underway.Have questions about buying, owning, or selling a house?
