With interest rates at all time lows, that has also brought mortgage rates down to all time lows. The 30-year fixed mortgage rate this week was at 3.18% while the 15-year is at 2.62%. However, banks and lenders have retained tight underwriting standards for home loans, pushing the average credit score above 700. This is causing younger buyers to delay their home purchase. The average credit score among buyers between the ages of 30 and 39 is 673, which disqualifies them from financing a home. Lenders have done this in order to reduce their risks and not put themselves in a position again like the 2008 housing crisis.
