The average 30-year fixed mortgage rate has risen to 6.22%, according to Freddie Mac, marking the third consecutive week of increases. This comes as the Middle East conflict continues to impact mortgage rates. The 15-year rate is also up for a second week in a row, at 5.54%, a 0.04% increase since last week. The longer the conflict drags on, the greater impact on mortgage interest rates could be. As rates rise during the conflict, consider getting an adjustable-rate mortgage (often called an ARM) instead of a fixed-rate loan. ARMs lock in an interest rate for the entire term length, then fluctuates at regular intervals. However, there is a risk that market rates could increase when your introductory-rate period ends and your monthly mortgage payment would increase.
