The Inflation Connection
Mortgage rates are closely tied to inflation. When inflation runs high, the Federal Reserve raises interest rates to cool the economy — which pushes mortgage rates up and increases your monthly payment. A 1-point rate increase on a $600,000 loan adds approximately $417 to your monthly payment. Tracking inflation helps you understand where mortgage rates may be headed.
