Overall, Friday has the best potential to be the most active day for mortgage rates due to the GDP release, but Thursday may be pretty active also. The calmest day could be Tuesday. Besides the economic releases and auctions, we also will be watching corporate earnings. There is a high number of companies reporting, including big names such as Google, Facebook, AT&T, Boeing and Amazon. Surprises in some of those earnings figures can heavily influence stocks, causing funds to move into or away from bonds. With so much on tap this week that may influence mortgage rates, it would be prudent maintain contact with your mortgage professional if still floating an interest rate and closing in the near future.
