The 30-year fixed mortgage rate on Zillow Mortgage Marketplace is currently 4.31 percent, up three basis points from 4.28 percent at this time last week. The 30-year fixed mortgage rate hovered between 4.2 and 4.27 percent early last week before rising to the current rate this morning. “Rates remained steady for the second week in a row, alleviating some concerns that they would continue the upward surge that began early this summer,” said Erin Lantz, director of Zillow Mortgage Marketplace. “This week, although we expect continued volatility, we expect rates will remain fairly steady until a clearer picture emerges about the strength of the U.S. economic recovery.” Zillow’s real-time mortgage rates are based on thousands of custom mortgage quotes submitted daily to anonymous borrowers on the Zillow Mortgage Marketplace site, and reflect the most recent changes in the market. These are not marketing rates, or a weekly survey. The rate for a 15-year fixed home loan is currently 3.32 percent, while the rate for a 5-1 adjustable-rate mortgage (ARM) is 3.16 percent.
