The uptick in the cost of home loans reflects a rise in the bond yields that lenders use as a guide to price mortgages, specifically the yield on the US 10-year Treasury. The yield on the 10-year Treasury has climbed from 3.62 percent in mid-September to 4.66% this week.

Fourth week of higher rates comes after 10-year Treasury yields, which mirror mortgage rates, rose after new economic data released this week pointed to stickier inflation and more job openings.

Mortgage interest rates pulled back a little this week, but it was hardly enough to erase the past three weeks' gains. The week ending Jan. 9, the average rate on the 30-year fixed-rate mortgage fell four basis points to 6.93%, according to rates provided to NerdWallet by Zillow. A basis point is one-one hundredth of a percentage point.

The average long-term U.S. mortgage rate ticked up again this week, remaining at its highest level since July. The benchmark 30-year fixed rate loan rate rose to 6.93% from 6.91% last week, according to mortgage giant Freddie Mac.

Mortgage rates continued to climb this week, with the 30-year fixed rate notching up toward 7% while housing demand remains stalled amid elevated rates and home prices.

Mortgage rates jumped to a six-month high of 6.93%, up from 6.91% last week, for the average 30-year fixed home loan for the week ending Jan. 9, according to Freddie
