Mortgage rates continued their upward climb this week, with rates on 30-year mortgages rising to their highest point since mid-April.

Rates on 30-year fixed-rate mortgages rose to a nationwide average of 5.82 percent, up from 5.77 percent last week, Freddie Mac said Thursday.

It marked the fifth consecutive week that rates on 30-year mortgages rose. This week's increase left rates on 30-year mortgages at their highest since they averaged 5.91 percent for the week ended April 14.

Rates on 15-year fixed-rate mortgages, a popular choice for refinancing a home mortgage, averaged 5.38 percent this week, compared with 5.34 percent last week. This week's rate also was the highest since the middle of April.

For one-year adjustable-rate mortgages, rates rose to 4.47 percent, from 4.46 percent last week. This week's rate was the highest since one-year ARMs averaged 4.50 percent the week ended July 19, 2002.

Rates on five-year hybrid adjustable-rate mortgages averaged 5.30 percent this week, up from 5.27 percent last week.

The nationwide averages for mortgage rates do not include add-on fees known as points. Thirty-year mortgages and 15-year mortgages each carried an average fee of 0.6 point this week. One-year ARMs and five-year ARMs each carried an average fee of 0.7 point this week.

A year ago, 30-year mortgages averaged 5.99 percent, 15-year loans were at 5.40 percent and one-year ARMs averaged 4.08 percent. Freddie Mac does not have historical data on the five-year ARM, which it began tracking this year.
