Three green houses on stacks of coins

The average cost of 30-year, jumbo mortgages and 15-year, fixed-rate home loans fell to new all-time lows this week, according to Interest.com’s most recent survey of major lenders.

The typical rate for a jumbo loan -- one that exceeds $417,000 to $729,750, depending on the city -- fell to 5.02%. The previous record low was 5.04% reached in November 2010.

The new low for 15-year financing was 3.61%, down from the previous record of 3.68% set just last week.

The results of our new survey continue an incredible summer for mortgage rates.

Three of the four types of loans we track -- jumbo, 15-year and 5-year adjustable-rate loans -- have all set new all-time lows in the past two weeks.

The only type of home loan that hasn't -- the 30-year, fixed-rate mortgage -- has fallen to within six-hundredths of a point of its record low set last November.
