A number of key mortgage rates advanced in the Boston area this week.

Benchmark 30-year rate up in Boston

The average rate on the benchmark 30-year fixed-rate mortgage rate for the Boston area rose to 4.00 percent, according to Bankrate’s national survey of large lenders. While the local rate was up 7 basis points from last week, it was lower than the national average rate of 4.09 percent. A basis point is one-hundredth of 1 percentage point.

For mortgages in this week’s survey, there were an average of 0.22 discount and origination points.

With the 30-year fixed rising, it means that homebuyers and refinancers will find it more costly to borrow.

The rise in the mortgage rate elevated 30-year fixed-rate monthly payments on a hypothetical $165,000 mortgage to $787.74, an increase of $6.67 from last week.

Other Boston mortgage types see increases

The rate for 30-year jumbo mortgages also rose this week, ticking up 6 points to 3.95 percent. Jumbo mortgages are used for loan amounts above limits set by the Federal Housing Finance Agency; for the Boston area, that limit is $598,000.

The average rate for 15-year fixed-rate mortgages ticked upward to 3.30 percent, rising 6 basis points from last week. Monthly payments on a hypothetical $165,000, 15-year fixed-rate mortgage moved up with rates, ticking up $4.83 to $1,163.42.

Because the 15-year fixed is a popular mortgage for homeowners who want to refinance, the increase means that a refi is less beneficial than it would have been before the rate rise.

The popular 5/1 adjustable-rate mortgage rate increased to 3.57 percent this week, a rise of 9 basis points. 5/1 adjustable-rate mortgages allow homeowners to pay a fixed rate for the first 5 years, and the rate adjusts once per year every year after. They are the most popular type of variable-rate mortgage.

Methodology: The “Bankrate.com National Average,” or “national survey of large lenders,” is conducted weekly. To conduct the National Average survey, Bankrate obtains rate information from the 10 largest banks and thrifts in 10 large U.S. markets. In the Bankrate.com national survey, our Market Analysis team gathers rates and/or yields on banking deposits, loans and mortgages. We’ve conducted this survey in the same manner for more than 30 years, and because it’s consistently done the way it is, it gives an accurate national apples-to-apples comparison.
