What refinancing could save in Butte County

Butte County owners with a mortgage pay a median $1,694 a month for their mortgage, taxes, insurance and utilities, about 20.4% of their household income.

Say you owe $147,000, about 60% of the median home value here, on a 30-year loan at 8.11%. Refinancing into a new 30-year loan at this week's average of 7.11% would cut principal and interest from $1,090 to $989, saving about $101 a month.

Closing costs often run 2% to 5% of the loan. At 3%, about $4,400, the savings would cover the costs in about 44 months, so refinancing pays off if you keep the home longer than that.

A 15-year loan at 6.45% would raise the payment to $1,276, but you'd pay $126,229 less interest than on the new 30-year loan.

The average 30-year rate is 0.87 percentage points higher than a year ago, when it was 6.24%.
