What refinancing could save in Southold

Southold owners with a mortgage pay a median $3,373 a month for their mortgage, taxes, insurance and utilities, about 22.0% of their household income.

Say you owe $507,000, 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 $3,759 to $3,411, saving about $349 a month.

Closing costs often run 2% to 5% of the loan. At 3%, about $15,200, 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 $4,403, but you'd pay $435,357 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%.

Refinancing a $507,000 balance

New 30-year loan at 7.11%$3,411
New 15-year loan at 6.45%$4,403
