What refinancing could save in Clarendon Hills
Clarendon Hills owners with a mortgage pay a median $3,379 a month for their mortgage, taxes, insurance and utilities, about 22.3% of their household income.
Say you owe $363,000, 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 $2,691 to $2,442, saving about $250 a month.
Closing costs often run 2% to 5% of the loan. At 3%, about $10,900, 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 $3,152, but you'd pay $311,704 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%.
| Current loan at 8.11%, 30 years | $2,691 |
|---|---|
| New 30-year loan at 7.11% | $2,442 |
| New 15-year loan at 6.45% | $3,152 |
| Monthly savings with the new 30-year loan | $250 |
Principal and interest only; taxes and insurance stay the same.
