Is it worth it?
A break-even of 59 months is long. You'd need to keep the loan more than 5 years to come out ahead, so this refinance makes sense mainly if you're settled long-term or can get closing costs well below 2%.
Shorter terms raise the payment but cut lifetime interest sharply. Want the background? Read is it worth refinancing for 1%, or check your own costs with the break-even calculator.
