Is it worth it?
A break-even of 30 months is moderate. It works if you're fairly confident you'll stay in the home and keep this loan for more than 3 years; if a move or another refinance is likely sooner, the costs may outweigh the savings. Lower closing costs would shorten it.
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.
