Ever heard the old rule of thumb, you should only refinance if your new interest rate is at least two points lower? That may have been true years ago, but with refinancing dropping in cost over the last few years, it's never the wrong time to think about a new loan! Refinancing has a number of benefits that often make it worth the up-front expenditure many times over.

When you refinance, you might be able to lower your interest rate and monthly payment -- sometimes significantly. You might also be able to "cash out" some of the built-up equity in your home, which you can use to consolidate debt, improve your home, take a vacation -- whatever! With lower rates and balances, you might also be able to build up home equity faster with a shorter-term new mortgage.

All these benefits do cost something, though. When you refinance, you're paying for most of the same things you paid for when you obtained your original mortgage. These might include settlement costs and other fees, an appraisal, lender's title insurance, underwriting fees, and so on.
