1. Change your mortgage term

If you decrease the term of your mortgage in a refinance by going from a 30-year to a 15-year, you’ll pay a lower interest rate and shorten your total interest costs. You’ll build home equity more quickly, and pay off your loan sooner, even though your monthly payments go up.

2. Move from an adjustable rate to a fixed rate

ARMs offer low introductory rates, but they also offer long periods of uncertainty that make it hard to budget. It makes sense in a mortgage refinance to go from an ARM to a fixed-rate loan during a low-interest rate environment. You’ll get emotional security and your rate won’t fluctuate with changing economic conditions.

3. Take out cash

With a cash-out mortgage refinance, you can turn an intangible asset—accumulated home equity—into a tangible one—cash. It makes sense for a project that will generate long-term benefits, like a home improvement or funding a child’s college education. However, don’t do it for frivolous reasons. Unless you’re extremely disciplined, you could find yourself in even deeper debt.

4. Consolidate two mortgages

When interest rates are low, a mortgage refinance lets you consolidate your main mortgage and an outstanding home equity loan to realize a lower overall monthly payment. Plus, you’ll have only one mortgage payment to make each month.

5. Recover from divorce

If your home is jointly owned with your soon-to-be ex-spouse, a mortgage refinance will turn a joint obligation into the responsibility of the person keeping the home. Nothing is more frustrating than tracking down a former spouse who doesn’t keep up with his or her end of the mortgage payment.

Lay the groundwork

If one of these reasons resonates with you, contact your current lender to see if it’ll offer you preferred rates or reduced closing costs on a mortgage refinance. But don’t assume the current lender is best: Leave no stone unturned by searching for lenders online and calling community banks and local credit unions.

No matter which lender you choose, a mortgage refinance for the right reasons can save you lots of money—and that’s the best reason of all.
