Manage Your Mortgage
If you own a home, you've got both a huge debt and a very valuable asset. You can use a home to your advantage as both. If you're a young saver and own a home, it's a good idea to keep an eye on interest rates. If they begin to fall, consider refinancing your mortgage to a lower rate. Using any extra money that formerly went to the recurring monthly expense of your higher mortgage payment can then go towards your retirement savings contributions. It's a good idea to do the math first, however. Paying off mounting credit card debt will likely prove a better use for the extra income, since credit cards almost always have a higher rate than a home mortgage. If the opposite is true for you, refinancing your mortgage is definitely a good idea.
Avoid the temptation of taking out a second mortgage to consolidate your debt unless you trust your spending habits have been curtailed to fit a saving mentality and the cost of paying off your credit cards and other debt is more expensive than the additional mortgage payment each month.
Ultimately, the best thing you can do with your mortgage is to pay it off by the time retirement rolls around. The loss of a recurring monthly expense in the hundreds or thousands of dollars like a mortgage payment is an instant and substantial increase in income.
