After the kitchen, you may want to think about remodeling your existing bathroom. If your house is older, you may be sporting pink, blue or avocado tile or outdated fixtures. Even if your home is newer, styles can change. Invest in neutral-colored tile and give the room some personality with a fresh coat of paint, wall hangings and a new shower curtain. Update lighting fixtures and install a low-flow toilet to save on the water bill. You may even want to add a new vanity and matching mirror.

Home-equity lines of credit. These mortgages work kind of like credit cards: Lenders give you a ceiling to which you can borrow; then they charge interest on only the amount used. You can draw funds when you need them — a plus if your project spans many months. Some programs have a minimum withdrawal, while others have checkbook or credit-card access with no minimum. There are no closing costs. Interest rates are adjustable, with most tied to the prime rate. Most programs require repayment after 8 to 10 years. Banks, credit unions, brokerage houses, and finance companies all market these loans aggressively. Credit lines, fees, and interest rates vary widely, so shop carefully. Watch out for lenders that suck you in with a low initial rate, then jack it up. Find out how high the rate rises and how it's figured. And be sure to compare the total annual percentage rate (APR) and the closing costs separately. This differs from other mortgages, where costs, such as appraisal, origination, and title fees, are figured into a bottom-line APR for comparison.
