1. Tax breaks. The U.S. Tax Code lets you deduct the interest you pay on your mortgage, your property taxes, as well as some of the costs involved in buying your home.

2. Appreciation. Real estate has long-term, stable growth in value. While year-to-year fluctuations are normal, median existing-home sale prices have increased on average 6.5 percent each year from 1972 through 2005, and increased 88.5 percent over the last 10 years, according to the NATIONAL ASSOCIATION OF REALTORS®. In addition, the number of U.S. households is expected to rise 15 percent over the next decade, creating continued high demand for housing.

3. Equity. Money paid for rent is money that you'll never see again, but mortgage payments let you build equity ownership interest in your home.

4. Savings. Building equity in your home is a ready-made savings plan. And when you sell, you can generally take up to $250,000 ($500,000 for a married couple) as gain without owing any federal income tax.

5. Predictability. Unlike rent, your fixed-mortgage payments don't rise over the years so your housing costs may actually decline as you own the home longer. However, keep in mind that property taxes and insurance costs will increase.

6. Freedom. The home is yours. You can decorate any way you want and benefit from your investment for as long as you own the home.

7. Stability. Remaining in one neighborhood for several years gives you a chance to participate in community activities, lets you and your family establish lasting friendships, and offers your children the benefit of educational continuity.

Paul Cardis, CEO of AVID Ratings Co., which conducts an annual survey of home buyer preferences, said there are 10 "must" features in new homes:

1. Large kitchens, with an island. "If you're going to spend design dollars, spend them where people want them-spend them in the kitchen," McCune said. 2. Granite countertops are a must for move-up buyers and buyers of custom homes, but for others "they are on the bubble," Cardis said.

3. Energy-efficient appliances, high-efficiency insulation and high window efficiency. Among the "green" features touted in homes, these are the ones buyers value most, said Cardis. While large windows had been a major draw, energy concerns are giving customers pause on those. The use of recycled or synthetic materials is only borderline desirable.

4. Home office/study. People would much rather have this space rather than, say, a formal dining room. "People are feeling like they can dine out again and so the dining room has become tradable," Cardis said. And the home theater may also be headed for the scrap heap, a casualty of the "shift from boom to correction."

5. Main-floor master suite. This is a must feature for empty-nesters and certain other buyers, and appears to be getting more popular in general. That could help explain why demand for upstairs laundries is declining after several years of popularity gains.

6. Outdoor living room. The popularity of outdoor spaces continues to grow, even in Canada. The idea of an outdoor room is even more popular than an outdoor cooking area, meaning people are willing to spend more time outside.

7. Master suite soaker tubs. Whirlpools are still desirable for many home buyers, but they clearly went down a notch in the latest survey. Oversize showers with seating areas are also moving up in popularity.

8. Stone and brick exteriors. Stucco and vinyl don't make the cut.

9. Community landscaping, with walking paths and playgrounds. Forget about golf courses, swimming pools and clubhouses. Buyers in large planned developments prefer hiking among lush greenery.

10. Two-car garages. A given at all levels; three-car garages, in which the third bay is more often than not used for additional storage and not automobiles, is desirable in the move-up and custom categories.
