6 Good Reasons to Buy a Home Now

1. Prices have nearly hit bottom.

In most areas, most of the excess has finally been wrung out of the market.

But if you're buying a first home or looking to trade up, there's no need to rush. Although prices may fall some more -- blame foreclosures still working their way through the system and tighter credit -- they won't fall by much. Fiserv Case-Shiller, which tracks home prices, forecasts that the median price nationwide will ratchet down for about six more months, then stay flat for three or four years.

In most of the cities where home values experienced a double dip after the expiration of the homebuyer's tax credit in mid-2010, median prices won't fall below their 2009 or 2010 lows, says David Stiff, Fiserv's chief economist. These metropolitan areas include San Francisco, San Jose, San Diego and Washington, D.C. But in areas with a lingering oversupply of homes for sale, Fiserv forecasts a decline of 10 percent or more in the median home price (for the year ending March 31, 2012). These metropolitan areas include Riverside–San Bernardino, Calif.; Las Vegas; and Miami.   

2. Houses are affordable again.

Homes haven't been this affordable since 1991. Economists often define affordability as the ratio of median home price to median family income. According to Fiserv Case-Shiller, the U.S. ratio now stands at 2.6 -- down from a peak of 4.1 in mid-2005 and just under the long-term average of 2.8. Of course, some areas continue to defy affordability. In California's coastal cities and the New York metro area, the ratio is 5 or more. Average mortgage payments are another way to look at affordability. Since the housing market's peak in 2006, the average principal-and-interest payment in the U.S. has fallen from $1,063 to $645.

Renters considering the jump to homeownership may be encouraged by the price-rent ratio, or the median home price divided by the median annual rent. In 2005, the national median home price had inflated to nearly 21 times the median annual rent. Since the bust, the ratio has deflated to 14, less than the historical average of 15. During the same period, the difference between the median monthly mortgage payment and median monthly rent fell from $745 nationally to $102. Expect rental vacancy rates to hit pre-­recession levels this year, allowing landlords to raise rents by an average of 3.5 percent.

3. Mortgage rates won't go any lower.

For the past couple of years, interest rates have hovered at levels last seen when the veterans came home from the Korean War. According to HSH.com, which tracks mortgage rates, at the beginning of August the national average 30-year fixed rate was 4.5 percent. FHA loans, which require only a 3.5 percent down payment, had a 4.3 percent rate. Adjustable-rate mortgages are even cheaper, and even rates for jumbo mortgages have hit lows not seen since the 1980s.

Freddie Mac forecasts a 30-year fixed rate of 5 percent by year's end and 6 percent by late 2012. Standard & Poor's downgrade of the U.S. credit rating won't have an immediate effect on rates because of the weak economy (see Ripple Effects of the U.S. Debt Downgrade). But credit is tighter, and you'll need a credit score of 740 or more and a down payment of at least 25 percent to nab the lowest rates. If you fall short of that, you'll pay interest-rate risk premiums if the bank plans to sell your loan to Fannie Mae or Freddie Mac. For example, lenders must charge an extra 0.25 point if a borrower has a 740 credit score but puts down less than 25 percent (but at least 20 percent).

4. It's a buyer's market.

Demand is low; supply is high. In early summer, the National Association of Realtors reported that sales of existing homes (single-family houses and condos) fell by 9 percent from the year before. NAR also reported 9.5 months' supply of homes. That's how long it would take to sell all the homes on the market at the current pace of sales, and it strongly favors buyers. (Four to six months' supply is considered balanced between buyer and seller.)

With so much selection, you'll find more properties in good school districts or near your job, or homes that offer added value, such as a mother-in-law suite, says Thomas Popik, research director with the Campbell surveys of real estate professionals. You'll spend less time shopping and competing against other bidders. And you don't have to waste time with sellers who set unrealistic prices (although they're still out there).

One caveat: If you're searching among entry-level homes, which had more extreme price declines than upper-end houses did over the past year, you may face stiff competition from investors. They typically pay cash, which makes them attractive to sellers who want to close the deal fast. However, says Popik, you may find opportunities in homes that were bought and fixed up by investors, who intended to flip them but have had difficulty making a sale.

5. You may find a distressed property.

Bank-owned foreclosures (or REOs, for "real estate owned" properties) sell for an average discount of 35 percent off the per-square-foot price of conventional homes for sale, according to RealtyTrac. In the first half of 2011, lenders owned about 870,000 REOs but listed only about one-fifth of them for sale, concentrated in such high-foreclosure states as Arizona, California, Florida, Michigan, Nevada and Ohio; even with the slowdown in the foreclosure pipeline due to legal-processing issues and new supply exceeds sales.

Short sales, or homes sold with lenders' permission for less than their owners owe on their mortgages, have also grown in number. Lenders have become more amenable to them as they seek to avoid the often huge losses associated with foreclosures, says Rick Sharga, of RealtyTrac. Short sales offer buyers less of a bargain than REOs, but the homes tend to be in better condition. Banks may still take two to six months to sign off on a short sale, so patience is imperative.

6. Homeownership is still attractive.

A home is the biggest purchase most people ever make. But deciding whether and what to buy isn't purely a financial decision, says Chris Herbert, research director at Harvard's Joint Center for Housing Studies. When you own a home, you can control your living environment and security, upgrade and change your home as you see fit, and create a sense of rootedness in your community.

You can offset some of the cost of homeownership by deducting mortgage interest. But don't mistake a home for an investment, at least not in the short run. "If your goal is to jump in and get a return of 6 percent annually, that's a bad idea," says Fiserv's Stiff, given the forecast for weak price appreciation. Instead, you need to commit to owning the home for at least five to seven years to ride out any further price declines and recoup your down payment and transaction costs. If you think that you might need a bigger home before that time to accommodate a growing family or that you might have to move to another area for your job, don't buy unless you're willing to become a long-distance landlord.

Shop carefully, and be patient. Exclusive buyer's agent Michael Crowley of Spokane, Wash., tells buyers it may take three to four months to find the right house. "We can be in a hurry, or we can be particular, but we can't be both," he says.
