Brent Kalka, Certified Funds Specialist, or CFS, and financial adviser at Mueller Financial Services Inc., Elgin, Ill., points out there are times a person or couple should not consider buying in this market.

"For example, if a retired couple is thinking of selling their home in order to downgrade and gets less than fair market value, they will lose more financially then what they gain by getting a good deal on a less expensive house and are better off financially by waiting until the market turns around."

A second consumer who ought not consider changing residences is a homeowner who, prior to the market downturn, had 20 percent equity in their home and didn't have private mortgage insurance, or PMI payments.

"With home values down," he says "their equity has dropped, and they no longer would have the 20 percent down payment necessary in a lateral or upgrade purchase to avoid PMI, which can run anywhere from $50 to $150 per month."

Kalka also believes that potential homebuyers should consider the fact that the real estate market could be no better or even worse a year from now, so they have to decide if they want to wait it out.

People whose jobs are shaky should wait until their situation is more secure.

"To buy on what you are making now if future income is not stable is asking for trouble," Rose says.

Also, if you are experiencing a life change, such as an upcoming job transfer, getting married, planning to move geographically within the next two years or struggling financially, you should wait.

"People who are thinking of flipping a home should not buy," says Walter Molony, spokesman for the National Association of Realtors. "Housing is a long term investment, and if you're only planning to be there for a year or two, keep renting."

According to Karen L. DeRose, CFP, DeRose & Associates, Chicago, renovating and flipping homes is much harder today and not something she is recommending to any of her clients. She says several of her clients now have to sit on these properties and the gains they thought they would get have been eaten away by the decline in home prices.

People with heavy credit card debt should not consider buying now. "They must clean up their credit first," Chu says.

Should you buy a home in foreclosure?
The Census Bureau reported that the number of vacant homes in 2007 climbed to 2.8 million from 2.07 million. This is the biggest one-year jump on record. What does that mean to potential homebuyers?

Although property is available, Marsha Schwartz, a broker associate from Coldwell Banker Residential Brokerage in Northbrook, Ill., and Rose believe that buying a home in foreclosure can be a challenge and not always a good deal. Sometimes the home has been neglected for a long time due to financial reversals. Be prepared to invest money in the property.
