Although, I am normally a big supporter of home ownership, this is not a good time. Yes the market is down, but real estate trends are long term and this bust could easily last another 5-6 years.
Even though the formally hottest markets....Southern California, the greater Las Vegas area, Phoenix, and Florida have corrected a good deal, they are still twice as high as in the year 2000. The Midwest, Texas, and the Northeast are reasonably stable.
Romanowski's advice on buying if you plan to stay for 3+ years is sound.
Real estate has been in a huge bubble and bubbles always end badly {Think Aces Gold}. You are absolutely not going to get hurt if your rent for the next year or two. Shop, save, keep your powder dry and find yourself a great house dirt cheap when there is blood in the streets. Just remember you have plenty of time.
