I would SERIOUSLY think twice about buying a house in this economy.
Here are some links that should give you an idea of how much money you might lose over the short term.
Definately watch the first one.. EVERY future home buyer should watch this:

This site will give you current trends in MLS (for the last 6 months) so basically.. if it said -6% .. You would have lost 6% of the value of your home in just a couple months. On a 300K home, that's 18K.

This site can track affordibility for your city. When mortgage/rent is above 1.0, then Mortgage > Rent for comparable homes. In this case, you should look into just renting the home from the silly owner. If your city is below 1.0, it's cheaper to buy than to rent. However, I would still wait at least a year for the markets to cool down. You'll get in at a better price point.

This site picks up the latest housing news. It should help you figure out when things are starting to get better.

If you decide to be silly and buy in the current market, buy 2-3 x Family Income. Don't be one of those dopes in the first link that bought a 500K home only for their neighbors to buy their home at 290K.

Lastly, I check up on how the general market and economy is doing using:

And remember, real estate doesn't have to go up. And with 1million homes added even in 07.. There is too much inventory for prices to go up. They will only go down.
P.S. The Northwest of the US is lagging the rest of the US by about 3-5 months. They are headed down too.
