I have to disagree with the assessment that it's a bad time to buy. The Fed has just promised to print 1 TRILLION dollars to buy mortgage securites (basically) and that really changes thing. This level of printing is totally unprecedented since the Continental, even in the New Deal, WWII, or the 70's. Primarily, it guarantees significant inflation in 1-3 years, and inflation might exceed 20% a year. No doubt the Fed will try to dial things back, but between losses on the securities they're buying and an unemployment rate probably over 9% (maybe a lot over) their options will be limited.
That has two implications for housing. First, the really low interest rates now and in the near future will probably never be matched again. Instead, we can expect a massive increase in the next few years. Try 10% and up. Second, the decreases in the *real* value of houses (inevitable) will be compensated for by inflation. *Nominal* house prices, nationally, will probably bottom this year. So, if you can buy, and if you are *certain* you will stay for 5-10 years, it's now a good time to buy.
Of course details matter and so we can't say whether the particular house you're looking at is a good purchase without more info.
