Totally agree with TG. If your mortgage is < or = rent and you're buying a home, not an investment, then I'm bullish. If you plan to buy and rent it out and your PITI cost is <50% of rent, I'm bullish there too. The lower the mortgage vs rent, the more bullish I am. As SD Realtor have point out before, areas that have extremely low Sale/Supply ratio or Pending/Supply ratio are very bullish to me as well. When you have 2 months supply, I think that's pretty bullish signal.
