According to Trulia, another bubble is far away, with home prices still undervalued:

We estimate that national home prices are 5% undervalued in the third quarter of 2013. During last decade’s housing bubble, prices were as high as 39% overvalued in 2006 Q1, then after the crash fell to 15% undervalued in 2011 Q4. One quarter ago prices looked 7% undervalued; one year ago prices looked 14% undervalued, Trulia reported.
