$160k median value increase in last 10 months!

People keep talking about a "double dip" recession, but what about a "triple peak bubble"?

Here is a link to the median trend chart for San Mareno:

The bubble started deflating later than other surrounding areas; and then due to other economic factors, continued bubbling.  But then the bubble deflation started hitting hard at then end of 2007 into 2009, until the government intervened with a $8k give-away.

But what did that $8k give away do?  Raise median prices by $160k?!  And the chart indicates still a steep increase, not flattened out yet (as of May...)

So, two questions; how much longer will it rise before it levels out and the bubble can actually start deflating?  And will the new peak exceed the previous peak?

Why worry about double dips?  It already occurred!  But a triple peak bubble?
How low does it need to go before the bubble factors are deflated?  Is the government going to intervene again so that it can be a quadruple peak bubble?
