First, I’m glad you posted this data. I did the same for our old complex, but it was a smaller complex so less data points.
My question; how do you know the “peak” was sept 2005?
I suggest you run your data back to at least mid-2004. The peak pricing on our Rancho Bernardo condo was mid-2004. The condos peaked much earlier than the SFH’s. I think your data range may not extend far back enough in time to catch the peak.
