What I read is that overall home prices are off by 2.5% in the past 12 months. The Dataquick sales data shows East County median prices up slightly, Central SD down slightly, and North County prices flat since last year.
Month to month sales can vary a lot – but if you want to measure everything in the future off of one month, (11-05) go ahead, but it’s not going to be terribly accurate. In my opinion, the best way to measure the overall market is to report the median price of all of the SFR sales in a calendar year, and compare against the median price of all sales from another calendar year.
Also, when the UT lumps condos in with SFRs as they did in their on-line article, I would guess that all of the condo coversions are depressing the median price slightly when comparing against prior years.
