Getting Graphic is a semi-sort-of-irregular collection of our favorite BIG real estate-related chart(s).
In the national market, inventory increased this month [WSJ]  (free version ) according to ZipRealty , which is normally “normal” except that this time, the increase was unusually high. Of course, I have no idea what the actual inventory levels are from ZipRealty because there are no numbers in this article. The reader has no sense of the size of the sample or how representative ZipRealty is of the market.
These stats are 100 percent, ahem, percent-driven.
NAR reported 3.748M houses for sale in February , up 5.9% from January so 6.5% in March by ZipRealty doesn’t really seem that inconsistent with what we are already seeing.
If we accept that ZipRealty represents the market as a whole (which I am pretty sure it doesn’t), the reasoning was given that consumers feel it may take longer to market a property with higher inventory (very logical) so the houses are coming on the market a little sooner. However the Credit Suisse 22 year average of 1.7% increase over this period would contradict this theory since there have been plenty of periods with excess inventory over the past two decades. Something has got to be wrong with the CS stats – they strike me as severely understated.
Of course the other side of the coin to this argument is that sluggish sales levels are allowing inventory to back up. I am on the fence on this one, perhaps leaning toward the former and “buy” into the argument that sellers are anticipating longer marketing times.
In Manhattan, the situation is the opposite as of late  as indicated in my market survey, with inventory levels slipping , despite the fact the market is entering the spring selling season.
