Why It's Not Correct That Real Estate Can't Be Analyzed In Real Time and Why It's Important

``Realtors have real time market data. They don't release it to the public. CoreLogic has access to real time contract data and they use that to publish a "pending sales price index with about a 3o day lag. Listing price trends are public and real time, and they are accurate reflectors of the market's direction. You can find them published at DepartmentofNumbers.com. They are above the absolute price level, but the ask is as good a market indicator as the bid. Sellers in the aggregate are not all greedy idiots. Serious sellers get direct market feedback and price their properties to sell. Asking prices rise and fall with the bids. The subsequently reported sales prices have consistently confirmed the accuracy of listing price trends. The spread is even relatively consistent at around 10% give or take a point or two.  If you know listing prices are rising or falling right now, are you willing to wait 5 1/2 months for confirmation?''
