We have added summary graphs for the home page. The graphs track the median price per locality. Even within a given locality, price swings are extreme. Median price value seems to be the more sensible way to present this data. However, since these are median prices, they will not reflect the prices of the highest end apartments or the lowest end apartments. These graphs are suitable to watch trends in the market.
Also as we gather more data and the graphs become coarse grained, the volatile swings in prices would go down. These graphs are plotted on a daily basis now, hence the crazy price swings. Once we move past this and go towards weekly reporting, the results would be much more smoother.
For absolute values of properties, one should use the search functionality. Search results can now be viewed as graphs as well.
