How Much Over List Price Do I Need To Offer?

Home buyers want to see the typical relationship between list price and sales price. This relationship varies with city, time, and price range. The plots below show this relationship for Santa Clara County houses and San Mateo County houses using color coding. Green areas in the top plot mean more homes are being sold over list price (which is a very good indicator of rising home prices). Red areas in the top plot mean more homes are being sold under the list price (which is a good indicator of falling home prices).

The top plot changes from a red area prior to 2012 to a green area after the beginning of 2012 marking the start of a solid recovery from the 2007 economic problems. This plot is a good way to see changing market conditions.

The lower plot shows the percentage that the average sale was either over or under list price.

Average and Median Price of Santa Clara County and San Mateo County Houses Sold

When trying to understand home values the first and most often real estate statistic looked at is either average or median home sales price. The average price can be pushed up by a particularly expensive home being sold. Much less often an especially low price for one or two homes can push the average price down. By looking at both average and median price a quick judgment can be made about any unusually high or low prices. Just after the beginning of 2012 both the average and median prices rose and continued a bumpy climb upwards. The sales price vs. list price in the preceeding section showed a pretty clear change in behavior at the beginning of 2012.

If the size of the average home changes, the average sales price can be affected even though the price per square foot has not changed. This can easily happen when a new large townhouse or condo development starts selling.
