Double Bubble Trouble
Real estate data site PropertyShark.com has launched a new "Bubble Map" tool that highlights areas with a drop in the number of sales and areas with a drop in the value of sales. The company is launching the first Bubble Map today for the San Francisco market, with plans to launch a Bubble Map for New York City in February and Los Angeles in March. "We will then roll them out in other major cities," according to Brian Scully, vice president of marketing for PropertyShark.com.
On the Bubble Map, light blue-shaded areas note areas with single-bubble trouble (a drop in the number of sales or drop in the value of sales) and dark blue shading is used for areas with double-bubble trouble. A pink unhappy face icon signals a drop in sales value while a red unhappy face shows a drop in sales for a given area.
The sales drop is based on a lower number of residential sales transactions in the last full quarter compared to the average number of residential sales transactions for the previous eight quarters in a given zip code area. The value drop is based on a lower median residential sale price for the last full quarter compared to the median sale price for the last eight quarters for a zip code area.
Also, PropertyShark.com announced three additional new maps for the San Francisco market, including price per square foot, recent sales and year built.
