where to find Home sells data and graphs?

[Ryan Standage]

im looking for any resources preferably online where i can find the number of home sells (new builds and used) in my area (phoenix, az). what would really help is if i could find a bar graph that would plot the number of home sells each month for the last couple of years.

the phoenix market recently experienced a boom and the housing prices soared through the roof, however they are now slowly coming back down and i am ready to buy, however i think the prices will continue to fall alittle more and i could profit a little more from my purchase if i hold out and wait longer. I am hoping this information from the number of home sells each month will help to determine the best time to buy.

if anyone knows where i can find this information it would be greatly appreciated
thanks
