Phoenix Business Journal:  New data from Arizona State University show foreclosures are becoming a smaller portion of the total home transactions in the Phoenix area.  The report from ASU’s W.P. Carey School of Business shows foreclosures represented about 35 percent of the existing home transactions in the Phoenix area in May.  That continued a decline from 43 percent in January and February, to 38 percent in March, to 36 percent in April.
