The MS Access GSE CY 2012 public use single family database, with data to the census tract level, is available as a zip file HERE. The web page with all GSE CY 2012 data is HERE.
My post with CY 2012 SF data from last year, which included an Oregon Excel workbook, is HERE.
Readers may recall that posting of GSE SF data in MS Access formats occurred because of the actions of Senator Merkley, and his senior adviser Will White.
