New GAO Report on GSE Multifamily Activity: 2011 Market Share was Double 2008 Market Share.

Haven't read in detail yet , but report is available from NCSHA site HERE.  Quick tidbits:

[GSE's]...financed less than 30 percent of annual multifamily loans originated before 2008 ...Their share of the multifamily market increased to 86 percent in 2009, but decreased to about 57 percent in 2011 as other participants reentered the market.

State table on PDF pages 90-91 shows $6.2 billion in GSE MF activity in Oregon from 1994-2011. (Recall that GSE's did $13.8 billion in SF loans in Oregon in CY 2011 alone).
