Rebut what? Fannie and Freddie weren't formed to be feeding troughs to service residential appraisers.
The users of residential mortgage appraisal services (at this time mainly Fannie & Freddie) are moving forward. Meanwhile, too many residential mortgage appraisers are holding on to their Fannie 1004 forms and refusing to move forward. Just what do you think any appraiser org could or should do? Demand Fannie and Freddie with their trillion dollar portfolios not move forward? Good luck with that.
Think C&R is the real fight? Well here's the cold hard reality: Fighting over fees for products that are being replaced is not only short sighted, it will likely be the final nail in the coffin for many residential appraisers who depend on mortgage origination assignments.
The AI website does show documents related to what issues are and what concerns are being addressed. The announcement from Fannie and Freddie just came out a day or two ago, although I suspect there has been some commentary and concerns expressed. The site shows online newsletters as well as advocacy records. Admittedly, the site can be a bit difficult to navigate. For newsletters, start here http://www.appraisalinstitute.org/ano/ for advocacy start here http://www.appraisalinstitute.org/advocacy/
The stress test issue is something of interest since if the GSEs would fail, it seems pretty reckless to take on more risk through not obtaining appraisals, and the cost of an appraisal is a drop in the bucket compared to other costs of a mortgage. The elimination of the one unbiased party makes absolutely no sense.
Hope all of the appraisal organizations come out strongly against this, however rather doubt it would have any effect on the reckless ways of the GSEs when money is to be made.
