What denial? The lenders are in it for the money and they will stop using appraisers altogether as soon as they can get away with it.
And yes, some of the decisions they're making very well may turn out poorly for the taxpayers.
You are in denial about the link between GSE influence wrt laws and policies, which are bent and changed to disenfranchise appraisers and appraisals to financially benefit the lenders.
Now, if the lenders were loaning their own money, nobody could have a say in it. But the lenders are lending government taxpayer-backed money, and the GSEs are the gatekeepers to lenders for those loans. The lenders do not have a stated mission of public trust, but the GSE;s have it.
WRT your comment "as soon as they can get away with it" - again, since the lenders are profiting by being allowed to make loans at rates and terms backed by US taxpayers, they should not be "allowed to get away with it "- the GSEs are allowing them to get away with it with waivers which eliminate the appraisal.
Alternate valuation products might substitute for an appraisal, but they do not substitute for the ROLE of the appraiser - the one non-vested interest in the transaction. Becuse of that supposled to be indpenent, non vested intersts gives the appraiser the ability to "kill a deal" - by simply doing hteir job ....the attack on appraisers to marganaiie them has been non stop, and it includes the GSE;s turning a blind eye to the effects of the AMC;s- and if yu want to say it is not the GSE's job to protect the appraiser;s fees.....that is BS becaue appraisers can not function or train the next generain with such sub par fees and the AMC s simply passing the lnder pressure along.
This resulted in a predictable decline of appraisers , then the GSEs and lenders use the declining numbers as an excuse to find alternatives. If you want to close your eyes to the deliberate connection, then so be it.
While never addressing the predation of AMC fees on the appraiser, the GSEs made it their business to protect the RE agents' brokerage fees - when they decided, after the consumer lawsuit wrt RE brokerage fees, the GSEs sent letters to the lenders that the GSEs or lenders need not consider the seller paying a buyer brokerage fee as a covered concession. This in practice neutered the reason for the lawsuit, which was to reduce RE brokerage fees. to borrowers.
The GSEs like to point out the money borrowers saved with appraisal waivers, while their decisions wrt RE broker fees as outside of a covered concession will cost the consumer hundreds of billions more than the relatively smaller amount saved with waiver relief of the appraisal fee.
