Jeremy Bagot weighs in:
"VENTURA, Calif. (Dec. 20, 2024) – Ohio podcaster, real property appraiser and influencer Phil Crawford contends he has localized a “cancerous” home sale in a Cincinnati housing tract. He believes this inflated sale, based on a so-called “black box” valuation by mortgage giant Fannie Mae or Freddie Mac, has subverted other sales in the tract and is a microcosm of what is causing housing inflation coast to coast.
Based on Crawford’s analysis, the data cancer began with a so-called appraisal waiver by Fannie or Freddie – “appraisal waiver” is code for the twins’ nearly complete use of artificial intelligence and Big Data to assign synthetic values to properties across the country. They have created a self-reinforcing distortion cycle, says Crawford, in which data, once initially distorted, is fed back into a looped system that further subverts lending decisions by the mortgage giants. The twin government-sponsored enterprises together guarantee around 70% of U.S. mortgages. They fully control the market while ostensibly relying on its independent functioning.
Even when a human appraiser goes back and values a property influenced by data cancer, the cancer has already worked its way into the comparable sales. Crawford describes the problem as insidious. The State of Maryland has taken an interest in these activities. Other states may follow. Moreover, in valuing a property in order to “waive” a traditional appraisal, Freddie and Fannie openly violate a key federal consumer protection statute, but more on that in a moment.
The use of quick and inexpensive artificial intelligence to synthesize value has also introduced the likelihood of something computer scientists call “virtual input phenomena” or “spontaneous generation.” This phenomenon, akin to human hallucinations, happens within artificial neural networks." ........
