Bias against minorities has been “proven” against property value message measurers – at least once.  It has also been “proven” that the undervaluation is as much as $500, on average.  Something must be done!  Let’s blame the appraisers!  They keep on “determining” values too low!

Does the flurry of blame-placing help resolve the problem?  But something must be done!  Many are involved.  Everyone, regulators, legislators, lenders, agents, and others vested in loan-making, must at least appear to be working at this glaring problem of “obvious” appraiser bias.  They need to take action, some action.

And the originators of the bias-awareness project also turn out right.  Minorities do possess less property assets (from past generational wealth).  And appraisers are an easy target.  They are the front-door face of the value of my home.  My eyes are on the back of that appraiser walking away from my home.  But if we want to go beyond placing blame . . .   If we genuinely want to find some solution, some fairness . . .  can we look other places?

Does the problem reside in:

  • Personal appraiser bias;
  • Appraisal ‘Bias: Personal or Analytic?;
  • Lender pressure on appraisers;
  • AMC pressure on appraisers;
  • Data collection bias;
  • Agent listing price bias;
  • Agent expectation bias;
  • Buyer/seller personal bias;
  • Buyer/seller prudence/knowledgeability;
  • Buyer/seller motivational mindset;
  • External stimulus.

Or could it be a ‘continuation’ of prior prejudice, policy, or prohibitive redlining?

No problem.  It must be the appraiser.  It must be.  At worst it must be systemic in the very appraisal process itself.  Is it possible that the vintage appraisal ‘process’ is outdated, and vulnerable to bias?

In prior Analogue Blog issues, we have asked whether racial bias might be aggravated by what appraisers are required to do:

  1. Appraisers must do as their peers do. Believability, (not justice), is the standard (per USPAP);
  2. Appraisers must do what their clients expect (per USPAP);
  3. Appraisers must report the market, not set value.

Appraisers are the carriers of the message of any real or imagined racial bias. We could kill the messenger.  Or we can revise the appraisal process to reflect modern analytics, modern data selection, and interface to the expert brain.  Can we provide a context from which the issue of bias (in all its forms) is clearly presented and visible?

Only by integrating the potential of data science with appraiser knowledge and market familiarity can we measure and reform what has gone wrong.  “Pick comps and make adjustments” has to be put to history.  We have the data.  We have the tools.  We can do better.  We can protect minorities as well as the economic public trust.

Good public policy comes from good measurement of the problem.  It will not come from more browbeating of the carrier of the message – the appraiser.
