The Rule That Already Applies
6 min read
On 1 October 2025, quality control standards for automated valuation models took effect across six federal agencies. The rule has been in force for ten months and almost nobody in residential real estate discusses it.
The final rule was published on 7 August 2024 at 89 FR 64538, adopted jointly by the Office of the Comptroller of the Currency, the Federal Reserve, the FDIC, the National Credit Union Administration, the Consumer Financial Protection Bureau and the Federal Housing Finance Agency. It sits under Section 1473(q) of Dodd-Frank, which added Section 1125 to FIRREA, and is codified across seven parts of the Code of Federal Regulations.
Five standards, and one of them is not what you would expect
Institutions using an automated valuation model in a covered credit decision or securitization determination have to maintain policies and practices designed to do five things.
Ensure a high level of confidence in the estimate. Protect against the manipulation of data. Avoid conflicts of interest. Require random sample testing and reviews. And comply with applicable nondiscrimination laws.
The first four read like sensible model governance and would surprise nobody who has built or bought one of these systems. The fifth is what makes this different from the guidance it replaced. It puts fair lending obligations into the quality control standard for the model itself, rather than treating the model as neutral infrastructure somebody else is responsible for using properly.
What preceded it was guidance rather than a rule. Appendix B of the Interagency Appraisal and Evaluation Guidelines has addressed AVM validation since 2010. The difference is that guidance describes what examiners expect and a rule describes what institutions must have.
What it covers
The scope is narrower than the attention it deserves. The rule reaches mortgage originators and secondary market issuers using AVMs to determine the value of a consumer's principal dwelling, in connection with a credit decision or a securitization determination. That is the boundary. A lender running a model to decide whether to lend is covered. So is an issuer using one to decide what goes into a pool.
Nothing here prohibits anything. It requires the institution to have policies ensuring the five standards are met, and to be able to show them.
Where it stops, which is the part worth sitting with
An estimate produced for a consumer to read, rather than for an institution to lend against, is outside this.
The portal figure a homeowner has been watching for three weeks is not a covered use. Neither is the number a seller quotes in a listing appointment because they saw it on a screen in June. The same class of technology, frequently trained on the same public records and the same transaction data, is held to five federal standards in one context and to none in the other.
And the uncovered context is the one that arrives first. By the time a lender's covered model runs, a price expectation has already been formed, negotiated around, and in many cases written into a listing agreement. The regulated number validates a transaction. The unregulated one shaped it.
That is not a criticism of the rule. Its authority runs to institutions the six agencies supervise, and consumer-facing estimates are not that. It is an observation about which number does more work in a residential transaction.
A confidence requirement with no failure state
One detail deserves more attention than it has had. The first standard requires policies designed to ensure a high level of confidence in the estimate. It does not define what an institution does when that confidence is not available. There is no described state in which the model declines, returns nothing, or flags that the evidence will not support an answer.
That is the same gap that exists in commercial valuation products, which this shelf has covered from the product side. Every tool returns a number for any input, and confidence is reported as a label describing the output rather than a decision about whether the output should exist. The federal rule inherits the same shape. It asks for confidence and is silent on absence.
In practice that pushes the question into each institution's model risk management, which is probably where it belongs and also where nobody outside can see it.
What does the AVM quality control rule require?
Policies and practices reasonably designed to ensure a high level of confidence in the estimate, protect against data manipulation, avoid conflicts of interest, require random sample testing and reviews, and comply with applicable nondiscrimination laws. It applies to institutions using AVMs in credit decisions or securitization determinations for a consumer's principal dwelling, and it took effect on 1 October 2025.
Does the AVM rule apply to a portal's home value estimate?
No. The rule reaches covered uses by mortgage originators and secondary market issuers. An estimate published for a consumer to read, where no covered credit decision or securitization determination is being made against it, sits outside the scope. The same technology can therefore be regulated in one setting and unregulated in another.
When did the AVM quality control rule take effect?
1 October 2025. The final rule was published on 7 August 2024 at 89 FR 64538 and was adopted jointly by six agencies. Before it, the operative position was supervisory guidance dating to 2010 under Appendix B of the Interagency Appraisal and Evaluation Guidelines.
What an operator should take from it
Two things, and neither is a compliance task.
The first is that the criteria this shelf and others have argued for, when judging an automated valuation tool, are close to what six federal agencies wrote down. Testing, conflicts, data integrity, nondiscrimination. If those are the standards a regulator applies to a model deciding a loan, they are a reasonable floor for a model an office asks its agents to rely on, whether or not anyone is required to meet them.
The second is that the gap between covered and uncovered is where an agent's week is spent. Every seller who arrives with a number arrived with an uncovered one. Nothing about that is improper. It just means that the figure carrying the least oversight is the figure doing the most work in the conversation, and knowing which is which is worth more than knowing the rule.
For the avoidance of doubt, nothing CMAflow produces is a covered AVM under this rule. We are not a mortgage originator or a secondary market issuer, and no credit decision runs against our output. So the standards we hold ourselves to are ours rather than anyone's, which is a weaker guarantee than a regulation and should be read that way.
This is analysis rather than legal or compliance advice, and any institution's obligations are a matter for its own counsel.
