A mortgage lender subject to the 2024 AVM rule uses a third-party vendor's AVM for credit decisions on principal dwellings. Who is responsible for ensuring that the vendor's AVM activities comply with nondiscrimination laws?

Correct Answer

B) The lender, which remains responsible for its providers' compliance

The agencies reminded institutions that use third-party providers that they remain responsible for ensuring those providers comply with applicable laws, including nondiscrimination laws. The rule applies to lenders that make credit decisions themselves or through or in cooperation with a third party, so outsourcing the model does not shift the duty to the vendor. The rule creates no agency registration of AVM vendors and does not assign the duty to appraisers.

Answer Options
A
The vendor alone, because the lender did not design or build the model
B
The lender, which remains responsible for its providers' compliance
C
The federal agencies, through registration of approved AVM vendors
D
The appraiser assigned to each loan, who must review the AVM estimate

Why This Is the Correct Answer

Option B is correct because the agencies stated that institutions using third-party providers remain responsible for ensuring those providers comply with applicable laws, including nondiscrimination laws. The rule's requirements apply to lenders that use AVMs directly or through a third party. The lender therefore needs third-party risk management and controls covering the vendor's model.

Why the Other Options Are Wrong

Option A: The vendor alone, because the lender did not design or build the model

Option A places responsibility on the vendor alone because the lender did not build the model. Commenters raised this point, but the agencies kept the duty with the lender and reminded institutions that they remain responsible for their providers.

Option C: The federal agencies, through registration of approved AVM vendors

Option C says the federal agencies take responsibility through registration of approved AVM vendors. The rule contains no vendor registration or approval system; it requires the lender to maintain its own policies, practices, procedures and control systems.

Option D: The appraiser assigned to each loan, who must review the AVM estimate

Option D assigns responsibility to the appraiser on each loan. AVM-based credit decisions may involve no appraiser at all, and the rule places the quality control duty on mortgage originators and secondary market issuers.

Outsource the model, keep responsibility

A lender can buy an AVM from a vendor, but it cannot hand off its legal responsibility for how that AVM performs in its lending.

How to use: Use this phrase when a question asks who is accountable for a vendor-supplied model used in lending decisions.

Exam Tip

When a regulated institution relies on a third party, expect the regulator to hold the institution responsible for the third party's compliance.

Common Mistakes to Avoid

  • -Assuming the model developer bears the lender's regulatory duty
  • -Believing regulators certify AVM vendors under the rule

Concept Deep Dive

Analysis

The question tests where accountability sits when a lender relies on an outside AVM. The rule covers lenders that make credit decisions themselves or through or in cooperation with a third party, and the agencies stated that institutions remain responsible for third-party compliance. The candidate must reject the intuitive idea that the model's builder carries the legal duty.

Background Knowledge

Bank regulators consistently hold institutions accountable for activities they outsource. In the AVM rule this principle applies to the nondiscrimination factor and to the other quality control factors, supported by existing guidance on third-party risk and fair lending.

Real-World Application

A lender's fair lending team asks its AVM vendor for documentation on data sources and testing across neighborhoods. When the vendor's answers are thin, the lender adds its own outcome testing before continuing to use the model.
