How AVMs Affect Home Appraisals
Automated Valuation Models (AVMs) are commonly used during the initial stages of home loan applications or refinancing to give lenders a general idea of the property’s worth.
What Is An AVM?
Automated Valuation Models (AVMs) are used by banks and financial institutions to quickly estimate a property’s value through algorithms that analyze large datasets. These models pull information from public property records, recent sales data, tax assessments, and neighborhood trends to generate an estimated value for a home.
How AVMs Affect Your Appraisal
In some cases, the AVM is used as the property value, skipping the traditional home appraiser who comes to the property to view, assess, measure, photograph and determine value based on physical inspection.
Speed and Efficiency
AVMs are fast and cost-effective because they generate property valuations instantly without needing a physical inspection. This can be helpful for lenders when they want a quick assessment of whether a property’s value supports a loan amount, especially for lower-risk transactions or when time is a factor.
Final Appraisal Requirement
Even if an AVM is used early in the loan process, a traditional appraisal is often still required to validate the property’s value, especially for high-risk loans, unique properties, or government-backed loans (FHA, VA, etc.). This ensures that the valuation is fair and accounts for all relevant factors, including those that an AVM might overlook.
Potential Pitfalls Of An AVM
While AVMs provide a quick, computer-generated valuation, they can sometimes lack the detailed, nuanced analysis that a traditional appraisal offers.
Limited Accuracy
While AVMs can be useful, they aren’t always as accurate as a traditional appraisal because they rely solely on data and algorithms. They don’t account for the property's condition, recent renovations, or other unique factors that may impact value. For example, a home that has been newly renovated may be undervalued by an AVM if the recent upgrades haven’t been reflected in the public records.
Lack of Human Judgment
An AVM lacks the professional judgment and expertise of a licensed appraiser, who can assess subjective factors such as the home’s condition, the quality of construction, and the neighborhood’s character. For properties that are unique, in a fluctuating market, or in rural areas with fewer comparable sales, AVMs may provide an inaccurate value.
Potential for Over-Reliance
Some lenders may initially rely on AVMs to make decisions, but this can be problematic if the model fails to capture important details. For higher-value loans or complex properties, lenders typically require a traditional appraisal in addition to an AVM to ensure they have an accurate valuation.
New Quality Control For AVMs
Federal agencies have recently released a final rule implementing new minimum quality control standards for automated valuation models (AVMs) used by banks.
Under the final rule, the OCC will require banks that use AVMs in certain credit decisions or securitization determinations to adopt policies, practices, procedures, and control systems to ensure that AVMs adhere to quality control standards designed to:
- Ensure a high level of confidence in the estimates produced by AVMs
- Protect against the manipulation of data
- Seek to avoid conflicts of interest
- Require random sample testing and reviews
- Promote compliance with applicable nondiscrimination laws
While AVMs provide banks with quick, preliminary valuations, they can lack the precision of a full appraisal. For most transactions, particularly those involving significant loans or unique properties, a traditional appraisal is necessary to ensure that the property's value is accurate and reflects all factors that could influence the market value.
