What Is an Appraisal Review? A Comprehensive Guide to Purpose, Process and Reviewers
In real estate valuation, accuracy and credibility are everything. A single appraisal can influence lending decisions, investment strategies, legal outcomes and property transactions worth millions. This is where appraisal reviews play a critical role. Acting as a safeguard for valuation integrity, appraisal reviews ensure that property appraisals meet professional standards, regulatory requirements and real-world expectations.
This comprehensive guide by Suntel Global explains what an appraisal review is, why it matters, the different types of appraisal reviews, who requests them and who is qualified to perform them.
Understanding Appraisal Reviews in Real Estate
An appraisal review is the process in which one qualified appraiser evaluates the work completed by another appraiser. The purpose is not to criticize the individual, but to assess the quality, accuracy, methodology and compliance of the appraisal report itself.
According to the Uniform Standards of Professional Appraisal Practice (USPAP), an appraisal review involves forming an opinion about the reliability and credibility of another appraiser's work, whether that work consists of a full report, a portion of a report or supporting documentation.
In simpler terms, an appraisal review functions as a professional quality control mechanism—a second set of trained eyes confirming that the valuation process was sound and defensible.
Why Are Appraisal Reviews Necessary?
Many people ask why a second professional opinion is required when an appraisal has already been completed by a licensed expert. The answer lies in the complexity and impact of property valuations.
1. Protecting Market Integrity
Real estate markets rely heavily on trust. Historical financial crises—including the Savings and Loan crisis and the global mortgage collapse—revealed how inaccurate valuations can destabilize entire financial systems. Appraisal reviews were strengthened as a direct response to these lessons.
2. Ensuring Compliance and Consistency
Appraisals must adhere to USPAP standards, lender guidelines and jurisdiction-specific regulations. A review ensures these benchmarks are consistently met.
3. Reducing Financial Risk
For lenders and investors, appraisal reviews act as a risk-management tool. Verifying collateral value helps prevent over-lending and protects stakeholders.
4. Supporting Legal and Tax Matters
In litigation, tax appeals and condemnation cases, appraisal reviews provide credibility—or identify weaknesses—in valuation reports used as evidence.
Who Requests an Appraisal Review?
Appraisal reviews are requested by a wide range of stakeholders across the real estate ecosystem, including:
- Mortgage lenders verifying collateral value before loan approval
- Appraisal Management Companies (AMCs) conducting internal quality checks
- Investors assessing acquisition or portfolio risk
- Attorneys involved in disputes, litigation or eminent domain cases
- Government agencies for regulatory or tax compliance
- Property buyers and sellers seeking a second opinion
- Insurance companies validating insured values
This diversity of users highlights how appraisal reviews support decision-making across financial, legal and regulatory environments.
Appraisal Review vs. Fact-Checking: What's the Difference?
It's important to distinguish between a formal appraisal review and basic fact-checking.
Fact-Checking (Administrative Review)
- Verifies data accuracy (property details, photos, documents)
- Confirms client-specific requirements
- Often performed by non-appraisers
- Does not involve an opinion on valuation credibility
Appraisal Review
- Must be conducted by a certified appraiser
- Evaluates methodology, analysis and conclusions
- Requires a defined client and intended use
- Results in a professional opinion on report quality
While fact-checking ensures completeness, an appraisal review ensures credibility.
Types of Appraisal Reviews
The scope of an appraisal review depends on the client's needs, risk exposure and intended use. Generally, appraisal reviews fall into three main categories.
1. Form Reviews (Administrative-Level Review)
Form reviews are the least intensive type of appraisal review and are often used for routine quality control.
Key Focus Areas:
- Defined scope of work
- Required exhibits and documentation
- Report consistency and clarity
- Basic compliance with standards
These reviews typically do not involve independent market research or a second opinion of value. Government-sponsored enterprises such as Fannie Mae and Freddie Mac commonly use this review type.
2. Desk Reviews (Technical Review)
Desk reviews go deeper than form reviews and require more analytical effort.
What the Reviewer Evaluates:
- Market data and comparable selection
- Valuation methodology
- Calculations and adjustments
- Compliance with USPAP standards
Desk reviews are conducted without a site visit and are frequently used for moderate-risk lending decisions or lower-value transactions.
3. Field Reviews (Comprehensive Review)
Field reviews are the most thorough and time-intensive form of appraisal review.
Reviewer Responsibilities Include:
- Exterior property inspection
- Independent market and neighborhood analysis
- Verification of comparable sales
- Developing an independent value opinion
Field reviews are typically ordered when concerns exist about the original appraisal or when high-value assets are involved. While not a second appraisal, they come very close in depth and reliability.
Appraisal Review Reporting Formats
Just like appraisals, review reports can be delivered in various formats depending on client requirements.
Form-Based Reports
Commonly used in residential lending, standardized forms are widely accepted but must still comply with USPAP.
Narrative Reports
Often used for commercial, legal or non-lending assignments, narrative reviews provide flexibility and detailed analysis.
Hybrid Reports
Combine structured templates with narrative explanations for clarity and efficiency.
Oral Reports
Used primarily in legal settings or expert testimony. Even when delivered orally, the review must be fully developed and supported by a compliant workfile.
What Happens After an Appraisal Review?
Once the review is complete, the reviewer will typically:
- Confirm agreement with the original appraisal or
- Identify deficiencies and recommend corrective action or
- Suggest a more extensive review or a new appraisal altogether
The goal is always to support informed decision-making—not to penalize the original appraiser.
Who Can Perform an Appraisal Review?
Not every appraiser is qualified to perform appraisal reviews.
Key Requirements Include:
- Proper licensure or certification
- Relevant experience (typically 3–5 years minimum)
- Competency in the property type and market
- Equal or higher credential than the original appraiser
In many cases, state appraisal boards may impose additional requirements beyond national standards.
Why Appraisal Reviews Matter to the Industry
Appraisal reviews serve multiple critical functions:
- Provide reliable second opinions
- Strengthen confidence in valuation conclusions
- Support regulatory compliance
- Reduce lending and investment risk
- Enhance credibility in litigation
- Protect the public trust
They are not obstacles—but safeguards.
The Most Important Thing to Remember
Appraisal reviews often feel intimidating, but they should never be taken personally. The review evaluates the report, not the individual appraiser. When viewed correctly, appraisal reviews promote professional growth, collaboration and consistency across the valuation industry.
