| Quick Answer: A desk review is an appraisal review performed from the office, examining an existing report’s data, comparables, and conclusions without visiting the property. A field review adds an on-site component—the reviewer inspects the subject and often the comparables. Field reviews are more thorough and costly; desk reviews are faster and used for lower-risk quality checks. Both are reviews of an existing report, distinct from a new origination appraisal. |
What is a desk review?
A desk review is an office-based evaluation of an existing appraisal report—its data, comparable selection, adjustments, and conclusions—performed without a site visit. Lenders order it when they want a qualified second set of eyes on the report’s logic without the cost of fieldwork, which makes it well suited to routine quality control or a specific underwriting question.
Because it produces documented valuation work product, it falls under the CFPB’s rule on providing appraisals and valuations (§ 1002.14) (CFPB, Regulation B). A desk review can confirm that comps are appropriate and adjustments are supported, or it can flag issues that warrant a closer look—but it does so from the data already in the file rather than from a fresh inspection.
What is a field review?
A field review is a review that includes an on-site inspection of the subject property and frequently the comparable sales, going beyond what the original report shows on paper. It is warranted when a file is high-value, complex, or the original report raises concerns that only an on-site look can resolve.
The reviewer evaluates another appraiser’s work against professional standards rather than originating a new value, but the physical inspection lets them verify condition, location influences, and comparable characteristics directly. That added rigor is why a field review costs more and takes longer—and why lenders reserve it for the files where the extra certainty is worth the expense.
How do desk and field reviews differ from a desktop appraisal?
A desk review and a field review are both reviews of an existing appraisal, whereas a desktop appraisal is an original valuation developed without a physical inspection. The words sound similar, but the purpose is completely different: a review checks someone else’s work, while a desktop appraisal produces a fresh opinion of value.
Fannie Mae’s desktop appraisal materials (Fannie Mae, 2026) describe that original product, which is easy to confuse with a “desk” review precisely because both happen from the office. Keeping the terms straight matters in conversations with underwriting and investors, because ordering the wrong one wastes time and money.
When should a lender choose each review type?
Choose a desk review for routine quality control and lower-risk files, and a field review for high-value, complex, or flagged files where an on-site inspection is needed. The decision is a balance of risk and cost: a desk review is fast and inexpensive but limited to the data in the file, while a field review is thorough but slower and costlier.
Many lenders use desk reviews as a broad quality-control screen and escalate to a field review only when the desk review or the original report surfaces something that cannot be resolved on paper. The valuation-independence requirement in the CFPB’s § 1026.42 (CFPB, Regulation Z) applies to reviewers as well, so a review assesses quality without pressuring the original appraiser’s value. Property type and loan risk also factor into the choice: a high-value or unusual property, or a loan headed for a stricter investor, often justifies the added cost of a field review even when the file looks clean on paper, simply because the downside of an undetected error is larger.
How do reviews fit into a quality-control program?
Reviews are one layer in a broader quality-control program, sitting alongside automated checks and experienced human oversight to catch problems before a loan funds. A strong AMC pairs technology-driven screening with reviewer expertise to identify unsupported comps, math errors, missing disclosures, and bias-language concerns early.
R3 AMC coordinates both desk and field reviews as part of its quality-control toolkit, and its broader QC process—summarized in its FAQ—layers AI-assisted review through ValueTest.ai, compliance checks against USPAP and agency guidelines, and human review by experienced staff appraisers. The goal is to surface issues before delivery rather than discovering them in a post-close audit.
What should a lender expect from an AMC’s review services?
A lender should expect clear criteria for when each review type is used, qualified appraiser-reviewers, documented findings, and full independence from the original valuation. Ask how the AMC selects reviewers, how it documents conclusions, and how it escalates from desk to field review when warranted. R3 AMC provides review services nationwide as part of a structured quality-control approach designed to protect loan quality and reduce repurchase risk.
It also helps to understand what a review is not. A review is not a tool to pressure an original appraiser into changing a value, and it is not a negotiation; under appraiser-independence rules, a reviewer assesses whether the work meets professional standards and documents that opinion, full stop. If a review identifies a genuine deficiency, the appropriate path is a documented reconsideration or, where warranted, a new appraisal—not informal pressure on the original appraiser. A disciplined AMC keeps that line bright, which is exactly what protects the lender if the file is later examined or the loan is sold into the secondary market.
