Case Study: Challenging an Appraisal with Better Comps

13 minPRO
5/6

Key Takeaways

  • A successful ROV requires superior comps and identification of specific errors in the original appraisal.
  • Focus on location, recency, and adjustment magnitude when arguing comp superiority.
  • Verify all comp data against county records to identify undisclosed concessions or errors.
  • Present the ROV professionally with data and documentation, not emotional arguments.

When an appraisal comes in below the contract price, the buyer faces a critical decision: renegotiate, bring additional cash, or challenge the appraisal with a Reconsideration of Value (ROV). This case study walks through a successful appraisal challenge where the buyer provided superior comparable sales and demonstrated errors in the original appraisal.

Scenario 1
Basic

Case Setup: $30K Appraisal Gap

The buyer has a purchase contract at $310,000 for a 4BR/2.5BA colonial in the Oakview subdivision. The appraisal comes in at $280,000—a $30,000 gap. At 80% LTV, the appraisal limits the loan to $224,000 instead of $248,000, requiring an additional $24,000 in cash at closing (the $30K gap minus $6K already planned above the original down payment). The buyer believes the appraisal is understated because the appraiser used two comps from an adjacent, less desirable neighborhood and made an unusually large negative adjustment for the subject's recently renovated kitchen.

Financial Impact
Contract: $310,000 | Appraisal: $280,000 | Gap: $30,000 Original loan (80% of $310K): $248,000 Revised loan (80% of $280K): $224,000 Additional cash required: $24,000
Scenario 2
Moderate

Preparing the ROV Package

A successful ROV requires more than just submitting higher-priced comps—it requires demonstrating specifically why the original appraisal's comps or adjustments are inferior to the alternatives. Step 1: Identify superior comps. The buyer found two comps the appraiser missed: a 4BR/2.5BA colonial in Oakview that sold for $305,000 two months ago (same subdivision, closer physical match), and a 4BR/3BA colonial one block from the subject that sold for $318,000 with a $6,000 downward bathroom adjustment = $312,000. Step 2: Document why these comps are superior. Both are in the same subdivision (the appraiser's comps were in adjacent, lower-value neighborhoods). Both are more recent (sold within 2 months vs. the appraiser's 8-month-old comps). Both are closer physical matches requiring fewer adjustments. Step 3: Identify errors in the original appraisal. The appraiser applied a -$15,000 kitchen adjustment to the subject, penalizing it for having a superior kitchen. Standard practice is to adjust the comp upward, not the subject downward. Additionally, one of the appraiser's comps had an unrecorded $8,000 seller concession that effectively overstated its sale price.

Scenario 3
Complex

Submitting the ROV and Outcome

The ROV package was submitted to the lender with: (1) a cover letter summarizing the three specific issues (inferior comp locations, kitchen adjustment error, undisclosed concession), (2) full MLS data sheets for the two alternative comps, (3) county deed records verifying sale prices, (4) photographs showing the subject's renovated kitchen that the appraiser penalized, and (5) a simple adjustment grid showing the alternative comps' adjusted values of $305,000 and $312,000. The lender forwarded the ROV to the appraiser, who revised the appraisal to $305,000. The revised appraisal still fell $5,000 short of the $310,000 contract, but the gap was manageable: the buyer needed only $4,000 in additional cash rather than $24,000. The seller agreed to reduce the price by $3,000 to $307,000, and the deal closed successfully.

ROV Best Practices
Focus on three elements: (1) Superior comps with documented reasons why they are better. (2) Specific errors in the original appraisal (factual or methodological). (3) Professional presentation with data, not emotion. Never attack the appraiser personally—focus on the data.

Watch Out For

Selecting comparable properties based on price proximity to a desired value rather than true similarity.

Circular reasoning confirms a predetermined conclusion instead of independently estimating market value.

Fix: Select comps based on physical and locational similarity, not on how close their prices are to your target.

Failing to adjust for differences in transaction conditions between comparable sales.

Non-arm's-length sales, seller concessions, and financing terms can distort the comp set by 5-15%.

Fix: Verify transaction type and terms for all comps and make appropriate adjustments.
