Yes, you can challenge a home appraisal through a Reconsideration of Value (ROV) process. You gather comparable sales evidence supporting a higher value, submit it through your lender to the appraiser, and they review it within 5-10 days. It works best when you can point to factual errors or recent sales the appraiser missed.
The Appraisal Reconsideration Process
If you believe an appraisal is wrong, you can request a "Reconsideration of Value" (ROV).
Here's how it works:
- Gather Evidence: Find comparable sales that support higher value
- Submit Request: Send documentation to the appraiser (usually through your lender or the appraisal management company)
- Appraiser Reviews: The appraiser looks at your evidence
- Decision: Appraiser either increases the value, keeps it the same, or explains their analysis
The whole process takes 5-10 days.
What Actually Works in Appraisal Challenges
I'm on the appraiser side of this equation, so let me be honest: Most challenges don't work.
Here's why: The appraiser already researched comparable sales. They already found the comparable homes you're going to cite.
If you find a recent sale that supports higher value, the appraiser likely already found it. If they didn't include it, they have a reason (different neighborhood, different property type, different condition).
Challenges work when:
The Appraiser Made a Factual Error
- Recorded wrong square footage
- Missed a major recent comparable sale
- Misidentified the neighborhood
- Got the property condition wrong
You Have New Data
- A comparable home just sold (after the appraisal) that's substantially higher
- A major neighborhood improvement happened
- Your property had an inaccuracy in the appraisal (that you can prove)
Legitimate Disagreement on Adjustment
- You think a comparable sale should have been adjusted differently
- You have market data supporting different adjustment amounts
This is rare and hard to prove.
What Doesn't Work
Challenges don't work when:
- You just don't like the appraisal
- You think your home "feels" worth more
- You're emotional about the low value
- You simply disagree with the appraiser's professional judgment
Appraisals aren't subjective. They're based on comparable sales data. If the data supports the low value, the appraisal is defensible.
Real Example: When a Challenge Worked
Offer price: $500,000 Initial appraisal: $475,000 (based on comparables at $460,000-$475,000)
You find a comparable home that:
- Sold 3 weeks ago
- 2 blocks away
- Nearly identical property
- Sold for $495,000
You submit this new comparable to the appraiser.
The appraiser looks at it and says: "I didn't have this sale when I wrote my appraisal. This new data supports higher value."
Appraisal is reconsidered upward to $485,000 or $490,000.
This worked because: You had legitimate new data the appraiser didn't have.
Real Example: When a Challenge Failed
Offer price: $500,000 Appraisal: $475,000 (comparable homes sold at $460,000-$475,000 range)
You argue: "My home has a better view than the comparables. It should be worth more."
Appraiser responds: "I analyzed comparable homes with views vs. homes without views. The view premium in this market is $5,000-$10,000. I already accounted for your superior location."
This didn't work because: The appraiser already considered your view advantage and had comparable sales supporting their adjustment.
When You Should Challenge
Challenge the appraisal if:
- You have new comparable sales (after the appraisal date)
- You found a factual error in the appraisal
- You have legitimate market data the appraiser missed
- You genuinely believe the comparable sales are being mis-adjusted
Don't challenge just because you're unhappy with the value.
The Strategic Question
Before challenging, ask yourself: Is the appraisal wrong, or was my offer price wrong?
If comparable homes are selling for $475,000, and yours is similar, the appraisal of $475,000 is right.
Challenging won't change that. The market says $475,000.
Accept it. Renegotiate with the seller. Move on.
Success Rate
Honest answer: About 15% of ROV requests result in upward value changes.
Most appraisals stand because they're based on solid comparable sales analysis.
Appraisers don't make wild guesses. We use market data. If the data says $475,000, that's what the appraisal reflects.
What You Can Do Instead
If the appraisal is legitimately lower than market (which is rare), here are better moves:
- Renegotiate with seller — Easiest path. Seller accepts lower price.
- Walk away — Use appraisal contingency. Find a correctly-priced home.
- Bridge the gap — Pay the difference if you truly believe the home is worth more.
Challenging works sometimes, but it's not the primary solution.
The Professional Perspective
As an appraiser, I welcome legitimate questions about my valuation. If I made an error, I want to know. If there's new data, I want to see it.
But I also stand by my work. If my appraisal is based on solid comparable sales analysis, I won't change it just because a buyer doesn't like the number.
The appraisal reflects the market. The market is what it is.
Challenge when you have legitimate evidence. Otherwise, accept the appraisal and adjust your strategy accordingly.
That's the realistic approach.
