A home appraisal that comes in lower than expected can derail a deal or leave you scrambling to cover the difference. Getting a second appraisal—also called a secondary or follow-up appraisal—is a legitimate move that protects your investment and can overturn a disappointing valuation. Here's what you need to know about when and why homebuyers request them.
Why Appraisals Matter in Home Transactions
Your appraisal determines how much a lender will finance. If the property appraises for less than the agreed purchase price, you either make up the difference in cash, renegotiate the price, or walk away. Most lenders base their loan-to-value (LTV) ratio on the appraisal, not your contract price, which is why a low appraisal can create real financial consequences.
An appraisal gap of $10,000–$50,000 isn't uncommon in competitive markets, especially when bidding wars drive purchase prices above market fundamentals. That's when a second opinion becomes strategically important.
When Homebuyers Request Second Appraisals
Low appraisal relative to purchase price
If the appraiser valued the home $20,000 or more below your offer, a second appraisal is worth the cost. Appraisers sometimes miss comparable sales, overlook recent renovations, or undervalue desirable neighborhood features. A fresh appraisal from another licensed professional can validate the home's true market value.
Questionable comparable sales selection
Review the comps the appraiser used. If they pulled properties that sold 18 months ago, are in notably different neighborhoods, or had non-arm's-length transactions, push back. A second appraiser may have access to better, more recent comparables that justify a higher valuation.
Significant recent upgrades not reflected
Did you negotiate for a kitchen remodel, new roof, or HVAC system as part of the deal? Some appraisers factor these in inconsistently. A second appraisal gives the appraiser a fresh opportunity to properly document and value those improvements.
Unusual market conditions
In areas with limited inventory or rapid price appreciation, one appraiser's conservative estimate might not capture the true market. A second appraisal in a heated market can reflect current buyer demand more accurately.
The Cost and Timeline
Expect to pay $300–$600 for a residential appraisal, depending on your property's complexity and location. Rural properties, large estates, or homes with unique features (pools, guest houses, vineyards) may cost $700–$1,000. Most appraisals take 7–14 days from order to final report—a timeline you need to factor into your closing schedule.
Order a second appraisal quickly if the first one disappoints. You typically have 3–5 days after receiving a low appraisal to contest it with your lender, and ordering a second appraisal within that window strengthens your negotiating position.
Steps to Request a Second Appraisal
- Contact your lender or loan officer first. Some lenders have a formal review process where you can challenge the appraisal in writing, providing evidence of why the valuation seems off. This is sometimes free or less expensive than ordering an entirely new appraisal.
- Request an appraisal review or desk review. Your lender may send the report back to the same appraiser or a supervisor to reconsider the findings. This costs $100–$200 and takes 2–5 days.
- Order a full second appraisal if the review doesn't move the needle. Use a different, independently licensed appraiser to avoid bias. Ensure they have local expertise and understand your specific neighborhood.
- Provide clear documentation to the second appraiser: photos of recent upgrades, receipts for renovations, comparable sales data you've researched, and any unique property features the first appraisal overlooked.
What Happens If the Second Appraisal Is Higher
If the second appraisal comes in higher, share both reports with your lender. Most lenders will use the higher valuation for loan approval purposes, particularly if the second appraiser is equally credible. Some lenders average the two appraisals. Document everything in writing to your loan officer so there's a clear record.
If both appraisals are low, you'll need to decide whether to increase your down payment, renegotiate the purchase price, or reconsider the deal. Platforms like Mercoly help you find and compare trusted residential appraisal providers in one place, making it easier to get a second opinion quickly.
Frequently Asked Questions
Q: Can I dispute an appraisal without ordering a second one? Yes—request a reconsideration of value (ROV) with your lender first. It's free or low-cost and sometimes results in a revised valuation without a full second appraisal.
Q: Will my lender accept a second appraisal from any licensed appraiser? Your lender must approve the appraiser and will verify they meet state licensing requirements and have no conflicts of interest. Check with your loan officer about their approved appraiser network beforehand.
Q: How much can appraisals differ between professionals? Differences of 3–5% are normal; anything beyond 10% suggests real discrepancies in methodology or comparable sales selection and warrants investigation.
