A home appraisal directly affects your Loan-to-Value (LTV) ratio—calculated using the formula (Loan Amount ÷ Appraised Value) × 100—which influences loan approval, interest rates, and mortgage insurance. If the appraisal is lower than expected, your LTV rises, potentially resulting in worse terms or denial. formula used to calculate Loan-to-Value ratio Managing appraisals smartly can protect your financing by keeping your LTV within lender-approved limits and helping you secure better mortgage options.
What Is Loan-to-Value (LTV) Ratio?
The Loan-to-Value ratio is a simple but powerful number that compares the amount you’re borrowing to the appraised value of the home. It helps lenders assess their risk on a mortgage loan.

LTV Ratio = (Loan Amount ÷ Appraised Value of the Property) × 100
Example:
- Loan amount: $280,000
- Appraised value: $350,000
- LTV: ($280,000 ÷ $350,000) × 100 = 80%
A lower LTV typically means less risk for the lender and better loan terms for the borrower. A higher LTV may result in higher interest rates, mortgage insurance, or even loan denial.
Why Home Appraisals Are Critical to LTV
While buyers often focus on the purchase price, lenders care more about the appraised value. That’s because they base the LTV ratio on what the home is actually worth, not necessarily what you’re willing to pay.
What Happens If the Appraisal Is Lower Than Expected?
Let’s say:
- You agree to buy a home for $400,000
- Your lender agrees to finance 90% of that, or $360,000
- But the appraisal comes in at $380,000
Now, the lender recalculates LTV:
- New LTV = $360,000 ÷ $380,000 × 100 = 94.7%
🚩 Problem: You were approved for a 90% LTV loan, but now you’re at nearly 95%. That might mean:
- A higher interest rate
- More mortgage insurance
- A larger required down payment
- Or your loan could be denied unless you adjust
Low Appraisal Scenarios and How They Affect Buyers
Scenario 1: Appraisal Below Purchase Price
| Purchase Price | Appraised Value | Loan Requested | Resulting LTV |
| $400,000 | $370,000 | $360,000 | 97.3% |
👉 Consequences:
- You now need to pay more out of pocket to meet the LTV requirements
- Or renegotiate the sales price with the seller
- Or risk losing the home if you can’t cover the difference
Scenario 2: Appraisal Higher Than Purchase Price
| Purchase Price | Appraised Value | Loan Requested | Resulting LTV |
| $400,000 | $420,000 | $360,000 | 85.7% |
Benefits:
- Lower LTV could improve your loan terms
- You may avoid mortgage insurance (PMI)
- More equity from day one
LTV Benchmarks Lenders Use
Lenders typically assess LTV in tiers. Here are common thresholds and what they mean:
| LTV Ratio | Impact on Mortgage |
| ≤ 80% | Best interest rates, no PMI required |
| 80.01% – 90% | Higher rates, PMI required |
| 90.01% – 97% | Restricted loan options, higher PMI |
| > 97% | Rare loan programs, higher default risk |
🏦lenders cap LTV at 97%. Government-backed loans like FHA and VA may allow more flexibility.

Understanding the Appraisal Process
A home appraisal is conducted by a licensed, third-party professional hired by the lender. The appraiser evaluates:
- Recent comparable sales (“comps”)
- Market conditions
- Property condition and improvements
- Lot size and location
Typically, this process takes a few days and is required for mortgage underwriting.
What to Do If Your Appraisal Comes In Low
If your appraisal is lower than expected, don’t panic. Here are steps you can take:
1. Review the Appraisal Report
Check for:
- Incorrect property details
- Missing or outdated comps
- Overlooked upgrades or renovations
2. Request a Reconsideration of Value (ROV)
You or your agent can submit new comparables or challenge errors to the lender.
3. Renegotiate the Purchase Price
If the seller agrees, this lowers your loan amount and adjusts your LTV.
4. Make a Larger Down Payment
Cover the difference between the loan amount and appraised value with cash to keep your LTV in check.
5. Switch Lenders
In rare cases, you may order a new appraisal through a different lender with their own appraisal management company (AMC).
