What Is the Loan-to-Value Ratio?
The loan-to-value ratio (LTV) measures your outstanding mortgage balance as a percentage of your home's current market value. It is the primary metric lenders use to assess the risk of a mortgage — both when you originally buy a home and when you apply to refinance.
A low LTV means you own a large share of your home outright, which reduces the lender's risk. A high LTV means you owe close to (or more than) what the home is worth, which increases risk and triggers additional costs like private mortgage insurance.
Your LTV changes over time as you make mortgage payments (reducing the balance) and as your home's market value rises or falls. When home values increase, your LTV improves even without making extra payments — which is why homeowners who bought in appreciating markets often refinance years later to remove PMI or access equity.
LTV Thresholds and What They Mean
Lenders don't treat all LTV ratios the same. There are key breakpoints that trigger different requirements and pricing:
| LTV Range | PMI Required? | Rate Impact | Cash-Out Available? |
|---|---|---|---|
| ≤ 60% | No | Best available rates | Yes (up to 80% LTV) |
| 60.01% – 80% | No | Excellent — minor LLPAs | Yes (up to 80% LTV) |
| 80.01% – 95% | Yes | Moderate LLPAs apply | No (above 80%) |
| 95.01% – 97% | Yes | Significant LLPAs | No |
| > 97% | Yes | Limited options | No |
How LTV Affects Your Refinance
Rate pricing (LLPAs)
Fannie Mae and Freddie Mac charge loan-level price adjustments (LLPAs) based on LTV and credit score. These adjustments are baked into your interest rate by the lender. As LTV rises above 80%, LLPAs increase, and your rate rises with them. A move from 85% to 79% LTV can reduce your rate by 0.125%–0.375%.
PMI removal
If you're currently paying PMI, refinancing once your LTV reaches 80% eliminates it entirely on a new conventional loan. If you've already paid down to 80%, you can request PMI cancellation without refinancing (Homeowners Protection Act). Refinancing can make sense specifically to remove PMI if your home has appreciated significantly.
Cash-out eligibility
Cash-out refinancing is only available when the new loan doesn't exceed 80% LTV (for conventional loans). If your current LTV is already above 80%, you cannot take cash out until your home value increases or your balance decreases enough to create that equity cushion.
Worked Example
At 72.5% LTV: no PMI, qualifies for best rate tiers, and has $80,000 in available cash-out equity (up to 80% LTV = $320,000 new loan limit, minus $290,000 balance = $30,000 available). This borrower is in a strong refinance position.
How to Improve Your LTV Before Refinancing
- Make extra principal payments — even small additional amounts reduce your balance over time.
- Wait for appreciation — rising home values in your market will improve your LTV passively.
- Get a new appraisal — if your home has improved or the market has risen, a current appraisal may show a higher value than your lender's records reflect.
- Pay a lump sum — if you're close to a key threshold (e.g., 82% LTV), a one-time payment to push below 80% can eliminate PMI and meaningfully improve your rate.
Frequently Asked Questions
What LTV do I need to refinance?
Most conventional lenders accept up to 97% LTV for a rate-and-term refinance. For the best rates, target 80% or below. FHA allows up to 97.75% LTV. VA and USDA loans may allow 100% LTV refinances for eligible borrowers.
What is a good LTV for a mortgage?
80% or below is the target for most homeowners — it eliminates PMI and unlocks the best rate tiers. Below 60% earns the absolute lowest available rates. Above 95% LTV, your refinance options narrow considerably.
How does LTV affect my interest rate?
Lenders apply loan-level price adjustments (LLPAs) that increase with LTV. Moving from 85% to 79% LTV can reduce your rate by 0.125%–0.375%, which over a 30-year loan translates to tens of thousands of dollars. Even crossing a single 5% LTV band can have a meaningful rate impact.
Can I refinance if my LTV is over 80%?
Yes — but you'll pay PMI on a conventional loan, and cash-out is unavailable. FHA refinances work above 80%. If your LTV exceeds 100%, check current FHFA programs for high-LTV refinance options.
