Quick overview
Loan-to-Value (LTV) is a simple ratio with big consequences for homebuyers and homeowners. It tells lenders how much of the property’s value is being financed and how much equity the borrower already owns. Lenders use LTV alongside credit score, debt-to-income ratio, and property type to set rates, require mortgage insurance, and decide loan eligibility.
How LTV is calculated
LTV = (Loan amount ÷ Appraised value) × 100
- Example (purchase): A home appraises at $300,000 and you borrow $240,000. LTV = (240,000 ÷ 300,000) × 100 = 80%.
- Example (refinance): If your mortgage balance is $200,000 and an appraisal values your house at $250,000, your refinance LTV = (200,000 ÷ 250,000) × 100 = 80%.
Note: For purchase loans lenders commonly use the lower of the appraised value or sales price when calculating LTV. For refinances, they rely on a current appraisal or automated valuation depending on the program.

Why LTV affects mortgage costs and approval
- Interest rates: Higher LTVs mean greater risk for lenders, which commonly translates into higher interest rates or fewer product choices.
- Mortgage insurance: Conventional loans typically avoid Private Mortgage Insurance (PMI) once LTV is 80% or lower; FHA loans require mortgage insurance for most LTVs (see FHA rules), while VA loans offer loan guarantees that often allow 100% financing for eligible veterans.
- Underwriting access: Some loan programs set absolute LTV caps (e.g., certain conforming limits for cash-out refinances).
- Loan-to-value and home price swings: LTV moves with property value. If home prices fall, a previously low LTV can become high — increasing refinance difficulty and raising default risk.
Authoritative context: see the CFPB explainer on LTV and mortgage insurance and HUD/FHA program rules.
Typical program LTV thresholds (general guidance)
- Conventional (to avoid PMI): ≤80% LTV. Higher LTVs may be available but usually with PMI and stricter terms. (CFPB)
- FHA purchase: up to about 96.5% LTV (3.5% minimum down payment) for standard mortgage insurance scenarios. (HUD/FHA)
- VA loans: commonly allow 100% financing for eligible veterans (0% down), though residual income and entitlement rules still apply. (U.S. Department of Veterans Affairs)
These thresholds are program-specific and can change with lender overlays or regulatory updates.
Private Mortgage Insurance (PMI) vs FHA/VA mortgage insurance
- Conventional loans with LTV above 80% typically require PMI. PMI reduces lender loss in case of default and adds a monthly or upfront cost for borrowers. The cost depends on LTV, credit score, and loan term.
- FHA loans carry an upfront mortgage insurance premium (UFMIP) and an annual mortgage insurance premium (MIP) regardless of LTV in many cases; the exact treatment depends on loan age and LTV at origination. (HUD/FHA)
- VA-guaranteed loans generally do not have PMI, though VA loans may charge a one-time funding fee in many cases.
For specifics on costs and cancellation rules, consult CFPB and the loan program’s official guidance.
Real-world scenarios from practice
In my work reviewing mortgage files, a few patterns are consistent:
- Borrowers who close with a 90–97% LTV usually pay materially more over the loan life due to PMI or mandatory insurance, even if their interest rate is close to market. The incremental monthly cost can delay other financial goals.
- Borrowers with 75–80% LTVs are more likely to secure competitive interest rates and avoid PMI, freeing cash flow for savings or home improvements.
- After a significant home-price decline, borrowers with LTVs above 100% (negative equity) face constrained refinance options and higher default risk; loss mitigation and loan modifications become relevant in these situations.
Appraised value vs market value vs sales price
- Appraised value: The lender-ordered appraisal value used to underwrite mortgage risk. This is the primary figure for LTV on refinances and some purchase loans.
- Market value/sales price: For purchases, lenders often use the lower of sales price or appraised value — which can push LTV higher if the appraisal comes in below contract price.
Because appraisals can differ from what buyers expect, including a buffer in your down payment target is prudent.
How cash-out and HELOCs affect LTV
- Cash-out refinance: When you refinance and take cash out, your new mortgage balance increases and your LTV rises relative to the new appraisal. This can push you into mortgage insurance territory or disqualify you from preferred refinance programs.
- Home Equity Line of Credit (HELOC): Outstanding balances on second liens add to total loan balances against the home and increase combined LTV (CLTV). Lenders consider CLTV for underwriting and pricing.
Steps to lower your LTV (practical strategies)
- Increase your down payment before purchase to reduce loan size relative to the home price. See our guide on Preparing for a Home Down Payment: Timeline and Strategies for actionable steps (FinHelp). (https://finhelp.io/glossary/preparing-for-a-home-down-payment-timeline-and-strategies/)
- Make extra principal payments after buying to accelerate equity build-up. Even modest additional monthly principal reduces LTV over time.
- Consider a shorter-term loan if the payment fits your budget — more principal applied earlier reduces LTV faster.
- Use proceeds from a sale of another property or gifts (with proper documentation) to increase your down payment when buying. See Down Payment sources and verification guidance on FinHelp. (https://finhelp.io/glossary/down-payment-sources-verification/)
- Refinance when your home value has risen and rates are favorable — but evaluate closing costs vs benefits carefully.
For borrowers with low cash reserves, targeted down payment assistance programs or shared-equity options can help; review options carefully for long-term tradeoffs.
When PMI can be removed
- For conventional loans, PMI can typically be canceled when you reach 80% LTV via payments or home appreciation; automatic termination protections may apply under the federal Homeowners Protection Act (HPA) around 78% LTV if payments are current. Check your loan documents and with your servicer for the exact process. (CFPB)
- FHA MIP removal rules differ from conventional PMI; check HUD/FHA guidance for the loan term and origination date specifics.
Common mistakes and how to avoid them
- Relying on an estimated home value when planning down payment targets — always use conservative estimates and plan for appraisal variance.
- Ignoring combined LTV when you have other liens or HELOCs. Lenders evaluate CLTV and total outstanding liens.
- Assuming rates are identical across LTV bands — small rate differences can translate into large lifetime cost differences.
Checklist before applying for a mortgage
- Calculate your expected LTV using the lesser of purchase price or estimated appraisal value.
- Compare program LTV limits: conventional vs FHA vs VA.
- Factor PMI or MIP costs into monthly-payment calculations.
- Think ahead to how quickly you can reach 80% LTV if avoiding PMI is a priority.

Final takeaways
Loan-to-Value (LTV) is one of the clearest levers to improve your mortgage cost and options: lower LTVs typically unlock better interest rates, remove mortgage insurance, and expand refinance possibilities. When planning a purchase or refinance, run LTV scenarios, include PMI/MIP in monthly cost calculations, and consult your lender about program-specific LTV rules.
