Loan-to-Value (LTV) Ratio
Compares a mortgage loan amount to the appraised value of the property, a key factor in loan approval and interest rates.
Interpretation
LTV (%) = (Loan Amount / Appraised Property Value) × 100. Measures the risk of a mortgage. Higher LTV means higher risk for lenders, often requires mortgage insurance.

What it means
The Loan‑to‑Value (LTV) ratio is the percentage of a property’s appraised value that is financed by a loan. It is a key risk metric for mortgage lenders; a higher LTV implies less equity and greater default risk. LTV affects loan terms, interest rates, and the need for private mortgage insurance (PMI). In real estate, LTV is used by both borrowers and lenders to determine loan eligibility and to structure financing. Understanding LTV is essential for homebuyers and real estate investors to manage leverage and to negotiate favourable terms.

Common mistakes
- LTV ratio: Loan amount divided by the appraised property value – expressed as a percentage.
- Loan amount: The total mortgage amount (or other secured loan).
- Appraised value: The market value of the property as determined by an appraiser.
- Higher LTV: Higher risk for the lender – may require mortgage insurance.
- Thresholds: Often, LTV above 80% requires private mortgage insurance (PMI).
Applications
Loan‑to‑Value (LTV) ratio is the loan amount divided by the appraised value of the collateral (e.g., property). It is a key risk metric for lenders, indicating the cushion against a decline in value. Mortgage lenders use LTV to determine borrowing capacity, to set interest rates, and to require private mortgage insurance (PMI) when LTV is high. Homebuyers use it to understand down payment requirements and to negotiate terms. LTV also affects refinancing options and equity access. By managing LTV, borrowers can reduce borrowing costs and improve financial stability. This ratio is central to real estate finance and commercial lending, guiding risk assessment and pricing decisions.

Frequently Asked Questions
LTV (%) = (Loan Amount / Appraised Property Value) × 100. It measures the proportion of a property's value that is financed by a mortgage. A lower LTV means more equity and less risk to the lender.
Lenders use LTV to assess default risk. A high LTV (e.g., >80%) means the borrower has little equity, increasing the lender's risk. This often requires mortgage insurance and may result in higher interest rates.
For conventional loans, LTV limits are often 80‑97% depending on the program and credit score. FHA loans allow up to 96.5% LTV. VA loans may allow 100% LTV (zero down).
A higher LTV is riskier for the lender, so it typically leads to a higher interest rate. Some lenders charge a premium for LTV above 80% to compensate for the increased risk.
PMI is insurance that protects the lender if the borrower defaults. It is usually required when the LTV is above 80% (for conventional loans). The cost is added to the monthly payment.
If the property value increases, the LTV decreases (since the denominator grows). This can allow the borrower to refinance to a lower rate or remove PMI when LTV drops below 80%.
CLTV includes all liens on the property (e.g., first mortgage plus home equity loan) against the property value. It is used when there is more than one loan.
Same formula: Loan Amount (new mortgage) / Appraised Value. For a cash‑out refinance, the new loan amount is higher, which may increase LTV.
- Using the purchase price instead of the appraised value (appraised value is the correct denominator).
- Ignoring PMI costs when calculating the total cost of a high‑LTV loan.
- Assuming LTV is the only factor in loan approval – credit score, income, and debt‑to‑income also matter.
Home equity is (1 − LTV) × Property Value. A lower LTV means more equity, which can be tapped for future borrowing or as a financial buffer.
