Combined Loan-to-Value (CLTV) looks at the total amount of debt secured by a property, not just the first mortgage. That includes:
The basic formula is:
CLTV = (Total of all loan balances secured by the property ÷ Property value) × 100
"Property value" is usually the lower of the purchase price or the most recent appraised value, depending on the lender and the purpose of the loan.
Imagine a property that is worth $500,000. The owner has:
Total debt secured by the home is $350,000. The CLTV is:
$350,000 ÷ $500,000 = 0.70, or 70%
That means 70% of the property's value is tied up in loans, and 30% is equity the owner holds.
It is easy to mix up CLTV with Loan-to-Value (LTV). The difference is:
For example, if a buyer is taking a $350,000 first mortgage on a $500,000 home with no other loans, the LTV and CLTV are both 70%. If that same homeowner later opens a $50,000 HELOC and uses it, the LTV on the first mortgage is still based on $350,000, but the CLTV becomes 80% when you count both balances.
Different lenders and products have different CLTV limits, but broadly:
Lenders may also cap CLTV differently for cash-out refinances, investment properties, or other higher-risk scenarios.
CLTV is one of the key risk indicators lenders use when they decide whether to approve a loan, how much to lend, and what terms to offer. It connects directly to three things borrowers care about: approval odds, interest rate, and how much flexibility they have in the future.
When a lender reviews an application, CLTV sits alongside income, credit history, and property type. A lower CLTV generally tells the lender:
For the borrower, a lower CLTV can often contribute to:
Your CLTV is a quick snapshot of how much equity is available and how much of the property's value is already pledged to lenders. That snapshot influences:
Monitoring CLTV over time can be helpful. As loan balances are paid down and property values move, CLTV shifts. Many borrowers track it before they apply for a refinance, a home equity loan, or a line of credit so they are not surprised by a lender's response.
For buyers and homeowners who want to strengthen their position, there are practical ways to improve CLTV:
Thinking in terms of CLTV helps align borrowing decisions with long-term goals instead of viewing each loan in isolation.
