Combined loan-to-value (CLTV) is a ratio that compares all outstanding loan balances secured by a property to that property's current market value. It differs from the standard loan-to-value ratio, which only measures the first mortgage against property value. CLTV includes every secured debt tied to the property: primary mortgages, home equity loans, home equity lines of credit, and any other liens. Lenders use this number to evaluate your borrowing risk before approving a second mortgage or home equity product.
A lower CLTV signals more equity and less risk for the lender, which typically results in better loan terms and a lower interest rate for you.
The formula is straightforward: add up the total outstanding balances of all loans secured by the property, then divide by the property's current appraised value.
Here is a concrete example. Your home is appraised at $400,000. You have a primary mortgage with a $280,000 balance. You are applying for a $40,000 home equity loan. Your combined balance is $320,000. Divide $320,000 by $400,000 and you get a CLTV of 80%.
Most lenders set their CLTV maximum between 80% and 85% for home equity products. If your CLTV exceeds 85%, most lenders will either deny your application or require private mortgage insurance to offset the additional risk.
Loan-to-value (LTV) and CLTV calculate the same basic relationship between debt and property value, but LTV only covers the primary mortgage.
Every lender establishes its own CLTV threshold. Many conventional lenders cap CLTV at 85% for home equity lines of credit. Some allow up to 90% for borrowers with excellent credit. Government-backed FHA loans can allow higher ratios, though the specific limits depend on the loan type and property classification.
Even if your CLTV falls within the approved range, a higher CLTV triggers higher interest rates. The lender takes on more risk when equity is thin, and they price that risk into the rate. A CLTV of 90% on a home equity loan will almost always carry a higher rate than the same loan at 70% CLTV.
When your CLTV exceeds 80%, many lenders require private mortgage insurance, even on second mortgages. PMI protects the lender if you default and the home sells for less than the outstanding loan balance. PMI adds to your monthly cost and does not reduce your principal balance. You can request cancellation once you reach 20% equity, verified by an appraisal.
A lower CLTV opens up better borrowing options. Here are the most effective ways to reduce yours:
In commercial real estate, lenders use CLTV similarly but with tighter standards. The ideal CLTV for a commercial real estate loan is typically between 65% and 75%. Anything above 75% is considered a higher-risk loan and may require additional security, a personal guarantee, or a higher interest rate. Commercial lenders use CLTV to evaluate subordinate debt requests from borrowers who already carry a first mortgage on a property.
