How is CLTV different from LTV?
Combined loan-to-value, or CLTV, considers the first mortgage together with other mortgage debt secured by the same property. It compares those amounts with the applicable property value. LTV looks at the first mortgage alone. A HELOC can also require a separate HCLTV calculation that considers its full credit limit.
A hypothetical combined-loan example
Assume an applicable property value of $600,000, a first mortgage of $400,000 and a closed-end second mortgage of $50,000. The combined amount is $450,000, so $450,000 ÷ $600,000 = 75% CLTV. These invented figures show the calculation only. They do not establish how much a lender would offer or what the payments would be.
A HELOC balance is not its credit limit
Under Fannie Mae’s rules, CLTV includes the drawn HELOC balance, while HCLTV generally includes the full line amount, even if some is unused. A small outstanding balance therefore does not tell the whole story. Confirm the lender’s method, the applicable value and any special transaction rules.
Bring every property loan into the conversation
Bring the first-mortgage balance, second-mortgage details and each HELOC’s balance and limit. Ask how new borrowing changes the combined ratio, total monthly payments and cash remaining. A lower first-mortgage balance does not by itself answer whether another lien fits the loan rules or your budget.
