YOUR MORTGAGE, EXPLAINED

What is the difference between LTV and combined LTV?

Loan to value compares a loan amount with the property value used for the transaction. Combined loan to value considers more than one secured loan under the applicable calculation. These ratios help describe leverage, but they do not determine approval by themselves. Ask which balances and credit line amounts the lender is using.

Use matching values

A purchase price, appraisal and online estimate are not interchangeable for every program. Ask which value is accepted for the specific transaction before calculating a ratio.

See a simple example

Hypothetically, a $240,000 first mortgage on a $400,000 value is 60 percent LTV. Adding $40,000 of other secured debt makes the simple combined balance ratio 70 percent. Actual credit line treatment may differ.

Include line availability rules

Some underwriting calculations consider the full HELOC limit rather than only the drawn balance. Ask how the proposed and existing lines are treated under the loan program.

Keep affordability separate

A low ratio does not show whether you can manage the payments or preserve cash. Compare the full monthly obligations, rate changes and repayment timeline too.

Cash Out Refinance vs. HELOC: Compare Your Options

A cash out refinance replaces the first mortgage with a new loan. A HELOC generally adds a separate line secured by the home while keeping the first mortgage. Compare the whole debt picture, including a no new loan option. A lower payment can come from stretching repayment, so it is not the same as lower total cost.

Using Home Equity for Debt Consolidation: Costs and Tradeoffs

Compare the full cost and risk before moving debt onto your home. A lower monthly payment can help cash flow, but a longer repayment period can keep you in debt longer. Converting unsecured debt into debt secured by the home adds a serious risk. Keep direct repayment and other nonmortgage options in the comparison.

Why could my HELOC payment change later?

A HELOC payment can change when the rate changes, when you borrow or repay money and when the draw period ends. Some lines require different payments during repayment, and some have a large amount due at maturity. Read the actual agreement and test the later payment before relying on the initial one.
