Fannie Mae Guidelines: Combined Loan-to-Value Ratios

What CLTV Means for Your Mortgage Application Combined Loan-to-Value ratio measures your total debt against the property value. Unlike the basic LTV ratio that only looks at your first mortgage, CLTV includes every loan secured by your home. Say you're buying a $400,000 house with a $320,000 first mortgage and a $20,000 second mortgage from a down payment assistance program. Your LTV is 80% ($320,000 ÷ $400,000), but your CLTV is 85% ($340,000 ÷ $400,000). Lenders use the higher CLTV ratio to determine your eligibility and pricing. The calculation always uses the lower of two numbers as the denominator: the sales price or the appraised value. If you're paying $400,000 but the appraisal comes in at $390,000, all ratios get calculated using $390,000.

How Lenders Calculate Your CLTV Your lender adds up three specific amounts for the numerator. First, they take your first mortgage loan amount. Second, they include the outstanding balance on any closed-end subordinate loans like second mortgages or down payment assistance loans. Third, they add the current drawn balance on any HELOC you have. The HELOC calculation trips up many borrowers. If you have a $50,000 HELOC but only owe $15,000 on it, the lender uses $15,000 in the CLTV calculation, not the full credit limit. For a refinance where you're keeping an existing HELOC, your lender needs the exact payoff statement showing the current balance. They cannot estimate or use old statements.

Required Documentation for CLTV Verification Your lender needs specific documentation to verify every subordinate lien. For HELOCs, they require a current statement or payoff letter showing the drawn balance. The credit report alone is not sufficient because HELOC balances change frequently and credit reports may be outdated. For closed-end second mortgages, the lender needs the most recent statement showing the unpaid principal balance. If the loan doesn't appear on your credit report, you must provide documentation directly from the creditor. Down payment assistance loans require the original loan documents plus current balance information. Many of these programs have specific payoff procedures that can delay your closing if not handled early.

Why Fannie Mae Requires CLTV Calculations Fannie Mae needs to understand your total leverage against the property because it affects default risk. A borrower with 95% total debt against their home presents different risk than someone with 80% total debt, even if their first mortgage LTV is the same. The CLTV ratio also determines pricing adjustments. Higher CLTV ratios typically result in loan-level price adjustments that increase your interest rate or require additional fees. These adjustments reflect the increased risk to the lender and investor. CLTV ratios also affect mortgage insurance requirements and maximum loan amounts. Some loan programs have different CLTV limits than LTV limits, particularly for cash-out refinances and investment properties.

Common CLTV Complications and Gotchas The biggest problem occurs when borrowers fail to disclose subordinate financing upfront. If your lender discovers a HELOC, second mortgage, or other lien after they've made the underwriting decision, they must start the entire underwriting process over. This can delay your closing by weeks. HELOC calculations create confusion because the balance fluctuates. Some borrowers pay down their HELOC thinking it will improve their ratios, then use it again before closing. Your lender needs the balance as of the closing date, so any changes require updated documentation. Subordinate financing that doesn't report to credit bureaus causes delays. Some down payment assistance programs, family loans, or small credit unions don't report to all three credit bureaus. You must provide documentation for these loans even if they don't appear on your credit report. Gift funds that create subordinate liens need special handling. If a family member provides funds that must be repaid later, this creates a subordinate lien that affects your CLTV calculation. True gifts that require no repayment don't count in CLTV.

CLTV Limits and Eligibility Requirements Maximum CLTV ratios vary by loan program and property type. Conventional loans typically allow higher CLTV ratios than government loans, but this varies based on your credit score, down payment, and other factors. The Fannie Mae Eligibility Matrix shows specific CLTV limits for different loan scenarios. These limits change periodically, and some loan programs have different requirements for purchase versus refinance transactions. Investment properties and second homes typically have lower maximum CLTV ratios than primary residences. Cash-out refinances also face stricter CLTV limits than rate-and-term refinances.

Impact on Loan Pricing and Terms Higher CLTV ratios trigger loan-level price adjustments that increase your costs. These adjustments are separate from and in addition to other pricing factors like credit score and LTV ratio. The LLPA Matrix shows specific price adjustments for different CLTV ranges. A loan with 85% CLTV faces different pricing than one with 75% CLTV, even if other factors remain the same. Some lenders overlay additional requirements for high CLTV loans beyond Fannie Mae's minimums. They might require higher credit scores, additional reserves, or restrict certain loan features when CLTV exceeds specific thresholds.

Special CLTV Calculation Rules Certain loan types use modified CLTV calculations. Construction-to-permanent loans, HomeStyle renovation mortgages, and manufactured housing loans may have different calculation methods detailed in their specific guideline sections. Community seconds programs and shared equity arrangements also have unique CLTV considerations. These programs often have special eligibility requirements that affect how subordinate financing gets calculated and documented. For loans with resale restrictions or community land trusts, the CLTV calculation may use adjusted values rather than standard market values. These situations require careful coordination between the lender and the specific program requirements.
