What Credit Score Is Used if There Are Two Borrowers on a DSCR Loan?

SHORT ANSWER
DSCR lenders often use the primary guarantor’s middle credit score when two personal guarantors are named on the loan. Some lenders may instead use the highest or lowest middle score across guarantors, and this choice can change your DSCR loan pricing. Smart Loan Savings Educational Content

Target Element NameUnderwriting Impact on Your DSCR Loan Profile
AUS Refer FindingA computer system may not be used to underwrite a DSCR loan file, so lenders take a closer look. A person underwrites your file by hand for a closer look at every personal guarantor named on the loan. This manual underwriting approach lets the underwriter weigh multiple guarantors’ credit profiles together instead of relying on one automated output. Borrowers who assume every mortgage file runs through an automated scoring system are often surprised to learn that DSCR files are reviewed by hand from start to finish. This manual approach can help when one guarantor’s score is stronger than another’s, since the underwriter considers the complete picture rather than a single number. The underwriter also checks how each guarantor’s history lines up with the property’s rental income before reaching a final decision on the DSCR loan file.
Personal Guarantor Score Selection MethodMany lenders default to the primary guarantor’s middle credit score when one person carries most of the ownership interest. When two or more guarantors share the loan, some lenders may instead use the highest mid-score among all guarantors, while others may use the lowest mid-score to stay conservative under their own Lender Overlay practices. Borrowers who assume every DSCR lender uses the same score-selection method are often surprised to learn that this practice varies across the non-QM market. Asking a lender directly which method they apply before locking a rate can prevent a late-stage pricing surprise. Some lenders may also require a personal guarantee from any guarantor holding a set ownership threshold, regardless of that guarantor’s credit profile.
Property Income CoverageLenders check if the rental income for the property covers the DSCR loan payment regardless of how many personal guarantors are named on the file. A ratio at or above 1.25 may help support your DSCR loan file when guarantor credit profiles differ. The detail many borrowers miss is that a strong property income coverage ratio can sometimes offset a weaker guarantor score, since some lenders weigh the property and the guarantor together rather than in isolation. This means 2 guarantors with different scores may still move forward more easily if the rental income comfortably exceeds the mortgage payment. Lenders may also request a market rent schedule from the appraiser to confirm the income figure used in the ratio.
12-Month Payment HistoryWith manual underwriting, lenders may check 12 months of on-time payments across all personal guarantors to help support the DSCR loan file. This means each guarantor’s recent payment record can factor into the overall file strength, not just the person with the higher score. The moment that matters most here is often when one guarantor has a recent late payment, since this can outweigh a strong middle score from the other guarantor. Some lenders may ask for a written explanation covering any late payment found in the most recent 12 months across every guarantor on file. This detail helps the underwriter separate an isolated event from a broader pattern before reaching a decision on the DSCR loan file.
The Debt-to-Income RatioThis is also called debt-to-income. Some lenders may look at your monthly bills as part of their internal DSCR program rules. When two personal guarantors are on the file, some lenders may combine each guarantor’s monthly bills before applying this internal check. Others may look only at the primary guarantor’s bills, since DSCR loans do not follow a single agency debt-to-income standard. Confirming which approach a lender uses can help you plan ahead before submitting a DSCR loan application with more than one guarantor.

People Also AskWhy These Questions Matter
Does a Co-Borrower Need Their Own Credit Check for a DSCR Loan?Each personal guarantor named on a DSCR loan usually needs an individual credit report pulled during underwriting. Lenders may then combine each guarantor’s score using their own program rules, and this combined approach can shift the loan’s final pricing tier.
How Does My Credit Score Affect My DSCR Loan Interest Rate?A higher credit score often helps a DSCR loan qualify for a lower interest rate tier. Lenders may adjust pricing based on the guarantor’s score, the property’s income coverage, and other file factors. This pricing structure can change even when 2 guarantors have similar overall credit profiles.
Can My Co-Borrower’s Late Payment Affect My DSCR Loan Approval?A single personal guarantor’s recent late payment can outweigh a stronger score from another DSCR loan guarantor, depending on lender rules. Some lenders may request a written explanation covering the late payment before finalizing DSCR loan approval for all personal guarantors on file.
