The DTI ratio comes with two elements:

total month-to-month earnings of all of the borrowers, to your level the earnings is employed to be eligible for a the home loan (see Chapter B3–3, Income Assessment).

For manually underwritten loans, Fannie Mae’s maximum total DTI ratio is 36% for the borrower’s stable income that is monthly. The utmost could be surpassed as much as 45% in the event that debtor satisfies the credit score and reserve demands mirrored within the Eligibility Matrix.
For loan casefiles underwritten through DU, the most allowable DTI ratio is 50%.
Exceptions towards the Optimum DTI Ratio
Fannie Mae makes exceptions to the most allowable ratios that are DTI particular home loan deals, including:
cash-out refinance transactions — the maximum ratio can be reduced for loan casefiles underwritten through DU (see B2-1.3-03, Cash-Out Refinance deals);
high LTV refinance deals – with the exception of loans underwritten underneath the Alternative Qualification Path, there are not any maximum DTI ratio demands (see B5-7-01, High LTV refinance mortgage and Borrower Eligibility);
borrowers who do n’t have a credit score — the optimum ratio could be reduced for manually underwritten loans and DU loan casefiles (see B3-5.4-01, Eligibility needs for Loans with Nontraditional Credit);
non-occupant borrowers — the utmost ratio is lower than 45% for the occupying debtor for manually underwritten loans (see B2-2-04, Guarantors, Co-Signers, or Non-Occupant Borrowers about them deal); and
federal federal government mortgage loans — loan providers must stick to the needs when it comes to particular federal government agency.

Note: Fannie Mae acknowledges that loan providers may often use a far more approach that is conservative qualifying borrowers. That is appropriate so long as Fannie Mae’s minimum requirements are met, and loan providers regularly use the approach that is same comparable loans. For instance, a lender might determine a greater payment that is minimum a bank card account than just just what Fannie Mae needs, which can be appropriate provided that the financial institution regularly is applicable this calculation to any or all home loan applications with revolving debts.
DTI Ratio Tolerance and Re-Underwriting Criteria
Fannie Mae expects loan providers to possess set up processes to facilitate debtor disclosure of alterations in economic circumstances through the entire origination procedure and prefunding control that is quality to improve the probability of discovering product undisclosed debts or paid off earnings. See D1-2-01, Lender Prefunding Quality Control Review Process.
Because of the lending company’s normal processes and settings, the financial institution might need to re-underwrite the mortgage after initial underwriting. In the event that debtor discloses or even the lender discovers extra debt(s) or reduced income after the underwriting choice had been made as much as and concurrent with loan closing, the mortgage must certanly be re-underwritten in the event that brand new information causes the DTI ratio to improve by significantly more than the permitted tolerances.
The mortgage loan must be re-underwritten in all cases, if the lender determines that there is new subordinate financing on the subject property during the loan process.
Note: Re-underwriting implies that loan casefiles should be resubmitted to DU with updated information; as well as manually underwritten loans, a risk that is comprehensive eligibility evaluation should be performed.
Applying the criteria that are re-underwriting
The next actions are needed in the event that debtor discloses or the loan provider discovers extra debt(s) or reduced income after the underwriting choice ended up being made as much as and concurrent with loan closing:
Note: the financial institution isn’t needed to acquire a brand new credit history to confirm the excess debt(s). But, in the event that loan provider chooses to get a brand new credit history following the initial underwriting choice ended up being made, the mortgage must certanly be re-underwritten.
The loan is not eligible for delivery to Fannie Mae if the recalculated DTI ratio exceeds 45% for a manually underwritten loan or 50% for a DU loan casefile.
Manually underwritten loans: In the event that recalculated DTI will not surpass 45%, the home loan needs to be re-underwritten because of the updated information to ascertain in the event that loan continues to be qualified to receive distribution. Note: If the rise within the DTI ratio moves the DTI ratio over the 36% limit, the mortgage must meet with the credit reserve and score demands into the Eligibility Matrix that connect with DTI ratios higher than 36per cent as much as 45per cent.
DU loan casefiles: See B3-2-10, Accuracy of DU information, DU Tolerances, and Errors into the credit file when it comes to tolerances and resubmission demands connected with modifications impacting the DTI.
Tall LTV refinance loans: For loans underwritten prior to the choice Qualification Path, in the event that DTI that is recalculated ratio 45%, the mortgage isn’t qualified to receive distribution to Fannie Mae. If the DTI will not surpass 45%, it is increasing by 3 or higher portion points, the mortgage must certanly be re-underwritten using the updated information to find out in the event that loan continues to be qualified to receive distribution.
