DTI Ratio Calculator

Front-end (housing) and back-end (total) debt-to-income ratios per Fannie Mae Selling Guide B3-6-02 and Freddie Mac Single-Family Seller/Servicer Guide 5401.2. Classifies the back-end ratio into a standard-manual / extended-manual-compensating-factors / DU-LPA-only / exceeds-max tier and flags whether the loan is within the max DTI for the selected underwriting type (DU, LPA, or manual). Feeds art-222-agency-eligibility-matrix as one of its DTI inputs. Not check_agency_eligibility_matrix itself, which performs the full multi-check eligibility decision.
