The most variances were found on Subject Debt Service Coverage Ratio, Borrower Last Name and Borrower First Name. Investor: Qualifying Total Debt Ratio variances are the difference on the percentage of income dedicated toward making debt payments. These variances occur frequently due to differences in calculating complex incomes. Investor: Qualifying Total Debt Ratio variances that were less than or equal to 300 basis points of absolute value are not included in the population below.

EXCEPTION CATEGORY SUMMARY

The table below summarizes the individual exceptions which carried an associated “B”, “C”, or “D” level exception grade. One loan may have carried more than one exception. In such cases, the exception with the lowest grade would drive the loan grade for that particular area of the review. The overall loan grade is the lowest grade for any one particular review scope (ex. a loan with a Compliance Grade of “B”, a Credit Grade of “A”, and a Property Grade of “A” would receive an overall Loan Grade of “B”).
