 l)
Each Credit Review includes an “Appraisal Review,” which means that Maxwell performed a review of the property appraisal provided by Client in connection with the HEAs to do the following:

m)
Determine whether the appraised value is supported at or within a 10% variance based on an AVM Report or other third-party valuation product.  If an AVM Report or other third-party valuation product is received but notes a variance above 10% or an inconclusive value, a field review was ordered.
 
n)
Determine whether the property meets Client-supplied eligibility requirements.

o)
Determine whether the appraisal is made on an “As Is” basis or provides satisfactory evidence of completion
 
p)
Review appraisal data for consistency with the HEA file documentation


q)
Validate that zoning is acceptable per Guidelines.
That process to arrive at a Starting Home Value was followed in a manner consistent with the Unlock Product Guidelines MaxDiligence applied a cascade methodology to determine if the original appraised value was reasonably supported when compared to an independent third party valuation product.

Exception Category Summary
 
The table below summarizes the individual exceptions which carried an associated “A”, “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 Credit Grade of “A”, a Compliance Grade of a “B”, and a Property Grade of “A” would receive an overall Loan Grade of “B”).
