IFERROR helps clean up CRE variance models by replacing error codes with clear outputs like “N/A”, “Check”, “New Line Item”, or 0. It keeps variance and variance‑percentage columns readable even when prior‑year values are zero or inputs are missing, improving how underwriters interpret performance. But because IFERROR wraps all error types into one result, it must be used carefully so real formula or data issues are not silently hidden.
