The critical defect rate within the mortgage industry has seen an increase, reaching 1.71% in the first quarter of 2026. This figure represents a rise from the 1.38% recorded in the fourth quarter of 2025. ACES Quality Management, a firm specializing in quality management for the mortgage sector, reported these findings.
