• Disputed accounts — may need to be removed before AUS re-run
• Authorized user accounts used as sole qualifying tradelines
• Judgments — must be satisfied at or before closing
• Bankruptcy discharged < 2 years (Chapter 7 FHA) or < 4 years (conventional)
• Foreclosure < 3 years (FHA/VA/conventional)
