Late Payments: Fake lates (e.g., paid on time but reported late).
Derogatory Marks: Old collections or charge-offs beyond 7 years.
Unauthorized Inquiries: Hard pulls without permission.
Medical Debt (2026 Rules): Often removed if <1 year old or paid; dispute unpaid bills under $500.
Collections Not Yours: Fraudulent debts.
Bankruptcies Errors: Wrong dates or chapters.

Mini Case Study: Jane spotted an unauthorized inquiry from a loan she never applied for. After disputing, it was removed, boosting her score 50 points and securing her mortgage at 4.5% instead of 6%.
