Common Mistakes to Avoid
❌ Withholding deposit improperly
Landlords can only deduct for unpaid rent and damage beyond normal wear and tear. Cannot charge for normal aging of carpet, walls, etc.
❌ Missing return deadline
Most states require return within 14-30 days of move-out. Missing deadline can result in penalties of 2-3x the deposit amount.
