What's Actually at Stake
A security deposit is typically one to two months' rent — a significant sum for any college student. While landlords are not permitted to pocket that money arbitrarily, they are entitled to deduct for specific, documented costs. Understanding exactly what those are — and how easily they arise — is the first step to getting your money back.
For a detailed breakdown of what landlords can and cannot legally deduct, see our guide to what a security deposit actually covers. This article focuses on the specific mistakes that most commonly lead to those deductions.
~40%
Renters who lose part of their deposit
Industry surveys consistently find that a substantial share of renters — often estimated around 40% — do not receive their full deposit back at move-out.
14–30 days
Typical deposit return window by state law
Most U.S. states require landlords to return security deposits within 14 to 30 days of move-out, accompanied by an itemized deduction list.
The Most Common Mistakes That Cost Students Their Deposit
Most deposit losses are preventable. The mistakes below follow a familiar pattern: small oversights at move-in become expensive disputes at move-out. Read each one carefully — and be honest about whether any apply to your current situation.
Skipping the move-in inspection and not documenting pre-existing damage.
Why it happens: Students are often eager to settle in quickly and assume the landlord's checklist is sufficient. Many don't realize they need their own dated record.
Leaving the apartment without a professional-level cleaning, especially the oven, refrigerator, and bathrooms.
Why it happens: Students often underestimate how thoroughly landlords inspect on move-out — or assume that a general tidy-up is enough.
Not reporting damage you accidentally caused during your tenancy.
Why it happens: It feels counterintuitive to volunteer bad news, and many students hope the damage won't be noticed or will be attributed to someone else.
Hanging things on walls incorrectly, leaving behind large holes or paint damage.
Why it happens: Students personalize their space without checking their lease's rules on wall hangings — and small nails become large patched areas at move-out.
Returning keys late or failing to return all copies, including mailbox and garage keys.
Why it happens: Students forget about spare keys made for roommates or guests, or confuse their move-out date with the last day of their lease.
Leaving utilities active or canceling them on the wrong date, resulting in unpaid final bills charged back to you.
Why it happens: Managing utility accounts is new territory for most first-time renters, and the handover process between tenants is rarely explained clearly.
Verbal Agreements Won't Protect You
If your landlord verbally agrees to overlook damage or waive a cleaning requirement, that promise may not hold up at move-out. Always get any agreements about your deposit or move-out condition in writing — a text or email is sufficient and creates a timestamped record. For more on why verbal arrangements can fall short, see our article on common renting myths that catch students off guard.
Build Habits That Protect You Year-Round
Avoiding deposit deductions isn't just about the final week before move-out — it's about consistent, low-effort habits throughout your tenancy. Things like wiping down the stovetop after cooking, reporting a dripping faucet promptly, and keeping a folder of written landlord communications all compound into a strong record of responsible tenancy.
Our habits that prevent common rental maintenance problems covers the small routines that make a measurable difference. And if you're unsure what you're actually responsible for maintaining versus what falls on your landlord, renter maintenance myths that could cost you your deposit is worth reading before you move out.
If a dispute does arise over deductions, knowing how to report maintenance issues correctly — and proving you did so — can be the difference between losing your deposit and recovering it. Most states require landlords to return deposits within a set window (commonly 14–30 days) with an itemized list of any deductions. If yours don't, you may have grounds to dispute them through your state's small claims court process.
