Maybe you didn’t think twice when you put a big security deposit on that fancy apartment two summers ago. But now that you're getting ready to move again, you might be wondering how much of that deposit you'll actually get back. Believe it or not, your deposit isn’t at the mercy of your landlord. Tenants have rights, and landlords have limitations on what they can deduct from your deposit. And in extreme circumstances, it is one of the reasons a tenant could sue a landlord. In Florida, for example, 'if the landlord fails to return the security deposit in a timely manner, or deducts for normal wear and tear, then the tenant can sue the landlord to get their deposit back and the landlord will have to pay the tenant’s attorney fee,' says Larry Tolchinsky, a real estate lawyer and partner at Sackrin & Tolchinsky in Hallandale Beach, FL. But to avoid getting to that point, it’s important for tenants to understand the basics on deposits. In most states, the timely return of your deposit means there's a deadline—such as 30 days—so be sure to leave a forwarding address. When landlords deduct from your deposit, they will typically include an itemized statement explaining how the deposit was applied. Landlords can’t deduct from your deposit for any old reason; there has to be a legit circumstance. The rules may vary from city to city (or state to state), so read up on what your landlord can and can't do in your area. But, in general, here are some things landlords can deduct from your deposit.
