A security deposit is money you pay up front as a guarantee that you’ll follow the terms of an agreement, most often when renting a home or apartment.

Quick Scoop

  • It is a lump sum paid by a tenant to a landlord (or a customer to a business) at the start of a lease or contract.
  • The money is held as protection against things like damage beyond normal wear and tear, unpaid rent, or breaking the lease early.
  • If you meet the contract terms and leave the place in good condition, you usually get the deposit back, sometimes with interest depending on local law.
  • If there are qualifying damages or unpaid amounts, the landlord can use part or all of the deposit to cover those costs, often with an itemized explanation.

Simple example

Imagine you rent an apartment and pay one month’s rent as a security deposit before moving in.

You live there, pay rent, and don’t damage anything beyond normal use; when you move out and pass the final inspection, the landlord returns your deposit because you kept your side of the deal.
