LEAP is a third party cosigner that fills in for a personal guarantor, allowing you to sign a lease where you otherwise would not qualify. In order to sign through LEAP if you are a non-student, you will go through the application process on leapeasy.com. Once you have applied, they will run a credit and background check to determine the fee to guarantee the lease term. If you are a student who does not provide a guarantor, you will be automatically enrolled in LEAP and a monthly fee will be added to your lease.
