My lease provides for $15 per day late fees. Once I pay the RENT due, can the landlord continue to accrue late fees ON the late fee? For example, rent is $600. I am 4 days late ammounting to $60 late fees. The TOTAL now due is $660. I paid the $600 rent but not the $60 late fees. Can late fees continue to accrue on the $60? Or do the late fees stop since the principal amount of rent was paid?
