Fees can vary depending on your landlord's settings. Many landlords cover service fees for payors while others pass some or all service fees on. The best way to confirm what you will owe is to create a free account and go to the "Add Payment Method" window. There you will you see how much (if anything) is being charged.
Okay, so then what is the most that I could possibly have to pay per payment?
Standard Service Fees:*
Bank account payments via ACH = $1.95
Credit Card and Debit Card payments = 2.99% fee
