No worries - we take this into account as this effects many tenants!
LevelCredit needs to know your real due date, even if you have a grace period.
If rent is due on the 1st of each month but you have until the 5th to pay your landlord, you will still want to put the 1st as your due date. Our system will still be able to find your payment even if you do consistently pay on the 5th of each month.
Most of the time, LevelCredit will be able to find your transaction during your grace period but if we can't find it you'll get an email from us. At that point, you can login to LevelCredit and find your payment as soon as it shows up on your bank statement.
Paying within your grace period will NOT hurt your credit or dock you as late.
