Thanks so much to everyone who replied - it was very insightful and definitely what I needed to hear. As an update on the situation, I ended up driving to the property to pick up a money order for the full rent amount on the 6th. I waived the late fee this month, since is the first instance this has happened, but told them that if it happens again there would be a late fee and, depending on how late, the possibility of eviction. I also mailed a receipt to them the next day with the following language at the bottom:
REMINDER:
Acceptable payment methods are as follows:
- Cozy System
- Mailing a money order
- Mailing a check
Rent is due on the first of the month, which means if you are mailing payment, it must be received on the first of the month. Payment received after the first is considered a violation of the lease agreement. If payment is not received on or before the 5th day of the month, a $25 late fee will apply and will be due along with the current month’s rent payment.
I think with my next tenants, I will be increasing the amount of the late fee, since clearly $25 isn't a large enough sum to discourage these tenants from being disrespectful. For a monetary reference, this unit rents for $675/mo.
Anyway, thanks again to all who took the time to respond. I was apprehensive since the issue seems a bit elementary but the feedback was awesome.
