Tenants that push the grace period every month

[Jennifer Clancy]

I have tenants that pay the last day of the grace period after normal business hours around 8pm.  What should I do?  I'm pretty fed up with this particular set of tenants not only are they personally inconsiderate showing up to my house at night to deliver rent right before they get a late fee, they are loud, have an unruly toddler, complain or make requests each time I see them, and they seem to break something every other month...  I'm unsure of how to proceed, how do I tell them to deliver rent at a reasonable time?
