I use to have grace days- but tenants were paying all the time on the last grace day - not using it for the purpose intended but as a new date due, so new leases are being written and there will be no grace period - the rent is due on the due date, Period. As for late fees, I am being told by local attorneys that our judges in Michigan do not like to see more then $50 in late fees per month. I don't agree, but I will make the adjustment.
We are in the process of going through our first eviction case right now. Mostly because I didn't hold up to my set of standards in tenants screening. This has been a costly learning experience. But I now have a Notice To Quit printed except for the date, for all of my properties, and ready to go on the day after a late. Being burnt makes you change your ways. This is a business, strictly a business, no emotions... soon - I am still in training after 7 years. But as long as I do not repeat any mistakes, it will be okay.
Yesterday I did a dry run at the courthouse on the day for eviction cases - I was suprised to learn that 90% do not even show up to court. I will change the way I did this one too.
