Charge late payment fee, not interest.
Tenant called me on the 28th and said that his Boss (he is a painter) had a stroke and his girl friend won`t be paid until the 5th.
I issued the N4 and will charge 25$ for late payment. I also added this in my rental agreement, that I will charge on late payment and 40$ on NSF cheques.
My bank wants an on time payment, too!
