Not Required to Accept Second Late Payment?

[Jason Lohse]

My tenants have been late on rent more than a half dozen times. Late last year, they were late past the 5-day grace period, so I sent a Notice To Quit. They finally paid a couple of days later. Per what I read in the Landlord/Tenant Handbook for Georgia, the Tenants have 7 days to pay after receiving a NTQ, but quote: "the landlord is only required to accept a late payment once in a 12-month period."

My Tenants are currently past the grace period again and I have just sent my second NTQ today. If I understand this correctly, I don't have to accept any form of late payment and can continue with the eviction process? Does anyone have experience with this? 

Thanks in advance!
