Form letter: demand for possession for nonpayment
Re: Lease Agreement dated _ ("Lease") for _ ("Premises")
Dear _,
As of the date of this letter, you owe $_ pursuant to the Lease. This amount includes unpaid rent for the months of _, as well as certain other charges contemplated by the Lease, which the Lease provides is due and payable as additional rent. A statement showing a detailed breakdown of the balance due is enclosed. 
Your failure to pay the balance due in a timely manner leaves you in default of the Lease. You may cure that default by delivering payment in full (cash, money order, or certified check only) of the above-stated balance due to me within ten (10) days of your receipt of this letter. If you fail to timely tender payment in full as demanded herein, then I will have no alternative but to pursue the collection of this claim by any appropriate legal means. 
In addition, if you fail to timely tender payment in full as demanded herein, you have until 5:00 p.m. on the tenth (10th) day after your receipt of this letter to remove your property from the Premises, vacate the same, and surrender the Premises to me. Demand for possession of the Premises is hereby made. If you fail to timely surrender the Premises as demanded herein, I will commence dispossessory proceedings as provided by Georgia law to have you evicted from the Premises. 
As provided by the Lease, no failure by me to exercise any power under the Lease constitutes a waiver of that power, and no failure by me to insist on your strict compliance with the Lease constitutes a waiver of my right to do so. Accordingly, demand is hereby made for payment of rent and other amounts arising under the Lease, as those amounts come due. 
Finally, if I am forced to retain the services of an attorney, I will seek recovery of my legal fees and expenses. Pursuant to O.C.G.A. § 13-1-11, you are hereby notified that unless you pay the above-stated balance due within ten (10) days from your receipt of this letter, I will seek the recovery of my attorney's fees and expenses of litigation from you, along with the principal debt you already owe. 
Please be guided accordingly.
