Subject: 30 days Prior Notice of leaving the House or Land
I am writing this letter to inform you that I am transferred from (city name to city name). I am to report there on (date) of the next month. According to our agreement, I had to give a prior notice of 30 days before leaving the house. So this is my formal notice. I also want to request you that my advance money is returned to me on the above date because it will be very difficult for me to collect that afterward. I hope that you will accept my notice and will give my advance money back on time as per contract.
Thank you in advance.
