Sample Apology Letter for late Payment of Rent

To,
Mr. Chairman,
Carl Sheng Stole System,
California, United State of America.

Subject: Apology for late payment of rent of office

Respected Sir,

It is to state with due reverence that I am Arthurs Bee, a resident of Kenley society. Couple of years ago, I had taken out a building from you on rent. I had made that building into my office and as per agreement between us. The rent for the whole first year was given to you, but due to certain private issues of my own, I was unable to pay the rent for this current year on the time. I really feel guilty so I apologize for my act.
Kindly accept my pardon and the late cheque. Thank you and looking forward for a kind action.

Yours Truly,
Mr. Arthurs Bee,
