Letter of reply to loan letter

Dear Paul

I am writing in response to the letter you wrote asking about the loan I made. I do appreciate your letter and your concern. I am making every attempt to find the resources allowing me to repay you as quickly as possible. At this time I can only afford a small amount each month. I know this is just a start, and I plan on increasing the amount as soon as I can.

I am hoping to pay back the loan as quickly as possible and understand your situation. I apologize for my inability to reduce the amount and promise this will change shortly. Meanwhile please accept this small payment on the loan as a start.

Thank you for your time and patience.

Sincerely
Jack Hammer
