Can anyone help to write a letter about this topic:

As manager of Raspberry Collectibles, you buy antiques throughout your state. On your last trip across the state, you met with Olivia Moreno, the owner of an empty building that could be used effectively to store antiques purchased in that area. Periodically, you could send a truck to transport the stored antiques to your store. Ms. Moreno is asking $75,000 for this building. To save interest over the life of the loan, you would like to buy this property by paying five $15,000 annual payments. Write a letter to Ms. Moreno persuading her to sell you this property for five equal payments without any interest charges.

Thank you!
