Dear [recipient's name]:

Thank you for taking the time to provide me with an extensive tour of the property that you are selling at 5650 Sycamore Lane. I am pleased to notify you that I intend to purchase this property.

I will call you this week to further discuss the details and to initiate the formal paperwork.

Thank you again, and please do not hesitate to contact me with any comments or questions.

Sincerely,

[Signature]
