Express an interest in buying a house through email

[Valerie Stafford]

Hello,

Does anyone have tips on how to send an email expressing an interest in buying a house? I am learning the real estate investing business and have not placed any deals under contract yet, but a seller representative asked me to send an email about my interest in a property. It's a FSBO the owner is an elderly man with someone else (not a realtor) representing him to sell. I want simplicity but get the point across.

Thanks.
