DearJUSTIN HOLLOWAY

I am of course flattered that you sought out my advice, but I am afraid that I cannot provide it. I have very limited knowledge in the field of farm and ranch real estate, and as such could not provide accurate guidance.

I would suggest that you talk to my colleague, David Owen. David has many years worth of experience dealing with this area of real estate and can provide you with all the information that you require. I have enclosed his business card and would suggest that you give him a ring.

Many thanks for considering me and I know that with David’s help your venture will be successful.

Sincerely,

Ferdinand
