Section 20, Township 8 North, Range 5 West

Hi all,

What is a reasonable valuation for Section 20, 8N 5W? We have received lease offers ranging from $2500 to $4500 per acre, 1/5 royalty. For outright purchase, the ranges are between $5500 to $9800/acre. How do we confirm these values?

Thank you,

Caryn
