Ask HN: Negotiating sale of property to a datacenter company

Hi HN,

A close friend is looking at selling their family farm in Colorado and he received a letter of intent from a company that builds datacenters. He suspects that water rights as well as the location play a significant role in their interest in the property, and he thinks that their offer is low all things considered. Who would he consult with to find out what the property is worth and how to best negotiate the purchase?

Thanks!
