Just a quick couple of items to think about,
Check for any easements that are attached to the property
I would imagine you will need to run all utilities into the property. gas, electric, water, sewer etc. All can be expensive so upgrade to the most largest size and volume that you could ever need and then add 25%. Expanding or upgrading later will cost even more than the original costs to run.
Check for mineral rights on property. If you won't own them, think about what could happen if someone else wants to drill for oil or gas or mine for some minerals.
