Contact a local agent - someone who speciallizes in land sales - it's a bit trickier than developed residential homes.
And take Patricks advice to heart - BE CAREFUL!
out of the three listing agent only one had a phone number.
None of the property`s had a offered price. ZERO
I think you live in a one horse town, or at least a one realtor town. I don't think they use buyers agents.
You will have to call a local Realtor.
Be careful, Good luck
