If you found it, it's likely that other buyers will find it as well. The buying process really is intended to protect the right of all parties. Showings, inspections, surveys, disclosures etc. are but a few of the means by which buyers rights are protected.
Your intentions are well intended but likely unnecessary.
I see no one has answered your question. Although I'm not in your area, I would suggest contacting a local Realttor that specializes in land. Hopefully he can help you find the 1 acre parcel you desire.
