Question about land acrerage

[Teidra Whiteside]

Hello Everyone!

 Need a little help determining the acreage of a plot of land. I am in contact with the owner and he would like to sell as he lives in a different state and has no plans of returning to SC. This plot of land is in the most profitable side of town and if we could determine its acreage, this will be a mutually profitable deal. Problem is, he has no idea how much land he actually owns. He doesn’t even have the deed. He just knows it was passed down to him. Does anyone have any pointers on where to go and research this? Thanks!
