The above is great. The mineral rights should come with the land. Mineral rights can be held by a third party.
Best that you have them and have control over the land. If you really love the property but don't get the rights have setback rules put into the deed. No drilling within 1000' of primary residence. No storage tanks
on property and so on. In NYS you are talking natural gas. This was really hot a few years back but really has fallen by the wayside since the Gov put a stop to fracking.
Good luck-I bought 56 acres 8 years ago and never looked back. Call the DEC the were very helpful to me answering many questions.
