Does anyone know a good price for mineral interests in Section 35 10N 07W in grady county
Are you inquiring about selling or leasing?
The real answer is willing and informed buyer and willing and informed seller both agreeing on the terms. Just remember that the buyer is usually lowballing you because they want to make a profit. No harm in that, you just need to figure out how much of that you can live with.
If you are getting offers, it is probably because there are quite a few increased density hearings near you.
The offers will vary according to your royalty. 1/8th offers will usually be half of 1/4 offers.
