like u said "it all depends on the location and what all comes with the lease"
we have leased out west (well west of i35) and in grant co we find leases for 7-10 an acre but going rate out there can be as hi as 15per. The lease im getting this year (which is posted on here) is in NE Ok and it only $3.33 an acre but thats cheep... anywhere in the state u can find land from 5-10 an acre if u really look but the sky is the limit on leases and some lucky people can get a full section for $100 total so u never know
It seems like everything I see is $10 or higher.
