There has been so much misinformation about mineral rights and the Barnett Shale. As the pace of leasing and drilling has accelerated over the past few years it has become easier to answer many of the questions. Once the monthly checks start arriving it will become a lot clearer what the real value of owning your mineral rights actually is.
Most sellers are retaining their mineral rights if they own them... as they should. When my buyers object to this I ask them 2 questions: first, " Wouldn't you want to retain the mineral rights if YOU were selling your property?" and "What if we discover that the seller doesn't even have mineral rights?... would you change your mind about wanting the property?"
On a typical quarter-acre lot in Fort Worth the up-front bonus has gotten up to around $4,000, with monthly royalties coming in between $50 and $150. If you were to invest that income over the expected 30-year production term you would wind up with well over $100,000. So, you can easily understand why people are generally not just throwing this asset in with the home purchase.
