Are we to consider mineral rights in the appraisal of land sales and/or single family dwellings with acreage? This has come up several times in valuating rural land with oil wells. There is also the issue of the seller conveying all the mineral rights or a percentage to the buyer. Sometimes, the actual percentage the buyer will receive is uncertain or so minimal b/c pervious owners have retained the majority. Has anyone had experience with this. The area I am located in has a significant amount of oil wells and gas lines.
