My mother is one of 5 heirs to property that border Gonzales/Fayette Counties, just south east of Interstate 10. She is interested in selling/leasing the property so we have just begun the research on this. We have relatives in this area who have already sold/leased property and now have oil rigs on them. I hope I have used the correct terminology and I'm looking for guidance as a self-starter in this initial research phase. I also need to know how to find sources to get a fair market value appraisal,
