I would like information on who to contact for an appraisal in Martin County? I am in need of a basis value for my holdings in Martin County, Section 9, Block 35, Township 1 North, Texas & Pacific Railroad Company survey, A-45, N/2 and SW/4, from inheritance in 2011. Would like a value with production and non-producing. I just sold some interest but retained current well production so what I sold is non-producing. Any help with this would be greatly appreciated.
