Austin has some of the highest real estate taxes in Texas. I'd imagine rates are far lower for ranches in remote areas, e.g. near the Big Bend National Park (my favorite park).
You are referring to capital gain taxes right .. since all commissions and fees can be reported as expenses.
Data fees, make sure you get CME/CBOT as you want keep eyes on Meats/Grains, equipmenet, build yourself one hell of an office in your barn overseeing fishing pond you put in stock with trout that you charge by the inch over weekends for the "gamesmen" and their kids. LOL The office is part of the barn and depreciated with the farm on structures. The commissions and fees are taken off the trades usually, I don't know if they still have brokers where you pay a lump sum for futures then fees, never sounded right and I never did it. You can build a 3 hole golf course, not open on Tuesday/Wednesdays(for you) and open course other days. Do need some moola for course.
Yes, Big bend fun. Austin is BOOMING as it is new silicon valley and State capitol so have to expect it.
