What part of the state would you be looking at? Middle TN is rapidly changing, for the worse. Way too many people moving in changing the country/rural nature of the state. East & west TN are still fairly rural. A 70 or so mile circumference from Nashville is getting completely congested. Traffic truly sucks; last time I checked, Nashville ranked #2 for worst traffic.
No state tax (yet) but the tax structure is FUBAR. Road system has been getting worse and worse since Gov. Ned Ray McWherter left office (87-95). Things are kind of a mess and downright dangerous. Crime, especially violent crime is far worse than it has ever been. Davidson County has put some steep building restrictions in place (35k impact fee, etc...) in an effort to slow down building developments.
We have a good amount of farmland at three different locations and are very invested in the lifestyle (4th generation cattlemen). If it was not for that, Texas is where I would be moving now that we are empty nesters. We have had incredible offers for our farm south of Dickson, but I am not willing to sale knowing what would come of the land. I have lost most of my leased farmland because people are selling out while prices are high. People just do not seem to get the inflation this is causing across the board.
