Taxes are pretty stupid high in Buncombe County. We moved to Henderson County and nearly cut our taxes in half.
Mills River, Arden, Fletcher, Hendersonville all have multiple manufacturing facilities. Look into Pisgah Forest and Brevard for cities 1/2 hour away from Asheville but with amenities for everyday life. All of the aforementioned towns will allow you to locate to Henderson or Transylvania counties and save on taxes.
It's a great area to live in around here. This is where we'll be for good no question about it.
If I can get you any info, just ask.
