Varies from sate to state. Here, several school systems in counties with very low population get their funding almost entirely from business equipment and inventory tax. States with very low population density and lots of AG land (usually taxed at 50%) simply cant generate enough revenue through property tax.
And I couldnt agree more about the boondocks. Our shop is on a main road but in a rural town (pop. <1000) about 35 miles outside the nearest city. We have been somewhat courted several times to move into the city into some very attractively priced, very large, and very well equipped, commercial space. While the pricing to buy these spaces is very attractive, as you say, they dont outweigh the benefit of tax rate, B&O taxes, employees being assessed city user fees withdrawn from their weekly pay, and so on. Not to mention Division of Labor and OSHA being on top of you all the time.
