Where in Michigan? Here's the fee schedule in my county: http://www.aacounty.org/departments/inspections-and-permits/.... Fairfax County, where my parents live is similarly expensive: about $25,000 for a smallish house.

$2,520 is what they charge for water; not sure what it is for wastewater - they may not have a public sewer system - but it's about $3,500 where I live. It used to be $150 (seriously, not a typo) and people got really upset when they raised it by a few thousand dollars all at once a few years ago.
I guess it's not a very densely-populated area and the state is surrounded by water so that might explain why it's so cheap.
