For example, I may be incorrect in this but I'd read that the wastewater tax only applies to those actually "on Cape" so any properties on other side of canal but within Bourne or Sandwich limits would be exempt, if that's true.
The other item that I can't see Airbnb being able to determine is the CIF (community impact fee) like Plymouth voted in, as it only applies to some types of property and not others.
BTW, I tried looking at one of my listings via "private window" and am NOT seeing any reference to taxes when I put in dates to get potential cost.
The other problem (not related to tax) was that I did search on "South Chatham" and see listings from Brewster, Harwich, etc. so mine are almost invisible!
