Kate, I'll reference 19518 zip code specifically here. Douglassville (Amity Twp) has seen huge growth in the last 10 years due to all the new home developments going in. These new homes have terribly strained the infrastructure - just look at the traffic jams on Rt 422 going towards KoP. To cope with all these new homes, Daniel Boone School District has had to build new schools, funded by all the taxpayers. Amity Township has also had to hire more police, and improve the local roadways (not counting state + federal roads). At the same time, new industry hasn't moved in to take some of the burden. The 1992 baseline for property taxes doesn't help Amity either, as such a large proportion of the area is new construction. If you are looking for lower taxes, look at some of the older homes in Amity Gardens or in Monocacy Station.
