This data was extracted from http://www.realtor.com using the following search queries for different areas:
The queries were filtered to houses with 2+ baths, 3+ bedrooms, 2250+ sqft and between 0-20 years. This was further filtered to houses built on or after 2004. However after extracting I saw that there were houses with cities other than the ones uses for queries. Also, this query data was extracted on Oct 21, 2014. So it may not reflect the latest results.
Tax percent in the graph below is the ratio of 2013 tax divided by the list price
