A mainstream provider has made the tax rolls available to its customers!

http://www.propertyradar.com

You have to search by property address only, not by owner name.

Casual users might not get enough benefit to warrant paying the $50 per month membership dues, because most of this data is available for free from your realtor or other sources.  But it is nice to see it all out in the open!
