I've built GIS databases w/ parcel data, owner data, tax data and zoning layers of high growth Virgnia and North Carolina jurisdiction. It's a very time consuming and ad hoc process. Some jurisdictions charge a lot of money for this data. If anyone has any interest in exploring a parcel based CRM startup concept, contact me. There is a lot of demand for this service. I have a few paying consulting customers and thinking about building it into a SaaS tool to power real estate development.
