We have come across some very detailed maps that identify precisely which 421 unfinished estates (or part of), and each of the 5,100 properties on them, are exempt from the local property tax. An example of what the maps look like is below. The red boundary denotes the exemption area, with any units inside exempt from the tax.
The maps are organised into local authority files. In the list below, the local authorities without a link do not have any exempt unfinished estates.
