We estimate that around 15% of the total properties that are vacant will be liable for this tax. We estimate on the basis of the survey that we have done that the total number of vacant properties is 57,000.

Of those properties, we estimate that 15% will be liable to the tax. That is approximately 6,000 to 7,000 properties.
