The average house value increase is calculated on the basis of provisional data over 2006 and 2007 supplied by municipalities. For municipalities involved in a municipal redivision process on 1 January 2007, the average house value over 2006 is recalculated on the basis of the municipal redivision of 2007. Border corrections are not taken into account.
Various municipalities have as yet failed to send in data over 2007. In these cases, tax assessments are based on data referring to 2006. These assessments have been raised by the anticipated value increase. The percentages approach the new WOZ value quite accurately.
