Average housing prices increased by over 125% between 1996
and 2006. The key projects showed a remarkable surplus value
compared to the reference projects in terms of the real estate value
of housing (Table 3): if we correct for differences in regional development,
transaction costs for owner-occupied housing in the key
projects rose more than those in reference projects over the entire
period. The picture is only mixed for the 1996–2001 period, particularly
for the second-generation projects.
