A successor to the home ownership subsidy
I am not aware of any. However, depreciation or special expenses for monuments / redevelopment areas §§ 7i, 10f Income Tax Act are still available, which are interesting for renovating existing buildings.
In addition, there are the "craftsman services"; as of January 1, 2009, 20% of 6,000 euros for maintenance and modernization work – that is 1,200 euros of separately stated labor costs.
