Lob,
depends on your nationality (non-EU) to take it with you from June 1st this year.
Also your pension statement will show what you can put towards a property purchase either as cash or as a charge against the fund so you don't have to top it up again on sale.
Going thru the process myself at the moment (property).

Oh and of course from you can put it towards a company. For a personalunternehmung the pension doesn't have to be transferred, however if you make a gmbh the pension goes with it.
