Renting out a bought apartment
I've recently bought an apartment in Brussels. Now I'd like to rent it out and myself to move to a smaller/cheaper apartment (which I'll rent).
Is there any way to make sure I don't lose the discount off the registration fees which I received when buying my apartment (ie the 12.5% 'abattement')? I understand it is necessary to have the primary residence in the acquired property for 5 years...
