How to lose 2500$ without passing through Vegas

You go live in Belgium and buy an appartement. The government promises you a discount on the purchase taxes if its rateable value stays under 1000$. It does, but then during the 4 months waiting periode between the bidding and actual buying they increase the rateable value from 750 to 1011$. Which means that next Saturday when I'm signing the papers, I can make no claim for a discount anymore. Bam! 1300$ gone.

The government also promise a subvention for the environment friendly renovation of a window. But only if your mini-appartement's rateable value stays ... under 1000$, indeed. Fuckers! Now I can work 250 hours extra on my weekends just to make up for these unforeseen expenses. I have no idea how the state all of a sudden rates my 52 m² appartement in Ostend higher than my sister's villa in the center of a sleepy town.

PS: I pay in euros of course. But dollars just sound so much more dramatic. Imagine 'For a fistful of euros', what a bad movie that would make.
