Yes and no. Yes, your proposal can solve the problem for sure. No, you just can hardly implement it anytime soon. I'm in Australia and Labor lost last election just because they were swearing to remove so called NG(Negative-Gearing, which allows the property investors to offset their income with losses from investment property) before the ballot day, despite NG itself is actually a bizarre idea: why would tax payers cover the asses of the property investors and what's more, in fair amount of NG claims, the so claimed losses were not actually rendered but rather losses in accounting term. If you opt to a different accounting method, they were actually making a profit.

So your proposal will for sure hurt those vested interests, and I would expect it be very hard to pass the parliament. It's great to see Dutch cities actually made that far, I'll keep my eyes wide open to see what's next for them.
