I'm not entirely sure which jurisdictions you're speaking of there. Some jurisdictions like Australia and the U.K. use tax mechanisms to encourage small investors to invest by allowing them to depreciate their asset against their income or use depreciation against their income.
The challenge here, of course, is that if we want to have a rental sector, we need rental investors. We're trying to find the right balance between encouraging investment and protecting tenants. That's the soft spot we're trying to get to.
Regulation certainly can do that. I can't speak specifically to the examples because I'm unfamiliar with them.
