Just scale the tax, it’s so fucking easy to fix. But if they wait it’ll become a giant problem where some awful company or groups of company will fail and break the economy for a while etc etc.

All you have to do is scale the tax. 1 house normal tax rate. 2 houses 2x tax rate on all properties. 3 houses 3x the tax rate on all properties.

Numbers probably need adjusting but that keeps things reasonable, even for small landlords you can scale it so its fair and keeps properties local and even a good investment vehicle for individuals but prevent it from becoming an exploitive market by giants corps.
