Would you prefer only people who have additional liquid wealth be able to afford a home? To my mind that's making the problem worse: making home ownership even more unattainable than it is now.
Yes, people always need some spare income/wealth to be able to afford a home: maintenance, utilities, taxes, mortgage if any. Owning a home never guaranteed your situation wouldn't change in a way that forces you to sell. Nothing new here.
Home ownership becomes more attainable when demand is reduced and/or supply is increased. I'm totally for people living in the houses they can afford. If rich people stop hanging on the houses they cannot afford, it will both reduce demand and increase supply. So yes, it would improve affordability for the rest of us.
As for "excessively taxing" and "punishing", I'd argue the opposite:
Vancouver right now is a tax heaven for rich people who decide to keep all their wealth invested in their home, and have little income otherwise.
Let's compare to, I don't know, Switzerland, which is one place rich people like. Based on wikipedia (
https://en.wikipedia.org/wiki/Taxation_in_Switzerland).
Property tax rate in Vancouver, 2018: 0.247% (from
https://vancouver.ca/home-property-development/residential.aspx).
Switzerland: tax 0.3-0.5% of is levied on the value of all assets (such as real estate, shares or funds). That's "wealth tax". There is also "real estate tax" sometimes and that's another 0.02-0.3% a year.
Inheritance / gift taxes: none here, yes in Switzerland (with exemptions and varies; can be 30% of the estate if not a close relative).
Capital gains tax exemption for the primary residence: yes in Canada, no exemption I see for Switzerland's "property gains tax".
Delaying some taxes for decades until death? I doubt Swiss even dream of that.
Bottom line - as OP said, cry me a river. The rich homeowners have it too easy here - just compare to other cities and countries.
If this subject goes to a referendum, they won't get much sympathy from either socialists (because the rich are supposed to pay a bigger share) or from capitalists (because asset owners should be smart).
