Everyone seems to agree that speculation in housing is a global problem with adverse effects on communities and societies. Toronto seems to be a good example of how the end-game will look like.
People are priced out of owning a home for good and/or have to leave places where they might have been living for their whole life.
Rent controls don't seem to work, and just cancelling (by whatever means) the market for real estate in general might yield a lot of unwanted side-effects.
I believe there are 'simple' measures to curb rampant speculation without distorting the market to badly:
- Disallow foreign investment in residential real estate.
- Disallow for-profit corporations to purchase residential real estate.
- Stop subsidizing speculation by bailing out real estate investors
- Invest in infrastructure so that living apart from big cities is more worthwhile. Especially broadband internet and schools.
- Add a tax penalty to vacant residential real estate.
