Canada and New Zealand are similar in that respect. There are a sizable number of people with "investment properties", but the majority of homeowners own a single home and are counting on the price to rise indefinitely to fund their retirement.
Economists and politicians regularly brag about how much 'wealth' the average Canadian has; in reality, being able to sell your house for 1.5MM isn't that much of a windfall when other houses are at least 1MM and rising rapidly, and renting is more expensive than having a mortgage.
