If Canadians have a preoccupation these days, apart from the winter weather, it seems to be real estate. Specifically: the ever-rising prices in most of our big cities.

Is this a bubble? Will there be a crash, or a so-called soft landing? No one really knows.

For generations, we've cultivated the home-ownership dream — the idea that rising house prices are a measure of the country's overall prosperity and one's own financial security.

Buying a home is what you do as an adult — it is how you settle down and raise a family.

It's also a good investment, and often a ticket to a secure retirement. Social pressure, government policy and, recently, historically low interest rates have encouraged all of that.

But maybe those are now outdated notions. Many young Canadians are already looking at them with skepticism. And perhaps we should all rethink the dream for a number of reasons.

First, affordability. In little more than a decade and a half, the average house price in Canada has more than doubled, outpacing inflation and incomes.

In Toronto's super-heated condo market, for example, what's called a micro-condo — 300 square feet — can go for a cool quarter of a million dollars.

Realistically, for the average Canadian, the dream of owning a home is beyond reach in cities like Toronto, Vancouver and Calgary.

Some Canadians are spending as much as 50 per cent of their income on mortgage payments, and as consumers we've never been more indebted. Mortgage debt is a big part of that.

Dragons' Den panelist David Chilton, perhaps best known as the author of the Wealthy Barber, a folksy how-to about financial planning, is worried about our real estate obsession.

"I'm not against real estate," he says. "I'm against the fact that so many people have it as their primary asset, their only asset in a lot of instances. That's not good diversification. It's not wise"

What's more, Chilton argues that too many of us have bought into the idea that bigger is better — what he calls the granite countertop phenomenon.

"How screwed up has society become," he asks, "when people are literally embarrassed if they don't have granite countertops?"

Chilton boasts about living in a fairly modest 1,300 square-foot house, and claims not to know what kind of countertops are in his kitchen.

"My argument has always been a more modest home is a better way to live," he says. "You're not stressed about your financial future.You have enough money flowing through to save. And it's easier to keep clean."

As he, and other financial gurus, point out, Canadians are spending so much on their mortgages that they have little or nothing left for anything else, particularly savings.

Rob Carrick, who writes a personal finance column for the Globe and Mail, notes that housing affordability is one of his most frequent subjects.

What he worries about are those who are maxing out on debt. "What about saving for retirement? What about saving for your kids' education?" he asks.

"We all have aging parents.We may well be supporting our post-university kids and our aging parents. If we're loaded down with heavy debts, I question how much longer it will all work?"

A second concern in this debate is the notion of real estate as the dream investment.

Carrick calls it a great story. But, he says, it's one that is out of sync with the times.

"That housing-is-a-great-investment story is for people who bought five, 10, 15, 20 year ago. For today's buyers, I think five years from now your house might well be worth what you paid for it."

No less than the Nobel Prize-winning economist, Robert Shiller, questions the value of homeownership as an investment. He's a renter.

"Here is the harsh truth about homeownership" he wrote in the New York Times. "Over the long haul, it's hard for homes to compete with the stock market in real appreciation."

What's more, housing is an "ambiguous investment to evaluate," he says, because it's an emotional investment, not just a financial one.

Even if we accept the fact that owning a home may not be the lucrative personal investment it's often made out to be, another reason to reassess our fixation with homeownership may be because of its broader economic implications.

Research in the U.S. has shown, for example, that states with high rates of home ownership correlate with high levels of unemployment.The explanation being that if workers own a home, they're less mobile, less likely to move to find work.
