“Affordability is a key variable. It gives you a lot of information,” says CIBC deputy chief economist Benjamin Tal. “When affordability is good, demand usually exceeds supply.”
Affordability – a type of debt service ratio – gauges the average percentage of income needed to carry a mortgage. This is closely linked to how much homeowners can borrow.
It’s a rather paradoxical statistic. You would think, for instance, that with home prices doubling in the last 10 years, affordability would be getting worse.
But with soaring debt levels, doesn’t it seem counter-intuitive that folks could “afford” such elevated home prices? It might, but affordability doesn’t measure home prices or total debt.
Low rates have been pivotal for consumers. They’ve kept interest payments, as a share of disposable income, at just 7.2 per cent, Mr. Tal says. That is below the long-term average of 7.6 per cent and well under the 10.7 per cent level from 20 years ago.
Cheap rates have also supported bigger mortgages. If we look at mortgage payments from two decades ago, a typical single job holder with 10 per cent down and minimal consumer debt qualified for a $96,000 mortgage.
Today, he or she could get a $285,000 mortgage - almost three times as much.
(This assumes a 25-year amortization and standard lender assumptions for debt ratios, property taxes and heating costs. It uses Statistics Canada data for wages and estimates of five-year fixed mortgage rates based on Bank of Canada data.)
That might be little consolation to folks living in places like Vancouver or Toronto, which are exceptions to affordability. But the fact remains that overall, low rates give borrowers tremendous leverage.
Leverage is something the Bank of Canada is understandably concerned about. Cheap money means “cheap” debt payments, and it’s awfully easy to get complacent.
When rates do eventually take the elevator up, real estate is going to feel it.
House prices will almost certainly roll over when interest rates rise, BMO senior economist Sal Guatieri said in a recent report.
“A 2 per cent rate increase would put enough strain on affordability to slow the market meaningfully,” he said. “It would encourage many first-time buyers to just rent.”
