When looking at an area like Vancouver with increasing density one must be careful using detached dwellings when formulating price-rent ratios as the earnings are forecast to increase greater than rental inflation into the future and would carry a higher price-rent ratio. The best gauge we have for a time-insensitive price-rent ratio is by using apartment rents and prices, that is, properties that have undergone most of their density increases.
Below is Greater Vancouver's apartment price-rent ratio, measured by using the MLS-HPI for apartments and the CMHC-surveyed one bedroom apartment rents, then normalizing them to a point in time.
As of December 2011 the price-rent ratio was 100% above the nadir in 2000 and 66% above the upper level of the price-rent band going back to at least 1991 (and likely longer).
As moderate stress test we can assume that the price-rent ratio will revert to at least within its historical band of 100-120 (on the graph above) in 5 years. For different rental inflation numbers the annual nominal price drops, from December 2011, required are:
- -8.5% per annum (cumulative -35.8%) for rental growth of 1% per annum
- -7.6% per annum (cumulative -32.6%) for rental growth of 2% per annum
- -6.7% per annum (cumulative -29.2%) for rental growth of 3% per annum
For reversion to the middle of the 100-120 historical band:
- -10.1% per annum (cumulative -41.2%) for rental growth of 1% per annum
- -9.2% per annum (cumulative -38.2%) for rental growth of 2% per annum
- -8.3% per annum (cumulative -35.1%) for rental growth of 3% per annum
For reversion to the bottom of the 100-120 band:
- -11.8% per annum (cumulative -46.5%) for rental growth of 1% per annum
- -10.9% per annum (cumulative -43.8%) for rental growth of 2% per annum
- -10.0% per annum (cumulative -41.0%) for rental growth of 3% per annum
The US's experience found that most price drops occurred within several years followed by a more prolonged (and still ongoing) period of flat prices and at-inflation rental growth to fully revert price-rent ratios back to their norms.
If one believes the sanctity of price-rent ratios, those are a lot of scary negative numbers.
