TORONTO, February 6, 2012 -- The Toronto Real Estate Board (TREB), Canadian Real Estate
Association (CREA) and four other major real estate boards across Canada have
developed a new system to measure and provide clarity on home prices and home
price growth: the MLS® Home Price Index (MLS® HPI).
The MLS®
HPI is calculated using a sophisticated statistical model that is a hybrid of
both the repeat sales and hedonic price approaches. The MLS® HPI takes
into account a home’s quantitative attributes (e.g. the number of rooms it has;
square footage etc.) and qualitative attributes (e.g., whether it has a
finished basement, a view etc.).
The MLS®
HPI approach provides a less volatile measure of price than averages and
medians, which can swing dramatically in response to changes in the mix of home
sales from one time period to the next (see Chart 1 on Page 2 of this release
for a visual comparison).
Each month,
there will be two key outputs published using the MLS® HPI:
1.
A series of price indices – The MLS® HPI price indices work in a similar fashion to the Consumer Price
Index (Canada’s measure of consumer price inflation). The indices have a base month/year of January
2005, where the indices are equal to 100. In January 2012 TREB’s composite HPI was 143.6. This means that the composite price index
grew by 43.6 per cent between January 2005 and January 2012. On a month-over-month basis, TREB’s composite
HPI was up by 0.28 per cent compared to December 2011 and also up by 7.6 per
cent year-over-year in comparison to January 2011.
2.
A series of benchmark home prices – The MLS® HPI has also been used to establish benchmark homes down to TREB’s
Community level of geography for major home types including single family
(detached and attached), townhouses and apartments. A benchmark home is composed of a set of attributes
typical of homes in the area where it is located, and remains constant over
time. This allows for an
apples-to-apples comparison of price over time.
In the
coming months, TREB will publish an increasing amount of data and analysis
based on the MLS® HPI in its monthly Market
Watch publication in a new section called “Focus on the MLS® Home Price
Index”. Eventually, the MLS® HPI will
become TREB’s headline price number for release and reporting. However, traditional average and median
calculations will continue to be published in the Market Watch.
“The
Toronto Real Estate Board is extremely excited to be launching the MLS®
HPI. This new approach will provide
clarity for the consumer and prove to be a major improvement over any other
method to measure home prices and home price change available in the
marketplace today. I look forward to
discussing the many benefits and uses of the MLS® HPI in the coming months,”
said TREB President Richard Silver.

information about the MLS® HPI can be found in the TREB-specific tables and
charts on Page 2 of this release, the Backgrounder beginning on Page 3 of this
release and at www.homepriceindex.ca.

Q&A’s
Q: How is the MLS® HPI calculated?
A: The MLS® HPI is
calculated using multivariate regression analysis, a commonly used statistical
technique. Using a hybrid modeling
approach that merges the Repeat-Sales and Hedonic Price approaches, the MLS®
HPI model reflects contributions made by various quantitative and qualitative
housing features toward the home price, including:
·
Number of rooms above the basement level
·
Number of bathrooms & half-bathrooms
·
Square footage for main living & basement areas
·
Whether it has a fireplace and/or finished basement
·
Lot size
·
The age of the property
·
Parking
·
How the home is heated
·
Foundation, flooring, siding & roofing types
·
Whether the property has waterfront or panoramic
view
·
Whether the property has been sold previously (newly
constructed and previously unsold, or repeat
·
sale)
·
Proximity to shopping, schools, hospitals, police
stations, churches, sports centres, golf courses,
·
parks, and transportation (including the train
station, railways, and airports)
The MLS® HPI
can also be used to calculate the price for benchmark homes, whose features are
typical of homes sold in a given area.
Q: What is a benchmark home?
A: A “Benchmark home” is
one whose attributes are typical of homes traded in the area where it is
located, with one benchmark being generated for each supported sub-area and
home type.
Benchmark property
descriptions are based on median values for quantitative property attributes
(e.g. above ground living area in square feet), and the most commonly occurring
value (i.e. modal value) for qualitative attributes (e.g. basement is not
finished).
The attributes of
Benchmark homes remain constant over time, allowing for an apples-to-apples
comparison of price over time.
Q: How is the MLS® HPI different from average and median home price calculations?
A: The MLS® HPI
is based on the value homebuyers assign to various housing attributes, which
tend to evolve gradually over time.
This means that price
changes calculated using the MLS® HPI are less volatile than those
derived using common measures like average and median, which can swing
dramatically in response to the changing mix of home sales over time.
It is often difficult to
determine if average or median price fluctuations really reflect changes in
buyers’ willingness to pay for certain housing attributes, or just changes in
the volume of very expensive or inexpensive home sales from one time period to
the next. The MLS® HPI removes that uncertainty.
Q: How can the MLS® HPI be used with average and median prices?
A: Comparing the MLS® HPI value for a given home type in a given market with the average
selling price for the same home type and market can provide useful insights.
For example, if there is a
change in the average home price that is well above the change in the MLS® HPI value, it may point to an increase in the proportion of high-end homes sold
during a given period.
