How these charts were made
The Montreal Real Estate Board keeps data on every home sale on the island. We obtained the number of sales, the average asking price, and average selling price for each property type, by quarter, in several neighbourhoods. The MREB also calculates the ratio of selling-to-asking price for each one.
Using data visualization tools, mostly Microsoft Excel and Tableau Public, patterns were spotted in those ratios between neighbourhoods and across quarters. The implication is that that with certain properties and certain neighbourhoods, sellers price homes either far above market demand or close enough to what buyers are willing to pay.
Although the MREB provided data on 77,000 sales since 2008, the average quarterly prices were only calculated in neighbourhoods that registered more than 30 sales in one quarter for each property category. As such, data from 11,000 sales were not calculated.
No data were provided, for any quarter, for Baie d’Urfé, Hampstead, Dorval Island, Montréal-Est, Montréal-Ouest, Sainte-Anne-de-Bellevue, and Senneville.
Other neighbourhoods may have registered enough sales in one property type, but not another. For example, Rosemont had plenty of condo sales, but hardly any single-family home sales. As such, comparisons between neighbourhoods should be done with prudence.
