Completed-sale information is limited, so the first challenge is deciding whether the sample is comparable at all. It consists mainly of Toronto retail units asking from about C$1,123,000 to C$1,685,000, with a typical visible market time of 82 days.
I initially suspected energy performance was separating the faster listings from the slower ones. That now seems too simple if the data crosses neighbourhood boundaries or mixes occupied space, different conditions, relisted units and sellers with different urgency. How would you divide the sample before testing the energy theory, and what evidence would help distinguish a genuine sale from withdrawn stock?
