Hello Tom. Why is this an important question for you? The area comps on the current market of your area, in this case, Calgary, are available through any real estate professional in your area. You can ask to search for a window of 3 months, 2 months, 1 month, and you're right, the system default is set at 6 months. But if you don't like the six months view, go for the one month window. What do you propose to do with this information? If you check the variances between the 6 month window (for the area of interest) and the 2 month window for the same area, you will find a small difference, up or down. This difference, unless you're in a particularly severe recession or inflation will reflect a small percentage increase or decrease, between 4-7%. Is that significant enough to impact your buying decision? Perhaps. But the best source for the demographics in your area, unless you're willing to pay a lot of money for up-to-date timely data from a research firm, is still your local realty office. Hope this helps.
