CALGARY Royal LePage is predicting a slight increase in detached home prices and a modest decrease in condominium prices in Calgary in 2021, as well as stable prices in the Edmonton market. According to the group s market survey forecast released Monday, the aggregate price of a home in Calgary next year is expected to be $469,600 a 0.75 per cent increase over 2020 and the median price of a two-storey detached home is pegged at $514,800, a jump of 1.5 per cent compared to 2020. The stabilized price prediction is due in part to a decline in listings at the start of the year as well as the expected rise in demand for homes as interest rates remain low.
