The best time to list your home is when there is little or no competition!
But from a market perspective, Vancouver home prices are at historical highs with inventory still extremely low. The median percent of original list price is at 102% for Vancouver West and 107% for Vancouver east. This means that sellers are getting 100% (or more!) of the original list price of their home. It has been this way since December 2019, and the market has not seen a median of 100% in over 6 years.
The market does also ebb and flow with the changing of the seasons here in the lower mainland, but there are pros and cons to each season.
Many sellers do tend to list in the Spring or Summer because there are more buyers out shopping and you can typically end up getting a little more for your home.
