Start with the equity question, since it usually decides whether an upsize is financially possible before it decides whether it is desirable. Online estimates and public records cannot see a renovation done without a permit, so your actual equity is often higher than a generic number suggests, and that gap only shows up in a proper walkthrough.
Then look at timing rather than just desire. A mortgage renewal or a scheduled income change lines up naturally with a move, while selling mid-term into a penalty adds a real cost on top of everything else. With Saskatoon's benchmark price at $444,700, run the numbers on both homes together rather than deciding on the current one alone.
