A tight supply figure like 1.63 months means less competition from other sellers for buyer attention, which generally favours listing sooner rather than waiting for conditions to change on their own. Waiting is a bet that the market improves further, and that bet carries real risk if supply loosens instead.
Your own timeline should carry real weight too. A condo held for personal reasons, like waiting out a lease or a job transition, is a different decision than one held purely to chase a better number, and the second is harder to time correctly than most sellers assume.
Condo fees and any pending reserve fund special assessment can also change the math on timing, since a known future cost is often better dealt with before it shows up in a buyer's due diligence. Get your hand-reviewed valuation from Joel Dyck.
