The short answer
The best time to sell depends on unit type, building, price position, competing supply and actual buyer absorption. A seller should look at registered transfers and the local handover pipeline before choosing a listing window, rather than treating a broad market headline as a personal exit strategy.
Read the supply window
New completions compete directly with resale stock. Focus on what will be delivered in your building, micro-market and unit type—not only a citywide figure.
Price to the register
Asking prices are not evidence of cleared demand. Use registered transfers and condition-adjusted comparables as the starting point for a listing decision.
Model the full exit
Before a price conversation, quantify the expected agency, NOC, mortgage-discharge and charge-clearance costs. Gross sale price and net proceeds are different numbers.
