A lower months-of-supply figure generally favours a seller, since it means fewer competing listings relative to buyer demand, but a two-family home is a narrower market than a single-family house, so the general city figure only tells part of the story for a property like yours.
New listings are also running well above the same period last year, which means more competing multi-family inventory may be coming rather than less, and waiting to see if conditions improve carries the real risk that they simply get more crowded instead.
The better question is whether your specific building, priced correctly today, sells well right now. Get your hand-reviewed valuation from Joel Dyck.
