The buyer pool for a pooled property is narrower here than in a warm climate market. Some buyers actively avoid a pool because of the ongoing cost and liability, and that avoidance shows up as a lower offer rather than a walked-away showing, which is why a pool rarely subtracts nothing even in a strong market.
What limits the damage is condition and compliance. A pool with a permitted safety fence, a recently replaced liner and documented service history reads as a maintained asset, while an older uninsured structure with no permit on file raises concerns during a home inspection and gets discounted further.
The buyers who will pay for a pool, typically families set on the feature or people relocating from a warmer market, are a minority, so pricing the house correctly means knowing who is likely to actually buy it. Get your hand-reviewed valuation from Joel Dyck.
