Repeat-sales difference-in-differences: the dependent variable is the first difference of the price equation between sale and resale (log form implied by magnitudes; CAD conversions in text equal coefficient x mean price change of about CAD 45,500), so time-invariant structural and location characteristics are differenced out. Only two kinds of hedonic coefficients exist: the renovation grant dummy and the policy-proximity buffer dummies (mapped to 'other', x_transform 'other'). No standard errors printed, stars only with a non-standard legend (* p<0.05, ** p<0.01, *** p<0.001). Limited usefulness for structural pooling; keep for heritage/landscaping policy evidence."
