What the model considered

24 features · gradient-boosted regression

Importance is the typical share of model gain attributed to each feature group across the training set. The actual contribution to this specific prediction would require running SHAP on the live model.

Pipe renovation

Linjasaneeraus is the largest building-system replacement a Helsinki housing company performs — typical cost €25–55k per unit and often shifts the asking price.

Pipe renovation completed 1994

No imminent assessment expected; the cost is already absorbed into the asking price.
