compare_locations
Read-only
Compare real estate transaction statistics across multiple Polish districts side-by-side, including median price per m², average area, and transaction counts.
Instructions
Compare real estate statistics across multiple locations side-by-side. Provide 2-5 district names to compare median price/m², average area, and transaction counts. Use list_locations first to find valid location names. Requires at least one filter besides districts (e.g., propertyType). Example: compare Mokotów, Wola, Ursynów for apartments. Note: median/average prices are market-based — fractional ownership shares and non-market deeds (public tenders, foreclosures, privileged/subsidized sales) are excluded from price aggregates. Transaction counts and coverage stay complete.
