    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Estimate Portugal residential purchase costs with the same logic as the Casatoo calculator: 2026 mainland/island IMT, youth relief, stamp duty, loan payment, savings shortfall, effort rate, rate scenarios and annual amortisation. Anonymous, read-only, no account or location lookup needed. EUR amounts; TAN is percent. Omitted fields use published illustrative defaults, not known facts about the user. Include assumptions when presenting results.
