• casatoo_simulate_mortgage read-only

  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.

  Parameters:

  • price — Purchase price in EUR. Residential property only.

  • region — string — Mainland Portugal or Madeira/Azores tax tables.
  • savings — Savings allocated to this purchase, including taxes and fees, in EUR.
  • tax_value — VPT in EUR. Zero if unknown; taxes use the higher of this and price.
  • other_debt — Existing monthly loan payments in EUR, included in effort rate.
  • annual_rate — number — Constant annual nominal rate (TAN), percent, not TAEG.
  • young_buyer — boolean — True only if every buyer qualifies for IMT Jovem: age up to 35, not IRS-dependent, first primary home, no residential ownership in prior three years.
