}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.
| Argument | Type | Description |
|---|---|---|
| price | any | Purchase price in EUR. Residential property only. |
| years | number | Term in years; rounds to the nearest whole year, halves upwards. Bank eligibility is not assessed. |
| region | string | Mainland Portugal or Madeira/Azores tax tables. |
| savings | any | Savings allocated to this purchase, including taxes and fees, in EUR. |
| tax_value | any | VPT in EUR. Zero if unknown; taxes use the higher of this and price. |
| other_debt | any | Existing monthly loan payments in EUR, included in effort rate. |
| annual_rate | number | Constant annual nominal rate (TAN), percent, not TAEG. |
| array |
| IDs from casatoo_search_locations. Resolve place names first; never invent IDs. |
