Analysis Tools

Calculators, short questionnaires and municipality data for a purchase in Portugal. Every card opens a tool that is available now.

IMT Calculator

Estimates IMT and Imposto do Selo on the price you enter, using the 2026 tables, and shows the notary and registration amounts in the result. Covers the mainland and the autonomous regions, a permanent home or a second home, IMT Jovem, and non-resident buyers.

Calculate tax

Real Cost Check

From the price and buyer profile you enter, estimates IMT, Imposto do Selo, notary and registration, plus a first-year amount for IMI, insurance and condominium. It uses the price you type. It does not look up the VPT.

Estimate the cost

True Ownership Cost

Acquisition costs on the same IMT model, plus IMI, insurance and condominium. Signed-in users also see a three-year cash outlook with a maintenance reserve.

Estimate costs

Mortgage Fit

Estimates the monthly payment from the price minus the deposit, compares that payment and other debt with gross income, and shows a rough LTV warning. It is not a bank decision.

Estimate the payment

Buyer Launchpad

A step-by-step checklist for buying in Portugal: NIF, bank account, visa path, tax residency, and the steps from contract to deed. You need to log in to use it.

Simplex questionnaire

A questionnaire about the property — build date, Licença de Utilização, changes, and whether the areas match — that estimates unlicensed-works risk under DL 10/2024. It does not look up the licence or the council.

Open the questionnaire

Reality Gap samples

Shows sample profiles. They illustrate a gap between the registered legal state and the likely physical condition. It does not score a real property, and it does not read the VPT or comparable sales.

Jurisdiction Mapper

Choose the buyer’s nationality and the stage of the purchase. It compares hidden-defects liability under the Portuguese Civil Code with what a buyer of that nationality may expect. It does not read an address or a zoning map.

Map jurisdiction

Seismic zone

Seismic zone and ground acceleration for an address on mainland Portugal. It is not a property-level risk score.

See the zone

Where should I buy?

Pick a municipality and see a score built from stored official data: prices, IMI, climate risk, Alojamento Local and energy. The figures are for the municipality, not for one property.

Open the municipality

Compare areas

Compare two or three municipalities side by side on stored municipality data: prices, IMI, flood and wildfire, rental and Alojamento Local, construction, and energy.

Compare municipalities

Asking price and the INE median

Compares an asking price per square metre with the municipality’s median sale value per square metre from INE, for all homes, new homes or existing homes. It is municipality context, not a valuation of the property.

Compare with the median

Municipalities by criteria

Set a region, an INE price ceiling, Alojamento Local rules and an optional flood class, then sort municipalities by the criterion you choose. A municipality with no data for that filter is left out. It is not a list of the best places to live.

Filter municipalities

New construction by municipality

Dwellings licensed and dwellings completed, by municipality, from INE. A licence is not a start and not a completion, and the figures are not for a street or an address. Some municipalities also list named projects from a public source that was checked. That list is not complete.
