Buying land in Castro Marim as a foreigner

There are no nationality restrictions on buying land in Castro Marim — EU and non-EU buyers follow the same process: get a Portuguese tax number (NIF), sign a promissory contract, then complete the deed before a notary. What matters most is whether a specific plot can actually be built on — the municipal PDM and national RAN/REN restrictions decide that, not the listing label.
