The eastern Algarve
Portuguese purchase process
You need a NIF tax number, usually a fiscal representative if you are non-resident, and a lawyer. The process runs through a promissory contract (CPCV) with a deposit, then the deed. A flat 7.5% IMT for non-residents was introduced in 2026, which means non-resident buyers should check the current rate; stamp duty and registration fees are extra. The golden visa property route closed in October 2023. Verify planning status of any rural property. See the Portugal page, villas and financing.
