For many foreign investors, buying property in Portugal begins with enthusiasm: the right location, an attractive price, a promising rental yield, or the possibility of creating a long-term family base in the country.

However, one of the most important moments in a Portuguese real estate transaction often happens before the final deed: the signing of the Contrato-Promessa de Compra e Venda, commonly known as the CPCV or promissory purchase and sale agreement.

Portugal remains a prime destination for real estate investment, but the most material risks are rarely visible at the viewing stage. This article outlines what discerning families verify before buying (title and encumbrances, permits and compliance, the CPCV, condominium exposures, and cross-border tax and succession considerations) to avoid delays, hidden liabilities, and future disputes.
