Long-term rental This 5-bed house in Cascais e Estoril presents a compelling long-term rental opportunity, positioned 14.7% below its fair value of €1,089,086. The 5.4% gross yield alongside an 82/100 condition rating makes it attractive for stable, long-term tenants looking for quality housing. Family rental Given its size and location, this property is particularly well-suited for families seeking a comfortable living environment near Lisbon, ensuring a steady demand. The combination of spacious accommodations and a neighborhood rating of 77/100 enhances its appeal for family rentals, making it a prudent choice for landlords. Buy-and-hold As a potential buy-and-hold investment, this property offers the advantage of appreciation in a growing suburb, augmented by its current subvalorizada status. The favorable market indicators suggest that holding onto this property could yield significant returns as the Cascais area continues to develop. Not ideal for short-term vacation rental Despite its admirable features, this house is not suitable for short-term vacation rentals due to its suburban setting, which lacks the vibrant energy that tourists often seek. Additionally, the area may not offer the extensive amenities that vacationers typically desire, limiting potential profitability. Not ideal for student housing This property is not an optimal choice for student housing, as the suburban environment may not align with the lifestyle preferences of typical students. The proximity to Lisbon may enhance job opportunities, but it does not guarantee a reliable tenant base for student rentals. Not ideal for luxury market Although the property boasts ample space, the overall suburban context and the housing condition rating suggests it does not cater well to the luxury market. The appeal lies more in family and long-term rentals rather than high-end clientele seeking exclusive properties.
Potential Economic Volatility The economic stability score of 80/100 suggests potential fluctuations in the local market, which could impact rental income and property value over time.
