Long-term rental The property is overpriced at €10,000,000, with a fair value of only €3,282,539, presenting a 67.2% gap that raises concerns about rental yield potential. At a gross yield of just 1.5%, the financial outlook for long-term rental strategies is not favorable given the market dynamics in Cascais e Estoril. Buy-and-hold Investing in this property as a buy-and-hold strategy appears unwise due to its significant overvaluation and the 67.2% gap to fair value. Additionally, with a low gross yield of 1.5%, the returns do not justify the ownership costs and ongoing investment in such a property. Family rental This property is overpriced, making it unsuitable for family rental strategies, especially considering its high listing price compared to the fair value of €3,282,539. Families seeking housing typically aim for affordability and value, which this property fails to deliver due to the steep 67.2% premium.
Tenant turnover risk High tenant turnover is likely given the low tenant stability score of 58/100, which could lead to increased vacancy periods and potentially higher leasing costs.
