Long-term rental The penthouse's gross yield of 3.1% combined with a fair value of €906,318 indicates that it could generate consistent rental income over time. However, with a property condition rating of 77/100, there may be some maintenance required to appeal to potential long-term renters. Family rental This property is situated in a family-friendly neighborhood with good schools, making it suitable for families seeking stability and quality of life. While it meets essential criteria for family rentals, the current price reflects a fair valuation, suggesting cautious consideration before proceeding. Buy-and-hold Given the proximity to Greater Lisbon and the steady demand for housing in Cascais, holding this property could yield benefits in the long run. Yet, with its fair price and moderate yield, a careful assessment of market trends will be essential for maximizing the investment's potential.
Risk of Tenant Turnover The tenant stability score of 65/100 indicates a higher likelihood of tenant turnover, which could adversely affect rental income and increase vacancy rates.
