Long-term rental This property is overpriced at €2,250,000, well beyond its fair value of €676,056, resulting in a significant 70.0% gap. With a meager yield of 1.4%, the potential return on investment for long-term renting does not justify the acquisition cost. Buy-and-hold At €2,250,000, this property exceeds its fair value by 70.0%, reflecting an overpriced situation that may hinder capital appreciation over time. Given the solid condition rating of 83/100, while attractive, it is overshadowed by the poor investment outlook relative to its excessive price. Family rental Despite being in a reasonably rated neighborhood (77/100) and having good amenities due to its location near Lisbon, this property’s price of €2,250,000 is disproportionately high compared to its fair value of €676,056. Families may appreciate the space and condition, but the low yield of 1.4% makes it a risky endeavor for a family rental investment.
Economic downturn risk A slight decline in economic conditions could impact both the economic stability score of 80 and tenant stability score of 80, leading to potential vacancy increases and reduced rental income.
