Long-term rental The property is overpriced by 32.9% compared to its fair value, which diminishes its attractiveness for long-term rental strategies. The gross yield of 2.4% does not justify investing in a property with a condition rating of 56/100 in a moderately safe suburban area. Family rental With a significant gap from the fair value, the property presents challenges for family rental markets, where price sensitivity is often higher. The attractive neighbourhood rating of 76/100 cannot compensate for the overpriced listing and low yield of 2.4%. Buy-and-hold Investing in this property for a buy-and-hold strategy is not advisable given its 32.9% overpricing against fair value. Although the vicinity to Lisbon and decent neighbourhood score offers appeal, the low yield and average property condition present substantial risk for long-term appreciation.
Economic Vulnerability With an economic stability score of 75, the property may be exposed to market fluctuations that could affect rental income and occupancy rates significantly.
