Long-term rental The 3-bed apartment in Agualva e Mira-Sintra is currently overpriced at €279,700, significantly exceeding the fair value of €168,037 by 39.9%. Despite its decent gross yield of 4.2%, the high acquisition cost undermines long-term investment potential in a suburban location with a moderate neighborhood rating of 66/100. Family rental Although the property's condition score of 83/100 suggests that it is in good shape for tenants, the listing price of €279,700 is considerably above the fair value of €168,037. With a gross yield of only 4.2%, investing at this price does not align with the best interests of a family rental strategy, given that the neighborhood has moderate amenities and safety. Buy-and-hold The current ask price of €279,700 for this apartment makes it a poor candidate for a buy-and-hold investment, especially when compared to the fair value of €168,037 and a significant market gap of 39.9%. While the property boasts a relatively good condition, the high price diminishes long-term growth potential in a neighborhood rated only 66/100. Not ideal for luxury market Given the overpriced status at €279,700, this property is clearly not positioned for the luxury market segment where premium pricing would typically apply. The surrounding amenities and neighborhood rating further indicate a mismatch with luxury positioning, making this investment impractical. Not ideal for short-term rental The apartment's current price of €279,700 does not support a viable short-term rental strategy, especially given the fair value of €168,037. With a gross yield of 4.2%, the financial projections fall short, inhibiting its attractiveness for the short-term rental market.
Economic Sensitivity The economic stability score of 70/100 indicates a moderate risk of market fluctuations affecting tenant demand, while the tenant stability score of 60/100 suggests potential for higher vacancy rates.
