Long-term rental The 4-bed duplex in Barcarena, listed at €590,000, presents a significant opportunity with a fair value of €967,674, indicating it is underpriced by 64.0%. The stable neighborhood conditions and solid tenant quality also suggest that this property could attract long-term renters looking for spacious accommodations. Family rental With a good condition rating of 75/100, this duplex is well-suited for family rental, particularly given its size of 259m² and the services available in the Oeiras area. The proximity to amenities and suburban characteristics will make it appealing to families seeking a comfortable living environment, capitalizing on the notable 64.0% disparity from fair value. Buy-and-hold Investing in this property as a buy-and-hold strategy is promising, as its current listing reflects a substantial undervaluation compared to its fair value of €967,674. This suggests potential for significant appreciation over time, particularly in a stable suburban market that supports long-term growth prospects.
Economic Vulnerability The economic stability score of 75 suggests moderate risk; a downturn could affect tenant demand, while the tenant stability score of 70 indicates potential for increased vacancy rates.
