Long-term rental With a fair value of €3,430,361, this property is currently underpriced at €1,997,500, presenting a significant opportunity for long-term rental strategies. The absence of gross yield might be offset by potential capital appreciation given the favorable neighborhood characteristics. Family rental The strong neighborhood attributes, particularly in safety and schools, make the 3-bed duplex appealing for family rentals in the Algés area. Given its underpriced status and spacious layout, it offers an attractive living option that aligns well with the needs of families. Buy-and-hold Investing in this 3-bed duplex for a buy-and-hold strategy is supported by its current undervaluation, suggesting strong future returns. Additionally, the mixed urban-suburban location in Oeiras offers sustained demand due to its proximity to Lisbon and favorable living conditions. Not ideal for Positioned above current market dynamics, this property is not appropriate for luxury market strategies due to its marketplace perception. Also, its zero gross yield and location factors limit its viability as a short-term vacation rental or student housing investment.
Economic Downturn Risk The combination of a 75/100 economic stability score and a 70/100 tenant stability score suggests a potential vulnerability to economic downturns, which may lead to decreased rental income or increased vacancies during unfavorable conditions.
