Long-term rental The 3-bed duplex in São Domingos de Rana has a fair value of €444,097, indicating a significant 30.1% premium at the current listing price of €635,000. With a gross yield of only 3%, this property may not generate attractive returns for long-term rental investors given its overpriced status. Family rental While the neighborhood offers family-friendly amenities and proximity to Lisbon for employment, the €635,000 asking price greatly exceeds the fair value of €444,097, marking it as overpriced by 30.1%. The relatively low gross yield of 3% suggests that the investment may not fulfill the financial expectations for families seeking rental properties in the area. Buy-and-hold Investing in this duplex with a market price of €635,000, which is 30.1% above its fair value of €444,097, reflects an overpriced opportunity that may hinder long-term appreciation. Given the current gross yield of 3%, the potential for favorable returns on a buy-and-hold strategy seems diminutive, raising concerns about the overall investment viability. Not ideal for short-term vacation rental, luxury market, student housing Due to its high price point of €635,000—30.1% above the fair value of €444,097—this property does not align with any of these rental strategies, which require more competitive pricing to attract clientele. Its current offering lacks the yield and value proposition necessary for success in these markets.
Economic vulnerability With an economic stability score of 70, there is a risk that downturns in the local economy could significantly impact property values and rental income. Tenant turnover risk A tenant stability score of 75 indicates a potential but moderate risk of tenant turnover, which can affect consistent cash flow.
