Family rental The property in Malveira e São Miguel de Alcainça is overpriced, making it a less attractive option for families seeking long-term housing in a suburban area. With a gross yield of only 2.3%, the investment potential is limited, despite its family-friendly focus. Long-term rental Given its fair value of €544,654 and the listing price of €940,000, this property is not well-positioned for long-term rental investments. The neighborhood ratings indicate a decent area, but the significant price gap diminishes the financial appeal for landlords. Buy-and-hold Investing in this property as a buy-and-hold strategy is challenging due to its current valuation being 42.1% higher than fair value. While it lies within commuting distance to Lisbon, the high purchase price limits the potential for appreciation over time.
Moderate Economic and Tenant Risk: With both economic stability and tenant stability scores at 70/100, there is a substantial risk that market fluctuations or tenant turnover could negatively impact rental income and property value.
