Family rental This property, priced at €620,000, is situated in a suburban location within Greater Lisbon, making it a feasible option for families seeking access to Lisbon's job market. However, the neighborhood score of 63/100 suggests moderate amenities and housing quality, which indicates that family demand may be limited despite its fair valuation. Long-term rental With a gross yield of 3.8% and a fair value standing at €663,781, this property presents stable long-term rental potential in an area with job access. Nevertheless, the somewhat average neighborhood rating indicates that while it may attract tenants, the competition could be more favorable for other properties in better-rated areas. Buy-and-hold Currently valued at €620,000, this property holds investment appeal within the Algueirão-Mem Martins area as a buy-and-hold strategy, particularly given its proximity to Lisbon. The fair status of the property suggests it could appreciate over time, although the neighborhood's lower score may attract slower market growth compared to higher-rated regions.
Tenant turnover risk The combination of a Tenant stability score of 60/100 suggests a higher likelihood of tenant turnover, which could lead to increased vacancy rates and associated costs.
