Long-term rental This property may generate stable long-term rental income given its proximity to Lisbon and suburban appeal, though a 0% yield indicates current rental pricing is low. Its condition rating of 71/100 suggests potential for minimal upkeep, making it a reasonable choice for steady occupancy. Buy-and-hold As a buy-and-hold investment, this duplex offers the potential for long-term appreciation within a family-friendly neighborhood, despite being priced fairly at €475,000. The minor 4.6% gap from fair value signals a gradual increase in property worth may occur as the market evolves. Family rental The 4-bed duplex meets the needs of families seeking suburban living near Lisbon, aligning with local suburban safety norms, although the lack of gross yield highlights a cautious investment outlook. While the property is positioned well for family renters, the neighborhood rating of 68/100 suggests competition exists, warranting strategic marketing to attract ideal tenants.
Tenant Turnover Risk With a tenant stability score of only 65/100, there is a heightened risk of tenant turnover, which may lead to increased vacancy rates and associated income loss.
