Long-term rental The property is overpriced at €2,100,000 compared to the fair value of €1,441,298, indicating a significant gap of 31.4%. With a yield of 0% gross, it is unlikely to provide a profitable return for long-term rentals. Buy-and-hold Despite the potential economic benefits from its location in the Lisbon suburbs, the property’s high listing price makes it an unattractive investment for a buy-and-hold strategy. The anticipated appreciation does not justify the 31.4% premium over fair value, suggesting a weaker long-term investment outlook. Family rental The property does not align with family rental objectives due to its overpriced nature at €2,100,000, particularly when considering its 0% gross yield. Families may prefer options that provide better value, making this property less appealing in a competitive rental market.
Tenant turnover risk The tenant stability score of 75/100 indicates a moderate risk of tenant turnover, potentially affecting consistent rental income.
