Long-term rental Despite solid underlying metrics, this property is overpriced, with a fair value that exceeds the listing price by 5.5%. Its gross yield of 3.1% indicates limited returns, making it less attractive for long-term rental investment. Buy-and-hold While the property is situated in a suburban area with good transport links to Lisbon, the 5.5% gap to fair value suggests that it is overpriced. The expected returns for this strategy are diminished by the premium paid over the fair market value. Family rental The property is located in a neighborhood that scores 70/100, but its current listing price indicates that it is overpriced by 5.5%. Families seeking rental homes may find this option appealing; however, the high price may deter potential tenants from committing to rental contracts.
Tenant turnover risk The tenant stability score of 70/100 indicates a moderate risk of tenant turnover, which could lead to increased vacancy rates and additional costs associated with re-leasing the property.
