Long-term rental The 3-bed duplex in São João das Lampas e Terrugem is priced at €415,000, which is 10.7% above its fair value of €370,493, indicating it is overpriced. With a gross yield of 0%, this property does not present a compelling long-term rental investment opportunity. Family rental Although the property is located near Greater Lisbon, the €415,000 listing price exceeds the fair market value by 10.7%, which reflects its overpriced status. The current condition score of 76/100 suggests the property may require additional investment for family-friendly improvements, detracting from its rental appeal. Buy-and-hold At €415,000, the duplex is overpriced compared to its fair value of €370,493, creating a potential barrier for buy-and-hold investors looking for long-term appreciation. Given the lack of yield and the current condition, holding this asset may not result in favorable returns or capital growth over time.
Economic and Tenant Instability Risk: With both economic and tenant stability scores at 70/100, there is a moderate risk of fluctuations that could lead to decreased rental income and higher vacancy rates.
