Long-term rental The 3-bed duplex in Algueirão-Mem Martins is currently priced at €450,000, which exceeds its fair value of €405,233 by 11.0%, indicating it is overpriced. With a gross yield of 3.8%, the investment appears unlikely to provide satisfactory returns in the long run. Family rental Despite being suitable for family rental markets, the property's listing price of €450,000 surpasses the fair value of €405,233, marking it as overpriced. The current condition score of 69/100 and neighborhood score of 67/100 suggest limited appeal to potential family tenants relative to its cost. Buy-and-hold The price of €450,000 for the duplex is above the fair value of €405,233, categorizing it as overpriced for a buy-and-hold strategy. Although the vicinity to Lisbon offers economic stability, the 3.8% yield may not justify the elevated investment cost over time.
Economic Vulnerability The economic stability score of 65 indicates potential susceptibility to market fluctuations, which could negatively impact rental income and property value over time.
