Long-term rental Given the significant gap of 46.1% between the listing price and fair value, the 1-bed apartment in Alfena is overpriced, posing challenges for long-term rental profitability. The gross yield of 3.5% does not adequately compensate for the overvaluation in a suburban setting close to Porto. Family rental The property’s price point of €230,000 makes it less attractive for family rentals, especially when considering it is overpriced compared to its fair value. With a neighborhood rating of 69/100, potential tenants may seek better value options elsewhere. Buy-and-hold Investing in this property as a buy-and-hold strategy appears risky due to its overvaluation at €230,000, significantly above the fair value of €123,959. The modest gross yield of 3.5% may not provide adequate returns to justify holding this asset in the long run.
Economic and Tenant Risk The economic and tenant stability scores are both at 70/100, indicating a moderate risk of fluctuations in rental income or tenant turnover that could impact cash flow stability.
