Long-term rental The property is overpriced at €770,000 compared to its fair value of €362,003, representing a 53.0% gap that significantly undermines its attractiveness for long-term rental. With a gross yield of only 2.9%, the investment fails to offer a favorable return in a suburban area like São João das Lampas e Terrugem. Family rental Given the high asking price of €770,000 versus a fair value of €362,003, the property does not align with the financial expectations of family renters in the region. The low yield of 2.9% further indicates that it may not be a practical choice for families looking for affordable housing options. Buy-and-hold Investing in this property for a buy-and-hold strategy is not advisable as it is overpriced at €770,000, while fair value stands significantly lower at €362,003. The gross yield of 2.9% suggests that long-term capital appreciation would be hindered due to the inflated purchase price, making it an unappealing option for investors looking for sustainable growth.
Tenant turnover risk: With both economic and tenant stability scores at 65/100, there is a heightened risk of tenant turnover, potentially leading to increased vacancy rates and lost rental income.
