Long-term rental The 3-bed duplex in Paranhos offers a gross yield of 3.6%, aligning with rental market expectations in suburban Porto. With a fair value of €567,089, the price of €518,000 suggests reasonable potential but does not present a significant opportunity for exceptional returns. Family rental This property features 211m² of living space in a safe suburban environment, ideal for families seeking a quality living arrangement. While the fair value indicates the pricing is reasonable, it may not attract families looking for standout value in a competitive rental market. Buy-and-hold Investing in this duplex may offer stability, given the property's decent condition rating of 78/100 and the neighborhood's overall quality. However, with a fair valuation at €567,089, the property’s pricing reflects standard market conditions rather than a significant growth opportunity for long-term appreciation.
Economic Vulnerability The economic stability score of 70/100 indicates a moderate risk to rental income, while the tenant stability score of 65/100 suggests a potential for higher turnover and vacancy rates.
