Long-term rental The property, listed at €2,700,000, is overpriced by 55.5% compared to its fair value of €1,201,570, resulting in a low gross yield of 1.9%. With a neighbourhood score of 76/100, the area may appeal to long-term tenants but the high initial investment is not supported by adequate rental returns. Family rental At a listing price of €2,700,000, this property is overpriced by 55.5% compared to its fair value of €1,201,570, leading to diminished financial viability for family rentals with a yield of just 1.9%. While the apartment's condition is rated 86/100, the hefty investment may deter potential family renters seeking value for money. Buy-and-hold The buy-and-hold strategy is not advisable for this property priced at €2,700,000, which is 55.5% above its fair value of €1,201,570, and offers a mere gross yield of 1.9%. Investors may find that the projected long-term appreciation does not justify the overvaluation, making this a risky commitment for sustained investment.
Potential Economic Downturn The property has a high economic stability score of 85/100, but any sudden decline in this score could negatively impact rental demand and tenant turnover, especially with a tenant stability score of 75/100 indicating some vulnerability.
