Family rental The property’s current listing price of €3,750,000 represents a 32.8% premium over its fair value, making it an overpriced option for family rentals. With a gross yield of only 1.9%, the financial return does not justify the investment in terms of family-oriented tenants seeking long-term stability. Long-term rental At €3,750,000, this property is overpriced by 32.8% compared to its fair value of €2,824,072, limiting its attractiveness for long-term rental purposes. The subpar yield of 1.9% further suggests that this investment may not provide adequate returns over time. Buy-and-hold The listing price of €3,750,000 is significantly above its fair value of €2,824,072, reflecting an overpriced situation for a buy-and-hold strategy. With a gross yield of just 1.9%, the potential for capital appreciation may not sufficiently compensate for the initial high investment cost.
Tenant turnover risk The tenant stability score of 60/100 indicates a higher likelihood of tenant turnover, which can lead to increased vacancy rates and associated costs.
