Long-term rental The apartment's listing price of €259,000 is significantly above its fair value of €126,985, suggesting it is overpriced by 51.0%, which would hinder long-term rental profitability. Although the gross yield of 4.1% shows potential, its elevated price reduces the attractiveness of this investment strategy. Buy-and-hold Investing in this property for a buy-and-hold strategy is not advisable due to its 51.0% markup over fair value, which erodes potential returns over time. The apartment's condition score of 56/100 also indicates it may require significant maintenance, further impacting long-term value appreciation. Family rental While the location may appeal to families due to a mix of urban and suburban characteristics, the apartment's price being 51.0% higher than fair value makes it an overpriced investment. This premium could deter potential family tenants, limiting rental demand despite the neighborhood's decent score of 75/100.
Tenant turnover risk The tenant stability score of 70/100 indicates a moderate risk of tenant turnover, which may lead to potential vacancy periods and associated costs for the property owner.
