Long-term rental The apartment is overpriced at €445,000 compared to the fair value of €233,408, indicating limited financial sense for holding in a long-term rental strategy. With a gross yield of only 3.3%, it does not justify the initial investment cost given the market conditions. Family rental At a listing price significantly above its fair value, this property is not a sound choice for a family rental strategy. The 3.3% gross yield suggests a lack of appeal to prospective tenants relative to pricing, especially in a suburban area with competitive rental alternatives. Buy-and-hold Considering the substantial gap between the listing price and fair value, investing in this property as a buy-and-hold strategy is not advisable. The property’s current condition and neighborhood scores do not substantiate its overpriced status, making it unlikely to yield long-term appreciation or positive cash flow.
Economic Vulnerability The economic stability score of 65/100 indicates potential vulnerabilities in the local market that could affect rental income and property value.
