Long-term rental The property is overpriced at €2,600,000, representing a 52.1% gap from its fair value of €1,244,527, making it an unattractive option for long-term rental investment. With a gross yield of only 2.2%, investors are unlikely to achieve satisfactory returns in comparison to the market average. Family rental At a listing price of €2,600,000, this property is valued 52.1% above its fair market value of €1,244,527, which does not support its suitability for family rental strategies. The yield of 2.2% is insufficient to justify the high acquisition cost, leaving little potential for profitable family rental income. Buy-and-hold The property’s valuation at €2,600,000, which is 52.1% higher than the fair value of €1,244,527, indicates it is overpriced for a buy-and-hold investment strategy. The low gross yield of 2.2% diminishes the long-term capital growth prospects that investors typically seek in the buy-and-hold approach.
Tenant turnover risk The tenant stability score of 75/100 indicates a moderate likelihood of tenant turnover, which could impact the property's rental income stability.
