Long-term rental The property is overpriced at €2,250,000, significantly exceeding its fair value of €624,996, resulting in a substantial gap of 72.2%. With a gross yield of only 1.1%, the long-term rental potential does not justify this high acquisition cost. Family rental While the property boasts a reasonable condition rating of 86/100 and is situated in a liveable suburban area, its pricing severely undermines the viability of family rental opportunities. The gap to fair value indicates that families would be paying a premium for housing that does not align with market standards. Buy-and-hold Investing in this property as a buy-and-hold strategy is not advisable due to its overvaluation of €2,250,000 compared to the fair value of €624,996. The low gross yield of 1.1% further suggests that holding this property will not yield satisfactory returns in the long run.
Tenant Turnover Risk The tenant stability score of 50/100 suggests a high risk of tenant turnover, which could lead to increased vacancy rates and associated costs when trying to fill the property again.
