Long-term rental The property is substantially overpriced at €11,500,000 compared to a fair value of €3,006,152, indicating a 73.9% gap. With a low gross yield of only 1.1%, this investment is unlikely to provide a sustainable return through long-term rental. Family rental Despite the villa's sizable space and high condition rating of 90/100, its valuation of €11,500,000 is significantly above the fair value of €3,006,152. Families seeking rentals in the area may be put off by the high cost relative to the economic context and competing rental options. Value-add renovation While the property boasts solid condition and a decent neighborhood score of 77/100, its listing price of €11,500,000 greatly exceeds the fair value of €3,006,152. Any renovation efforts would not justify the current high price tag, as the investment is already overpriced by nearly 74% relative to its market potential.
Economic Dependence Risk The property is reliant on a moderately stable economic environment (75/100), which could signify vulnerability to downturns that may impact tenant retention and rental income.**
