Long-term rental This property presents a significant gap of 33.5% between the listing price of €299,500 and its fair value of €199,026, indicating that it is overpriced. Additionally, the 0% gross yield reflects a lack of rental viability which may deter long-term tenants due to high costs relative to potential returns. Family rental Although families may seek larger spaces like this 4-bed apartment, the property’s current pricing at €299,500 exceeds its fair value of €199,026, marking it as overpriced. Furthermore, with a neighbourhood score of 63/100, potential renters might find better value in more reasonably priced options in the area. Buy-and-hold Investing in this buy-and-hold strategy is less appealing given the property’s listing price of €299,500, which is significantly above its fair value of €199,026, implying it is overpriced. The existing condition rating of 69/100 suggests that future maintenance costs could further diminish overall returns on investment in this scenario.
Economic Volatility Risk: With an economic stability score of 70/100 and tenant stability score of 60/100, there is a significant risk of tenant turnover and income fluctuations due to the moderate economic environment.
