Long-term rental The property is overpriced by 33.0% compared to its fair value, indicating it may not generate attractive returns for long-term rental investors. The yield of 4.8% gross in conjunction with a condition score of 55/100 suggests potential maintenance costs that could further reduce profitability. Family rental With a fair value of €160,903, the asking price of €240,000 presents a significant gap that detracts from its appeal as a family rental. The neighborhood rating of 67/100 indicates moderate desirability, but the high purchase price may limit affordability for many potential family tenants. Buy-and-hold Investing in this property as a buy-and-hold strategy is challenged by its overpriced status, which undermines future capital appreciation potential. The condition score of 55/100 coupled with the 33.0% gap from fair value could lead to difficulties in achieving long-term investment goals.
Economic and Tenant Stability Risk The current economic stability score of 65/100 suggests a moderately unstable market, which when combined with the tenant stability score of 65/100 indicates a heightened risk of tenant turnover and vacancy rates affecting rental income stability.
