Long-term rental The current listing price of €440,000 exceeds the estimated fair value of €390,812, positioning this property as overpriced by 11.2%. With a gross yield of only 4.2%, the long-term rental strategy may not provide adequate returns given the market pricing. Buy-and-hold Investing in this 3-bed duplex at €440,000 reflects an opportunity cost, as it is overpriced compared to the fair value of €390,812 by 11.2%. The long-term potential of the area may be appealing, but the current price limits upside appreciation and overall investment viability. Family rental At a listing price of €440,000, this property stands 11.2% above its fair value of €390,812, suggesting an overpriced market entry for a family rental. Given the property’s decent condition rating of 75/100, it may appeal to families, yet the high price could deter interest in a competitive rental market.
Economic Vulnerability The property's economic stability score of 80/100, while strong, indicates potential sensitivity to downturns, as a score below 85 may reflect underlying market instabilities that could impact tenant retention and rental income. Tenant Reliance With a tenant stability score of 75/100, there is a notable risk of turnover and vacancy that could disrupt cash flow, potentially leading to increased costs associated with re-leasing the property.
