Long-term rental The property at €490,000 is overpriced compared to its fair value of €425,085, representing a 13.2% gap. With a gross yield of only 3.1%, the investment may struggle to meet returns, making it less attractive for long-term rental strategies. Family rental Although the property is in a suburban area with access to city amenities, its listing price exceeds the fair value by 13.2%, suggesting it may not represent a solid family rental investment. The average condition score of 76/100 further indicates it might require additional maintenance, impacting long-term family rental desirability. Buy-and-hold Investing in this duplex as a buy-and-hold strategy is challenging due to its current price being above fair value by 13.2%, which could hinder capital appreciation potential. The lower gross yield of 3.1% adds to the concerns, as it may not provide sufficient income to justify the high acquisition cost.
Tenant Default Risk Given the Economic stability score of 65/100, there is an increased risk of tenant default, which may affect consistent income generation.
