Long-term rental The property is priced at €1,300,000, which is 45.6% above its fair value of €707,222, indicating a significant risk for long-term investment in this market. With a gross yield of only 2%, the return does not justify the premium asking price, making it an unattractive option for long-term rental. Family rental Given the property’s high listing price of €1,300,000, which exceeds the fair value by 45.6%, prospective family renters may be deterred by the elevated cost compared to what they can find in the area. Additionally, with a neighbourhood rating of 58/100, the appeal for family rentals is further diminished despite reasonable property conditions. Buy-and-hold The asking price of €1,300,000 significantly exceeds the fair value of €707,222, highlighting a poor buy-and-hold opportunity in the current market context. The low yield of 2% suggests that holding the property for appreciation might not yield favorable financial returns, particularly with a neighbourhood score of 58/100. Not ideal for: This property is unsuitable for student housing, given its high price point and relatively low neighbourhood rating. It also does not fit the luxury market segment or short-term vacation rental strategies due to its elevated price compared to prevailing values in the area.
Tenant turnover risk With a tenant stability score of 60/100, there is a notable risk of increased tenant turnover, potentially leading to higher vacancy rates and associated costs.
