Family rental The asking price of €680,000 is significantly above the fair value of €406,254, indicating that this property is overpriced for family rental purposes. With a modest yield of 4.4% and average neighbourhood ratings, potential returns may not justify the investment. Long-term rental Given the pricing of €680,000 compared to a fair value of €406,254, this property is overpriced for a long-term rental strategy. The average condition and yield of 4.4% suggest that long-term returns may not be attractive enough for prospective investors. Buy-and-hold With the property priced at €680,000 and a fair value of €406,254, it is clear that it is overpriced for a buy-and-hold investment strategy. The resulting gap of 40.3% diminishes the likelihood of achieving satisfactory capital appreciation over time.
Tenant turnover risk With a tenant stability score of 65/100, there is a considerable risk of frequent tenant turnover, potentially leading to increased vacancy rates and higher costs associated with re-letting the property.
