Long-term rental The property’s listing price of €450,000 is significantly higher than the fair value of €222,039, indicating that it is overpriced by 50.7%. While the 4.9% gross yield may seem attractive, it does not justify this pricing gap, making it a less viable option for long-term rental investments. Buy-and-hold Investing in this property as a buy-and-hold strategy appears unadvisable due to its overpricing at €450,000 compared to the fair value of €222,039, representing a 50.7% premium. The mediocre condition score of 56/100 further diminishes its potential for appreciation over time in the market. Family rental As a family rental property, this listing at €450,000 greatly exceeds the fair value of €222,039, highlighting the 50.7% disparity in pricing. The neighbourhood scores well on amenities and school quality; however, the high price point makes it less attractive for family-oriented tenants who often seek reasonable rental costs in desirable locations.
Tenant turnover risk With a tenant stability score of 70/100, there is a significant risk of potential turnover, which may lead to periods of vacancy and associated income loss.
