Long-term rental With a gross yield of only 1.7%, this property is unlikely to offer attractive returns for long-term rental investors, given its significant gap from fair value. The current market dynamics suggest that the property is overpriced at €640,000, which is 76.8% above the fair value of €148,676. Family rental Although the neighborhood scores a moderate 68/100 for its amenities, the excessive price of €640,000 poses a barrier for families seeking rental options. The property is overpriced by 76.8% relative to its fair value, leading to concerns about its long-term competitiveness in the family rental market. Buy-and-hold Investors considering a buy-and-hold strategy should be cautious, as the property is significantly overpriced at €640,000, given that it is valued at just €148,676. With a fair value gap of 76.8%, anticipated property appreciation may not justify the high entry price in the current market environment.
Tenant turnover risk The tenant stability score of 60/100 indicates a potential for higher turnover rates, which could lead to increased vacancy periods and costs associated with finding and onboarding new tenants.
