Long-term rental This property, listed at €665,000, significantly exceeds its fair value of €369,630, resulting in an overpriced status. Given the gross yield of 4.4%, the investment potential is diminished by the excessive initial cost and moderate suburban demand in the area. Family rental While the property offers adequate space for a family, its overpriced listing at €665,000 compared to the fair value of €369,630 makes it a less attractive investment opportunity. The neighborhood score of 58/100 indicates limited appeal for families, further complicating the potential for successful long-term rentals.
Economic and Tenant Instability With an economic stability score of 55/100 and a tenant stability score of 60/100, the property may face challenges in attracting and retaining reliable tenants, potentially leading to increased vacancy rates and reduced rental income.
