Long-term rental The property is currently listed at €1,375,000, which is 12.7% above its fair value of €1,220,283, indicating it may not provide adequate returns for long-term rental investments. With a gross yield of 4.1%, the property fails to meet the investment criteria for optimal long-term rental performance. Family rental Listed at €1,375,000, the property exceeds its fair value by 12.7%, making it a less attractive option for family rentals that typically prioritize value for money. The area’s decent condition rating of 79/100 may not justify the elevated price tag for families seeking affordable long-term housing. Buy-and-hold At a listing price of €1,375,000, this property is overpriced compared to its fair value of €1,220,283, which could diminish potential appreciation over time. A gross yield of 4.1% further indicates that investors may not achieve significant returns through a buy-and-hold strategy given the current asking price.
Economic and Tenant Instability The combined economic and tenant stability scores of 70/100 indicate potential volatility that may lead to decreased cash flow or difficulty in maintaining occupancy rates.
