Long-term rental The current pricing of €2,100,000 represents a significant gap above the fair value of €1,892,000, indicating the property is overpriced in this strategy. With a low yield of 1.8%, this investment may not provide adequate return relative to its cost. Family rental Given the neighborhood score of 63/100, it may draw families, but the property’s listing price at €2,100,000 is well above the fair value of €1,892,000, marking it as overpriced. The limited yield of 1.8% further suggests this asset may not attract the desired tenant pool for family rentals. Buy-and-hold The strategy to buy and hold is challenged by the property being overpriced at €2,100,000 against its fair value of €1,892,000, leading to an 11.0% gap. Additionally, the gross yield of only 1.8% indicates that this property may not deliver a strong return on investment over the long term.
Tenant turnover risk: With a tenant stability score of 60/100, there is a significant risk of tenant turnover, which could lead to increased vacancy rates and higher costs associated with finding new tenants.
