Long-term rental Despite offering a reasonable gross yield of 3.4%, this property is overpriced at €450,000 compared to its fair value of €365,197, indicating a gap of 18.8%. The home's condition rating of 68/100 and neighborhood score of 63/100 suggest limited appeal to long-term tenants, which is essential for sustainable income. Family rental The 3-bed duplex is overpriced, making it less attractive for families seeking affordable housing in a suburban setting, especially when fair value estimates fall significantly below the asking price. Additionally, while the property provides suburban amenities, the combined ratings of 68 and 63 point to potential challenges in attracting family renters in a competitive market. Buy-and-hold At a listing price of €450,000, the property is overpriced and deviates notably from its fair value, which limits effective buy-and-hold investment strategies that rely on property appreciation. With a modest yield and subpar condition, the potential for capital growth is compromised, making this investment less appealing for long-term asset accumulation.
Tenant turnover risk The tenant stability score is 60/100, indicating a potential for higher tenant turnover, which could lead to increased vacancy rates and loss of rental income.
