Long-term rental The property is overpriced at €797,000 compared to its fair value of €758,278, resulting in a gap of 4.9%. A gross yield of 2.9% indicates that the investment may not provide the expected returns over the long term. Buy-and-hold Given the property's current valuation position, holding onto this asset for an extended period could lead to lower-than-anticipated capital appreciation. The 85/100 condition rating is favorable, yet the 60/100 neighborhood rating raises concerns about future demand and performance. Family rental This property may attract family renters due to its size and suburban location, but its overpriced status could limit profitability. The existing gross yield of 2.9% reflects potential challenges in achieving strong rental income relative to investment costs.
Economic Sensitivity Risk The property is at risk due to its moderate economic stability score of 65/100, which indicates vulnerability to economic downturns that could impact overall tenant demand and rental income stability. Tenant Volatility Risk With a tenant stability score of 60/100, there is a concern for potential turnover and vacancies, which may lead to fluctuating rental income and additional costs associated with finding new tenants.
