Long-term rental The property at €860,000 is significantly overpriced, with a fair value of only €376,676, representing a gap of 56.2%. With a gross yield of 0%, investing in a long-term rental strategy is unlikely to provide sustainable returns in the current market conditions. Family rental While the house is situated in a suburban area with an average condition rating of 86/100, its valuation does not justify its current price tag, making it less favorable for family rental investments. The neighborhood quality score of 59/100 indicates that tenant demand may be limited, further exacerbating the financial challenges for this strategy.
Economic Vulnerability The low economic stability score of 50/100 suggests potential for economic downturns that could adversely affect rental income.
