rua Campo Joaquim Santos Crispim, 5
Area baseline €693,158 + condition +€19,683 + location +€38,817 = modelled fair value of €751,658 (€2,327/m²), a €998,342 (57.0%) gap versus the €1,750,000 asking price.
Long-term rental Given the house's gross yield of 1.4%, it suggests limited profitability for long-term rental investors, especially compared to its fair value of €751,658. This significant 57.0% gap from fair value underscores that the property is overpriced, leading to diminished returns for landlords. Family rental While the property may appeal to family renters due to its spacious layout, the overpriced listing creates a substantial barrier for potential tenants, limiting marketability. With a fair value gap of 57.0%, families seeking rental options in this suburban area may find better alternatives at more reasonable prices. Buy-and-hold Investing in a buy-and-hold strategy is less advisable for this property given its current valuation of €1,750,000 compared to a fair value of €751,658. The 57.0% overpricing suggests long-term value appreciation is unlikely, therefore reducing the desirability for long-term investment strategies.
Economic Vulnerability The property faces potential financial instability due to an economic stability score of only 65/100, indicating heightened sensitivity to market fluctuations.
