Long-term rental The apartment's current pricing strategy places it 41.1% above its fair value, suggesting a significant risk for long-term rental stability. Given the neighborhood's average tenant quality rating of 71/100, it may prove challenging to attract tenants at this elevated price point. Family rental While the apartment's spacious layout may appeal to families, its overpriced listing at €850,000 creates a financial barrier that could limit potential occupancy. The satisfactory condition rating of 83/100 highlights livability but is unlikely to offset the effects of the overpriced market. Buy-and-hold Investing in this property as a buy-and-hold strategy appears risky, given its considerable gap from fair value, indicating overpricing at €850,000. The location benefits from proximity to Lisbon and quality schools, but the 4.2% gross yield may not justify the investment against current pricing realities.
Economic downturn risk A drop in economic stability from 75 to below 70 could negatively affect tenant retention, leading to increased vacancy rates in the property.
