Long-term rental This property, with a listing price of €450,000, exceeds its fair value of €331,690, indicating it is overpriced by 26.3%. Given its gross yield of 4% and a decent condition score of 78/100, long-term rental might not align with the property's financial expectations. Family rental With a listing price that surpasses the fair value by 26.3%, this apartment is overpriced at €450,000 compared to the €331,690 fair market estimate. While it may appeal to families due to its size and condition, the financial viability for a family rental could be compromised by the inflated price. Buy-and-hold At a valuation of €450,000, which is 26.3% above its fair value of €331,690, this property is clearly overpriced for a buy-and-hold strategy. The potential returns might not justify the purchase price, particularly when considering the suburban location and the reliance on Lisbon's employment and amenities for tenant opportunities.
Economic Vulnerability The economic stability score of 55/100 indicates a high risk of market fluctuations that could adversely affect rental income.
