Long-term rental The property's price of €2,100,000 is 36.2% higher than the fair value of €1,339,222, indicating that it is significantly overpriced for a long-term rental strategy. With a gross yield of 3.4% in a suburban area that scores only 60/100 for neighborhood quality, the financial returns may not justify the initial investment. Buy-and-hold At €2,100,000, the 4-bed penthouse is considerably overpriced compared to its fair value of €1,339,222, leading to a less favorable outlook for long-term appreciation. Given the condition rating of 80/100 and the economic stability linked to its proximity to Lisbon, potential investors may find the high entry price difficult to justify while waiting for future value growth.
Economic Sensitivity The property has a moderate economic stability score of 60/100, indicating potential vulnerability to economic downturns that could impact rental income and tenant retention.
