Family rental This 1-bed apartment in Algueirão-Mem Martins, listed at €290,000, is overpriced compared to its fair value of €215,305, with a significant gap of 34.7%. While it is located in a suburb with access to Lisbon, the gross yield of 3.3% does not justify the high asking price for family rental purposes. Long-term rental With a fair value of €215,305 and a listing price of €290,000, this property represents a considerable risk for long-term rental investors due to the 34.7% price gap. Although the area enjoys relative safety and a decent neighborhood rating of 73/100, the yield of 3.3% and overall condition rating of 67/100 suggest that this investment is not optimal given its current pricing. Buy-and-hold The 1-bed apartment's listing price of €290,000 results in it being significantly overvalued against a fair value assessment of €215,305, indicating a 34.7% markup. As a buy-and-hold investment, the low gross yield of 3.3% and mediocre condition score do not present a compelling case for future appreciation under these circumstances.
Economic Vulnerability The economic stability score of 80/100 suggests a generally stable environment, but the tenant stability score of 70/100 indicates potential risks in tenant retention that could affect rental income.
