Long-term rental While the property is located in a highly-rated neighborhood with good commuting links, its current price of €303,000 reflects an overvaluation compared to the fair value of €192,671. With a gross yield of only 3.3%, this investment does not demonstrate sufficient return potential for a long-term rental strategy. Family rental This apartment, set in a commuter-friendly suburb near Sintra, may appeal to families due to its decent local amenities and quality of tenant profile in the area. However, its current listing price significantly exceeds the fair market value, indicating it is overpriced and might not attract families looking for value. Buy-and-hold Investing in this property as a buy-and-hold asset is not advisable, as it stands overvalued at €303,000 compared to a fair valuation of €192,671. The low gross yield of 3.3% further underscores the limited profitability of holding this property long term, given its overpriced status.
Economic Vulnerability With an economic stability score of 80/100, there remains a moderate risk of economic downturns affecting property value and rental income stability. Tenant Turnover Risk A tenant stability score of 75/100 indicates potential challenges with tenant retention, which could lead to increased vacancy periods and higher re-letting costs.
