The valuation. The asking price of €13,500,000 is significantly above its fair value of €6,129,236, resulting in an overvaluation of €7,370,764 (120.3%). This property is not considered a financially sound investment based on current market conditions. Buy-to-flip angle. With an asking price well above fair value, a buy-and-flip strategy would not yield significant profits, as the market would resist high markup on resale. This strategy lacks viability given the current pricing structure. Buy-to-let angle. A rental income strategy is also challenged by the gross yield of only 1.1%, amounting to approximately €12,375/month. Given neighborhood dynamics and commuter trends, consistent long-term leasing may not meet investor expectations.

Long-term rental The property is overpriced at €13,500,000 compared to the fair value of €6,129,236, indicating a significant gap of 120.3%. With a gross yield of only 1.1%, it is unlikely to generate attractive long-term rental returns in this suburban Greater Lisbon context. Family rental At a listing price far exceeding its fair value, this property is not positioned well for family rental opportunities, particularly given the gap of 120.3%. The underwhelming yield of 1.1% further suggests that attracting families as long-term tenants may be challenging in the current market. Buy-and-hold As a buy-and-hold investment, this property’s considerable price overvaluation of 120.3% diminishes its appeal due to the limited potential for price appreciation. Coupled with a low gross yield of 1.1%, the investment does not seem to align with typical buy-and-hold strategies in stable suburban markets.
Economic Vulnerability The economic stability score of 65/100 suggests potential risks related to economic downturns, which could impact tenant retention and rental income.
