3-bedroom, 4-bathroom house of 292 m², energy rating C. Located on rua Engenheiro Carlos Santos, Rio de Mouro parish, Sintra municipality, Lisbon district.

The valuation. The asking price of €2,250,000 is significantly higher than the fair value of €663,542, representing an overvaluation of €1,586,458 (70.5%). This property does not represent a financially sound investment option. Buy-to-flip angle. A buy-and-flip strategy may not be viable given the high asking price compared to fair value, limiting potential profit margins on a quick resale. This property is unlikely to attract significant appreciation in the short term. Buy-to-let angle. With a gross yield of 1.2% and estimated rental income of €2,250/month, the rental strategy may provide stable cash flow, but the low yield indicates that it might not meet investor return expectations in a competitive market.
Fair value modelled at €663,542 from the area baseline, adjusted for condition and location. Asking €2,250,000 sits €1,586,458 (70.5%) above — overpriced versus fair value.

Family rental The current listing price of €2,250,000 is overvalued compared to the fair value of €663,542, resulting in a significant 70.5% gap. Additionally, the low yield of 1.2% and moderate neighborhood rating of 71/100 suggest that this property does not present an attractive option for family rentals. Long-term rental With a fair value of €663,542 and an asking price that exceeds this by 70.5%, the property demonstrates a concerning overvaluation. The 1.2% gross yield further indicates that long-term rental potential is low, making this investment less appealing. Buy-and-hold The property's significant gap from its fair value at €663,542 and the current listing price of €2,250,000 indicate that it is overpriced, jeopardizing potential capital appreciation. Coupled with a modest 84/100 condition score, the buy-and-hold strategy is not recommended for this property due to limited upside potential.
Economic sensitivity With both Economic Stability and Tenant Stability scores at 70/100, there is a moderate risk of fluctuating market conditions affecting rental income and occupancy rates.
