Long-term rental The property’s listing price of €665,000 reflects a significant gap of 31.4% from its fair value of €456,228, indicating an overpriced situation. With a gross yield of only 3.6%, the long-term rental strategy does not present a compelling investment opportunity given the current pricing. Family rental At €665,000, this property is overpriced compared to its fair value of €456,228, which may limit the appeal for family rentals in the suburban neighborhood of Ericeira. Despite decent local amenities, the expected rental returns are not justified by the listing price, making this strategy less attractive. Buy-and-hold Considering the property’s overpriced status, with a fair value of €456,228 compared to its listing of €665,000, the buy-and-hold strategy is hindered by potential equity erosion. The 3.6% yield fails to provide sufficient compensation for the entry cost, making long-term appreciation less likely in this suburban market.
Economic and Tenant Instability Risk: With an economic stability score of 55 and a tenant stability score of 60, there is a significant risk of fluctuating rental income and potential vacancies that could impact profitability.
