Long-term rental The property in Cascais e Estoril, listed at €4,200,000, is overpriced by 17.6% compared to its fair value of €3,460,137, leading to a gross rental yield of only 2.9%. Given its mediocre condition rating of 70/100 and the neighbourhood's score of 66/100, long-term rental prospects appear limited and less attractive. Family rental With its high asking price and a fair value gap of 17.6%, the property is not a feasible option for family rental, which generally seeks reasonable market pricing. The house's yield of 2.9% and average neighbourhood ratings suggest that it may not meet the expectations of families looking for value in a location that is already competitive. Buy-and-hold The buy-and-hold strategy for this house is challenged by its 17.6% overpricing relative to fair value, which diminishes potential long-term growth in equity. With a low gross yield of 2.9% and a neighbourhood rating of only 66/100, the investment could face significant hurdles in achieving adequate returns over time.
Economic Vulnerability The economic stability score of 65/100 suggests a moderate risk of economic downturn impacting rental income and property value negatively.
