Short-term vacation rental The property is overpriced at €580,000, with a fair value of only €436,116 reflecting a significant gap of 24.8%. This makes it an unfavorable choice for short-term vacation rentals, as the yield of 0% gross does not justify the investment. Buy-and-hold Despite the attractive location on the Algarve coast, the €580,000 listing significantly exceeds the fair value of €436,116, indicating that it may not appreciate adequately over time. The current yield of 0% gross further emphasizes the lack of immediate financial returns in a buy-and-hold strategy. Luxury market While the 4-bed duplex is positioned in a desirable neighborhood, its price of €580,000 far exceeds the fair value of €436,116, making it overpriced for the luxury market. The property’s sufficient condition score of 74/100 does not compensate for the lack of value, suggesting it may not attract high-end buyers seeking competitive pricing.
Economic Vulnerability The economic stability score of 60/100 indicates potential fluctuations in the market that could impact rental income.
