Long-term rental The 4-bed apartment in Cascais is overpriced at €1,590,000 compared to a fair value of €1,010,279, resulting in a significant 36.5% gap. With a low yield of 2.3%, this investment will struggle to generate adequate cash flow over time, making long-term rental an unattractive strategy. Short-term vacation rental This property, despite its coastal location and appealing features, is overpriced at €1,590,000, significantly exceeding the fair value of €1,010,279. The high price combined with the 2.3% gross yield diminishes the potential for short-term vacation rental profitability, suggesting that this market strategy would be less viable. Luxury market While the apartment has attributes suitable for the luxury market, its asking price of €1,590,000 does not align with the fair value of €1,010,279, indicating it is overpriced by 36.5%. The combination of an 82/100 condition rating and a 78/100 neighbourhood score suggests it may not appeal to high-end buyers given its inflated price point and cannot sustain a luxury positioning effectively.
Tenant turnover risk The tenant stability score of 75/100 suggests a moderate risk of turnover, which could lead to potential vacancy periods and loss of rental income.
