Long-term rental The property is overpriced at €2,600,000, significantly above its fair value of €1,223,439, creating a substantial gap that suggests limited long-term rental viability. With a gross yield of only 2.1%, this investment does not align with typical return expectations for long-term rentals in the area. Family rental Priced at €2,600,000, this property fails to present a competitive option for family rentals given its fair value of €1,223,439, which highlights the risk associated with such an investment. The gross yield of 2.1% indicates that families seeking rental accommodations may find more attractive alternatives in the Cascais e Estoril market. Buy-and-hold The current pricing of €2,600,000 significantly exceeds its fair value of €1,223,439, suggesting that long-term buying potential is compromised in this case. An unattractive gross yield of 2.1% further demonstrates that holding this property may not yield the expected financial benefits over time.
Tenant turnover risk The tenant stability score of 70/100 indicates a moderate likelihood of tenant turnover, which could lead to increased vacancy rates and associated costs.**
