The valuation. The asking price of €189,000 significantly exceeds the fair value of €44,811 by €144,189, indicating that the property is overpriced by 76.3%.

With a gross yield of 8% estimated at €1,260 per month, this investment in Oliveira do Douro could generate steady rental income over time. The property targets long-term family rentals but may struggle due to its dated condition.

Long-term rental The property is overpriced at €189,000 compared to a fair value of €44,811, creating a significant gap of 76.3%. With a gross yield of 8%, the returns do not justify the initial investment due to its inflated cost. Buy-and-hold Given that the purchase price is excessively high at €189,000, it is unlikely that this property will gain sufficient value over time to offset the current disparity from its fair value of €44,811. The poor condition rating of 30/100 further implies that the costs of ownership will not align with market expectations in the long term. Family rental Although the property is located in a suburban area of Porto with urban amenities, its listing price of €189,000 is substantially above the fair value of €44,811, indicating it is overpriced. Families seeking long-term rentals may be dissuaded by both the high purchase cost and the property's condition, rated at just 30/100.
Tenant turnover risk With a tenant stability score of 60/100, there is a heightened risk of tenant turnover, which could lead to increased vacancy rates and associated costs.
