Long-term rental The property offers a gross yield of 5.4%, which aligns well with the rental demand in Lisbon's highly desirable Santos António neighborhood. However, its condition rating of 61/100 suggests that some renovation may be needed to maximize long-term rental appeal. Short-term vacation rental With Lisbon's popularity as a tourist destination, this duplex could benefit from short-term vacation rentals, capitalizing on the area's strong amenities and public transport access. Nevertheless, the 7.4% gap from fair value indicates a need for careful consideration regarding overall investment costs. Buy-and-hold The stable demand for housing in Lisbon's center positions this property well for a buy-and-hold strategy, especially with its favorable neighborhood rating of 88/100. While the investment is currently assessed at fair value, ongoing evaluation of the market conditions is advised to ensure sustained profitability.
Tenant turnover risk The tenant stability score of 80/100 indicates a moderate level of risk for frequent tenant changes, which could affect rental income consistency.
