Long-term rental The 4-bed duplex in Santo António is reasonably priced at €1,990,000, reflecting a fair value gap of just 4.0%. With a gross yield of 1.8% and solid tenant quality, it offers stable long-term rental potential in a central Lisbon location. Short-term vacation rental Despite its fair valuation, the current market conditions and yield of 1.8% may limit the attractiveness of this property for short-term vacation rentals. However, its desirable location and high quality could still provide moderate returns depending on management strategies. Buy-and-hold Acquiring this well-conditioned duplex at a fair price allows for a hold strategy that takes advantage of Lisbon's strong housing market. The enduring appeal of the neighbourhood reinforces the potential for appreciation over time, although the yield remains on the lower end at 1.8%. Not ideal for student housing Given the broader market dynamics and tenant quality, this property is not ideal for student housing. The target demographic may not align with the offering, leading to potential vacancy risks.
Potential Tenant Turnover The tenant stability score of 75/100 indicates a risk of potential turnover, suggesting that while the property is in a stable economic environment, there may still be fluctuations in tenant retention.
