Long-term rental This 4-bed penthouse in Avenidas Novas is positioned to benefit from a strategic long-term rental approach, given its central location in Lisbon with a high neighbourhood rating of 90/100. With a gross yield of 3.4%, the property represents an opportunity to provide steady rental income while taking advantage of market dynamics that justify its listing price of €1,480,000, which is 14.2% below fair value. Buy-and-hold Investors employing a buy-and-hold strategy can view this property as an attractive option, leveraging the appreciation potential tied to its fair value of €1,724,810. With 85/100 condition and cultural significance in the area, the property is well-positioned for long-term capital appreciation despite a current market price suggesting it is subvalued. Short-term vacation rental The penthouse's location in the vibrant Avenidas Novas area makes it a strong candidate for a short-term vacation rental strategy, capitalizing on Lisbon's tourism appeal. With a market listing notably below its fair value, this property could yield attractive returns while maintaining a competitive edge in the short-term rental space due to its high condition and neighbourhood ratings. Not ideal for: Family rental The penthouse may not be the best fit for family rentals as its design and market dynamics cater more effectively to a transient demographic interested in the cultural and economic offerings of Lisbon. Although it's priced below its fair market value, the unique features may not align with the needs of family-oriented tenants.
Low Tenant Turnover Risk The tenant stability score of 85/100 suggests a relatively high chance of turnover that could result in increased vacancy and associated costs.
