Long-term rental The property offers a strong potential for long-term rental income, with a gap of 25.4% below fair value suggesting upside for investors. The gross yield of 4% is attractive, especially considering the favourable suburban Lisbon location that enhances tenant demand. Buy-and-hold This investment strategy is solid due to the property being significantly subvalued at €675,000 in comparison to its fair value of €846,305. With a decent condition rating of 56/100, the duplex is a resilient choice in a neighbourhood with a strong economic backdrop and solid amenities. Family rental The property is strategically located to attract families seeking residential space, given the suburban environment and access to Lisbon's amenities. Its subvalued price point allows for a compelling entry into a market with stable tenant quality and demand for family-friendly housing.
Tenant turnover risk: With a tenant stability score of only 65/100, there is a heightened risk of frequent tenant turnover, which may lead to increased vacancy rates and associated costs.
