Long-term rental The property offers a fair market value at €630,000, slightly above the fair value of €613,325, indicating it is appropriately priced. With a gross yield of 0%, it is essential to consider potential long-term appreciation rather than immediate cash flow. Family rental Given the property’s fair valuation and the surrounding suburban amenities typical of Greater Lisbon, it could serve as a stable family rental. However, the current yield of 0% suggests that investors may need to prioritize quality tenants for potential long-term returns. Buy-and-hold Acquiring this duplex at the current listing price aligns with a buy-and-hold strategy, as it’s fairly priced against its assessed value. This strategy would focus on appreciating property value over time, rather than significant cash flow in the short term, given the yield is at 0%.
Moderate Economic and Tenant Risk: With both economic stability and tenant stability scores at 70/100, there is a moderate risk that fluctuations in the market or tenant turnover could impact rental income stability.
