The gross yield of 3.8% is attractive for long-term renters seeking stable housing in a suburban area of Greater Lisbon, close to employment opportunities. Buy-and-hold Investing in this property allows for capital appreciation potential as it is currently underpriced, offering a fair value gap of 19.3%. The strong location in Porto Salvo combined with the gradual market growth in Greater Lisbon makes this property a suitable candidate for a buy-and-hold investment strategy. Family rental At €398,000, this duplex is underpriced relative to its fair value of €474,779, making it a feasible option for families looking for a comfortable suburban environment. The decent condition and neighborhood scores of 71/100 suggest that this property will meet the needs of families seeking quality housing close to Lisbon. Not ideal for short-term rental Although the property is underpriced, its current gross yield of 3.8% and neighborhood characteristics do not favor a short-term rental strategy. The suburban setting may not attract the transient clientele typical for short-term rentals. Not ideal for luxury market This duplex, while underpriced, does not fit into the luxury market segment due to its suburban context and average condition score of 71/100. Therefore, it is less suitable for buyers seeking high-end properties. Not ideal for student housing Although priced attractively, the property is underpriced relative to its fair value, which does not make it an ideal option for student housing. The suburban location may not cater to the preferences often sought after by students attending Lisbon's universities.
Economic and Tenant Instability Risk: With both the economic stability and tenant stability scores at 70/100, there is a moderate risk of fluctuating rental income due to potential market or tenant turnover instability.
