Long-term rental The property, listed at €870,000, is significantly overpriced compared to its fair value of €552,519, resulting in a 36.5% gap. With a gross yield of only 3.6%, it may not generate adequate returns for a long-term rental investment given the elevated price point. Family rental While the suburban location near Greater Lisbon offers good transport links, the €870,000 listing price places this property well above its fair value of €552,519, indicating it is overpriced by 36.5%. As a family rental, this property may struggle to attract tenants when other more fairly priced options are available in the market. Buy-and-hold The buy-and-hold strategy is undermined by the property’s inflated price of €870,000, which exceeds its estimated fair value of €552,519 by 36.5%. Investors may find that the current gross yield of 3.6% fails to justify such a high initial investment in a property that is overpriced. Not ideal for Given the high price and low yield, this property is not ideal for student housing, short-term vacation rental, or the luxury market, as these segments typically require better valuation metrics to ensure profitability. The 71/100 condition score and 70/100 neighborhood rating further emphasize the risk of investing in an overpriced asset in these categories.
Economic and Tenant Stability Risk With both economic stability and tenant stability scoring 70/100, there is a moderate risk that unforeseen economic fluctuations could impact tenant retention and rental income stability, potentially leading to increased vacancy rates or decreased cash flow amidst a changing market.
