This discrepancy suggests that the property is overpriced in the current market. Buy-to-flip angle.

Long-term rental The 3-bed apartment in Rio de Mouro has a fair value of €169,318, indicating that at a listing price of €245,000, it is overpriced by 30.9%. With a gross yield of 5.4%, this property may struggle to attract tenants given its relatively low condition score of 45 out of 100. Family rental While the apartment is situated in a suburb with access to Lisbon city center, the overpriced listing of €245,000 against a fair value of €169,318 diminishes its appeal for family renters. The condition score of 45 suggests that additional investments may be necessary to make it family-friendly, potentially offsetting rental yield benefits. Buy-and-hold Investing in this apartment as a buy-and-hold strategy is questionable, given its valuation of €245,000 compared to a fair value of €169,318, pointing to an overpricing situation. The average condition of 45 out of 100 may lead to increased maintenance costs over time, further complicating a long-term investment outlook.
Economic and Tenant Instability Risk With both economic stability and tenant stability scores at 70/100, there is a potential risk of fluctuations in rental income and occupancy rates that could impact overall investment returns.
