Long-term rental The 4-bed duplex in Ericeira is currently overpriced, with a listing price that exceeds the fair value by 40.2%, suggesting that the potential for rental income does not justify the investment. The area's moderate access to amenities and employment opportunities further diminishes its attractiveness for long-term tenants, making this strategy less appealing. Family rental While the property could be suited for family rental, its current listing price of €697,500 is significantly above its fair value, indicating it may not attract budget-conscious families. Additionally, the neighbourhood's average tenant quality rating of 56/100 raises concerns about demand, suggesting that this investment strategy may yield disappointing results.
Economic Vulnerability The property faces potential instability due to a low economic stability score of 45/100, indicating a weak economic environment that may affect tenant retention and property value.
