avenida de Sintra
Area baseline €1,413,992 + condition +€37,000 + location +€117,192 = modelled fair value of €1,619,096 (€5,470/m²), a €1,280,904 (44.2%) gap versus the €2,900,000 asking price.
Long-term rental The property in Cascais e Estoril is overpriced, with a gap of 44.2% compared to its fair value of €1,619,096, resulting in a low gross yield of only 1.9%. Given the high price point and moderate neighborhood rating of 70/100, it is unlikely to attract high-quality long-term tenants. Family rental While the large size of the house may appeal to families, the significant pricing above fair value makes it an unattractive option for family rental markets. The property’s gross yield of 1.9% indicates that potential rental income does not justify the investment at this elevated price. Buy-and-hold Although holding this property might seem advantageous due to its location near Lisbon, the 44.2% overvaluation currently places it at a significant financial risk. The combination of high acquisition costs and low yield suggests that this buy-and-hold strategy may not be financially sustainable in the long term.
Economic Dependence Risk The economic stability score of 70/100 indicates a moderate risk of economic downturn which could affect tenant retention and rental income.
