avenida Manuel Júlio Carvalho e Costa
Area baseline €1,494,598 + condition +€37,750 + location +€113,589 = modelled fair value of €1,645,937 (€5,450/m²), a €4,154,063 (71.6%) gap versus the €5,800,000 asking price.
Long-term rental The property presents a gross yield of only 1.6%, indicating that it is unlikely to meet long-term financial returns acceptable for investors in the rental market. Given the significant gap of 71.6% from its fair value of €1,645,937, it suggests that this property is overpriced for a long-term rental strategy. Buy-and-hold While the location near Lisbon offers economic stability, the current asking price of €5,800,000 does not reflect the fair value of the property, which may hinder potential appreciation. Owning a property that is overpriced by 71.6% challenges the feasibility of this buy-and-hold investment approach. Family rental The property is in a suburban setting which usually attracts families, yet its gross yield of 1.6% indicates limited rental income potential. With a fair value significantly lower than the listing price, this family rental strategy may not yield the expected financial benefits given the property is overpriced.
Tenant turnover risk: With a tenant stability score of 55/100, there is a heightened risk of high tenant turnover, which could lead to increased vacancy periods and costs associated with finding new tenants.
