rua Fonte das Lágrimas
Area baseline €797,280 + condition -€103,125 + location +€1,902 = modelled fair value of €374,217 (€1,559/m²), a €200,783 (34.9%) gap versus the €575,000 asking price.
Long-term rental The property is overpriced with a fair value significantly lower than the listing price, leading to a potential yield of 5.5% gross that is not compelling in the current market. Given its condition score of 48/100 and moderate neighborhood attributes, long-term rental may struggle to attract quality tenants. Family rental While the listing price suggests the property could serve as a family rental, it is overpriced at €575,000, which may deter prospective renters looking for value. The local demand predominantly from locals and the neighborhood's lower-rated amenities indicate that family rental opportunities could be limited. Not ideal for short-term vacation rental The property is overpriced and therefore not suitable for the short-term vacation rental strategy, as the high listing price does not align with the typical budget of vacation renters. Additionally, the peripheral location and average neighborhood scores further diminish its appeal to this market segment. Not ideal for luxury market With the property being significantly overpriced at €575,000 against a fair value of €374,217, it is not positioned to attract the luxury market. The lack of high-end features and amenities, coupled with a condition and neighborhood rating below average, further dissuades luxury investments.
Economic and Tenant Instability With an economic stability score of 50/100 and a tenant stability score of 55/100, this property is at a high risk for unstable rental income due to potential fluctuations in the local economy and tenant retention issues.
