rua Manuel Francisco Serra, 9E
Area baseline €306,878 + condition -€18,322 + location +€29,460 = modelled fair value of €318,016 (€2,224/m²), a €68,984 (17.8%) gap versus the €387,000 asking price.
Family rental The 3-bed duplex in União das Freguesias do Cacém e São Marcos, listed at €387,000, is overpriced compared to its fair value of €318,016, suggesting limited potential for family rental income at the current price point. With a gross yield of only 4.1% and a neighborhood rating of 74/100, this investment may struggle to attract long-term tenants seeking affordable family housing. Long-term rental Given its pricing, long-term rental potential for this property appears subdued since it is valued 17.8% above fair value, limiting margin for rental growth. The modest gross yield of 4.1%, combined with a condition rating of 67/100, reflects the challenges in achieving appealing returns for long-term rental investors. Buy-and-hold In a buy-and-hold strategy, the 3-bed duplex is not a compelling investment due to its overpriced status, which could hinder capital appreciation over time. With a fair value significantly lower than the listing price and the yield insufficient to justify a prolonged holding, this property may not fulfill long-term investor expectations.
[Economic downturn risk] Given the economic stability score of 80/100, a severe economic downturn could still impact rental income, especially with a tenant stability score of only 70/100, indicating potential volatility in tenant retention.
