rua São Tomé e Príncipe
Area baseline €831,432 + condition +€9,188 + location +€69,840 = modelled fair value of €910,460 (€5,419/m²), a €339,540 (27.2%) gap versus the €1,250,000 asking price.
Long-term rental The property is overpriced by 27.2% against its fair value of €910,460, resulting in a less attractive gross yield of 3.5%. With a condition rating of 79/100 and a neighbourhood score of 71/100, it may not offer competitive advantages for long-term tenants. Buy-and-hold Maintaining this asset as a buy-and-hold investment is not ideal due to its 27.2% premium over fair value, which could hinder potential appreciation. Given the relatively low yield of 3.5%, there is limited incentive to invest for the long term under current market conditions. Family rental While a family rental strategy may seem viable, the property remains overpriced by 27.2% and offers a yield of only 3.5%. The high listing price may restrict the quality tenant pool in an already competitive housing market. Short-term vacation rental This property is not ideal for a short-term vacation rental strategy, given its significant overvaluation of 27.2%. The current pricing does not align with the yield expectations typically required for short-term rental success.
Economic and Tenant Instability Risk The combined scores of 75 for economic stability and 70 for tenant stability indicate a moderate risk of fluctuating income streams, which may impact overall property performance and profitability.
