Long-term rental With a fair value of €202,229, the property at €299,500 is overpriced by 32.5%, indicating limited potential for yielding favorable returns in the long term. Moreover, the gross yield of 0% reflects the lack of rental income viability, especially in a neighbourhood with only a moderate rating of 70/100. Family rental Although the proximity to Lisbon suggests access to better employment and schools, the apartment’s condition score of 68/100 and the overall overvaluation make it less attractive for family rentals. Families seeking high-quality living may find better options than a property priced significantly above its fair value, which could deter potential tenants. Buy-and-hold Investing in this property with an asking price of €299,500 would mean holding an asset that is overpriced by 32.5%, thus limiting long-term capital appreciation opportunities. With a fair value at €202,229, the potential for significant returns is compromised, particularly given the moderately rated neighbourhood and zero gross yield.
Tenant turnover risk With a tenant stability score of 60/100, there is a heightened risk of frequent tenant turnover, which can lead to increased vacancy rates and associated costs.
