Long-term rental The 5-bed house in Santo Isidoro, Mafra is priced at €498,000, which is significantly above its fair value of €294,162, indicating a 69.3% gap. With a gross yield of 5.4% and a neighbourhood score of 58/100, the investment potential appears limited given the context of a rural area with constrained tenant quality and demand. Family rental Even though the property has potential for family rental, its current listing price of €498,000 does not align with its fair value of €294,162, signalling a 69.3% overpricing. The house's condition rating of 68/100 coupled with a rural setting suggests that attracting families seeking affordable long-term housing may present challenges. Not ideal for student housing This property is not suitable for student housing, as evidenced by its overvalued price of €498,000 against a fair value of €294,162, revealing a significant 69.3% gap. Furthermore, the rural context offers limited amenities typically sought by students, negatively impacting demand and rental performance. Not ideal for luxury market Listing at €498,000 while only justifying a fair value of €294,162 indicates that the property is indeed overpriced by 69.3%, making it unsuitable for the luxury market. The modest condition rating of 68/100 and lack of urban amenities further detract from its appeal to high-end buyers or renters.
Economic and Tenant Instability Risk: The property is exposed to potential instability with an economic score of 50/100 and a tenant stability score of 60/100, indicating a challenging market that may affect rental income and property value.
