Long-term rental The 4-bed chalet in Algueirão-Mem Martins, listed at €1,050,000, presents a significant gap of 22.1% above its fair value of €860,009, indicating that the property is overpriced. With a gross yield of only 2.1%, this investment lacks the return potential typically sought in long-term rental strategies. Family rental While the property boasts ample space, its ownership cost of €1,050,000, which is 22.1% above the estimated fair value, suggests it is overpriced for a family rental market. The yield of 2.1% does not sufficiently attract family tenants who generally seek more favorable financial terms in suburban areas. Buy-and-hold The current listing price of €1,050,000, which exceeds fair value by 22.1%, suggests that holding this property could lead to long-term financial strain due to its overpriced status. Furthermore, a gross yield of 2.1% reflects limited return potential, making it less appealing for a buy-and-hold investment strategy in the long run.
[Tenant turnover risk] With a Tenant stability score of 65/100, there is a significant risk of high tenant turnover, potentially leading to increased vacancy rates and associated costs.
