Long-term rental This property is overpriced at €1,535,000 compared to its fair value of €1,201,630, reflecting a significant gap of 27.7%. With a gross yield of only 3.1% and a neighborhood rating of 58/100, it is unlikely to attract long-term tenants effectively. Family rental Despite its size and potential, this 5-bed house in Santo Isidoro is priced too high, limiting its attractiveness for the family rental market at €1,535,000 versus a fair value of €1,201,630. The 76/100 condition rating may appeal to some families, but the high purchase price and low yield of 3.1% render it a less desirable investment. Not ideal for student housing The property is priced at €1,535,000, well above the fair value of €1,201,630, with a significant discrepancy of 27.7%. Given its location in a rural area with a neighborhood rating of only 58/100, it is unlikely to attract student renters effectively. Not ideal for luxury market Priced at €1,535,000, the property overshoots its fair value of €1,201,630 by a substantial 27.7%, making it unsuitable for the luxury market. With a modest gross yield of 3.1% and average neighborhood qualities, it does not meet the expectations of high-end buyers.
Economic Vulnerability Economic stability is rated at 55/100, indicating potential volatility in market conditions that could impact rental income. Tenant Instability With a tenant stability score of only 60/100, there may be higher turnover rates, leading to increased vacancy periods and associated costs.
