Long-term rental The property in Santo Isidoro, listed at €695,000, is overshooting its fair value of €441,098 by 36.5%, indicating that it is overpriced for potential investors. With a gross yield of only 3.7% and a neighbourhood rating of 61/100, its long-term rental appeal is diminished in a limited local economy. Family rental With a current listing of €695,000, the property is overpriced as it significantly exceeds the fair value of €441,098 by 36.5%. Its condition rating of 67/100, coupled with the lack of strong amenities in the area, suggests challenges in attracting family renters at this high price point. Buy-and-hold The buy-and-hold strategy is less compelling for the property in Santo Isidoro, priced at €695,000—far above the fair valuation of €441,098, reflecting a 36.5% premium. Given the modest gross yield of 3.7% and the mixed ratings for the neighbourhood and condition, this investment faces potential depreciation risk in the long term.
Economic and Tenant Instability With both economic and tenant stability scores at 65/100, there is a heightened risk of fluctuations in rental income and occupancy rates, indicating potential challenges in maintaining steady cash flow.
