Long-term rental The property’s gross yield of 3.3% is considered low, suggesting that the rental income will not adequately compensate for its high purchase price of €850,000. Given the fair value of €439,858, this investment is not advisable for long-term rental strategies. Buy-and-hold With the property priced at €850,000, significantly above its fair value of €439,858, the long-term appreciation potential appears limited. Investing in this asset with a yield of only 3.3% in a neighbourhood rated 58/100 may not provide the desired returns over time. Family rental Although the house features ample space, the high purchase price relative to its fair value makes it a problematic choice for family rental strategies. A gross yield of 3.3% and a neighbourhood rating of 58/100 indicate that this property may not attract families looking for value and quality living conditions.
Economic and Tenant Instability The combined scores of Economic stability at 60/100 and Tenant stability at 55/100 indicate a significant risk of fluctuating rental income and potential difficulties in securing long-term tenants.
