Long-term rental The property’s listing price of €369,000 is 19.3% above the fair value of €297,720, indicating that it is overpriced. With a gross yield of 4.6%, the expected returns are diminished due to the elevated entry cost, making long-term rental less appealing. Family rental Although the property is well-suited for families given its size, the high asking price of €369,000 exceeds the fair value of €297,720 by 19.3%, highlighting its overpriced status. Additionally, the average condition rating of 62/100 may deter families seeking well-maintained spaces. Buy-and-hold The listing price of €369,000 is significantly above the fair value of €297,720, revealing that the property is overpriced for a buy-and-hold strategy. Investors should be cautious, as the 4.6% gross yield may not justify the inflated purchase price in the long term.
Tenant Volatility Risk With a tenant stability score of only 62/100, there is a heightened risk of tenant turnover, which could impact consistent cash flow and increase vacancy costs.
