Long-term rental The property is overpriced with a fair value gap of 53.9%, making it a less attractive option for long-term rental investments. At a gross yield of only 1.7%, the returns do not justify the current asking price. Family rental Given its high price relative to fair value, this penthouse is not a suitable choice for family rental strategies. The low yield of 1.7% suggests that potential returns won't align with the elevated purchase cost. Buy-and-hold Investing in this property as a buy-and-hold strategy is unadvised due to its significant overpricing of 53.9% against fair value. The combination of low yield and high cost limits the potential for capital appreciation over time.
Tenant turnover risk With both economic and tenant stability scores at 70/100, there is a heightened risk of tenant turnover, potentially leading to increased vacancy rates and loss of rental income.
