Investing now could yield considerable returns as the neighborhood continues to develop and attract quality tenants. Not ideal for short-term rental, student housing, luxury market This property doesn’t fit the short-term rental model due to its structure and location dynamics, which favor long-term stability over transient accommodations. Additionally, it lacks the luxury appeal needed to attract high-end tourists, making it less suitable for the luxury rental market.
Tenant turnover risk The tenant stability score of 65/100 indicates a potential for higher tenant turnover, which can lead to increased vacancy rates and loss of rental income over time.
