Long-term rental This 4-bed duplex in Algueirão-Mem Martins presents a fair value assessment relative to its listing price, making it a stable choice for a long-term rental strategy. However, with a 0% gross yield, potential investors should carefully consider the cash flow implications of this property. Buy-and-hold While the property holds a fair valuation within the Greater Lisbon area, prospective buy-and-hold investors should be aware of its lack of immediate rental yield. Given the solid condition (90/100) and the reasonable neighborhood score (73/100), it could serve as a durable asset in a diversified portfolio over time. Family rental The property is well-suited for family rental, given its spacious design and favorable condition, despite the fair market gap of 8.7%. Families may appreciate the suburban safety and decent educational options available in the area, although they should be informed of the competitive rental market dynamics.
[Tenant turnover risk] With a tenant stability score of 65/100, there is a significant risk of higher tenant turnover, potentially leading to increased vacancy rates and loss of rental income.
