Long-term rental The potential for a long-term rental strategy is limited given that the property is priced at €310,000, which is significantly above the fair value of €248,450, leading to a potential rental yield of 0%. With a neighborhood rating of 62/100, attracting reliable tenants may prove challenging alongside the elevated price point. Buy-and-hold While the region benefits from proximity to Lisbon's employment opportunities, the high purchasing price suggests an unfavorable buy-and-hold scenario given the gap of 19.9% compared to fair value. Investors may face difficulties in achieving adequate returns on investment as current market conditions do not support the listed price. Family rental A family rental strategy does not capitalize on the property’s potential due to its overpriced status at €310,000, exceeding the fair value by nearly €62,000. Although the area has some amenities, the lack of rental yield at 0% and the current valuation warrant caution against investing for this demographic segment.
Tenant turnover risk The combination of a Tenant Stability score of 60/100 indicates potential issues with retaining tenants, which could lead to increased vacancy rates and rental income fluctuation.
