Long-term rental Given the property is overpriced with a listing price 6.6% above its fair value, potential long-term rental yields of 2.8% may not compensate for the initial investment cost. While the property’s location near Lisbon offers economic opportunities, the high price tag may deter prospective tenants seeking value. Buy-and-hold The property’s current valuation suggests it is overpriced, and holding onto an asset that yields only 2.8% gross returns could limit future financial growth. Although the local area provides suburban safety and amenity access, the investment does not align with typical growth expectations due to its excessive pricing. Family rental As a family rental, the property appears overpriced with a 6.6% gap from fair value, which may reduce its attractiveness to families seeking affordable housing options. Despite decent neighbourhood ratings and proximity to Lisbon, the high price may push potential family renters elsewhere for better value.
Tenant turnover risk The relatively low tenant stability score of 65/100 indicates a potential for higher tenant turnover, which can lead to increased vacancy rates and associated costs.
