Long-term rental The property is currently overpriced at €800,000, which is 40.4% above its fair value of €569,620, resulting in a gross yield of only 4%. Given the average condition score of 76/100 and the neighborhood score of 59/100, long-term rental potential is limited due to high costs and moderate appeal. Family rental With a current listing price of €800,000, this property is overpriced compared to its fair value of €569,620, leading to uncompetitive family rental yields of 4%. Although the proximity to Lisbon suggests liveability, the neighborhood's low score of 59/100 indicates that families may seek more appealing options. Short-term rental This property is overpriced at €800,000, which is 40.4% above the fair value of €569,620, making it non-viable for the short-term rental market due to fiscal constraints. The combination of a yielding score of only 4% alongside subpar neighborhood amenities renders it unattractive for prospective short-term vacationers. Student housing Priced at €800,000, which is significantly above its fair value of €569,620, this property is not an ideal candidate for student housing investment. The neighborhood's low appeal, highlighted by an overall score of 59/100, coupled with insufficient amenities, suggests that student occupancy would be challenging.
Low Economic and Tenant Stability The property faces a heightened risk due to its economic stability score of 50/100 and tenant stability score of 58/100, indicating potential difficulty in maintaining consistent rental income.
