Long-term rental The 1-bed apartment in Queluz e Belas presents an attractive opportunity for long-term rental, given its fair value assessment that indicates it is subvalued by 26.7%. With a solid neighbourhood score of 75/100 and decent transit connectivity, this property is well-positioned to attract stable tenants. Family rental This spacious 190m² apartment is ideal for family rental due to its size and the good amenities associated with the area. Priced at €239,900, it offers a significant gap against its fair value, potentially making it a favorable choice for families seeking a comfortable living environment in a secure suburb of Lisbon. Buy-and-hold The buy-and-hold strategy aligns well with this property, particularly as its current price of €239,900 is considerably lower than the estimated fair value. With a neighbourhood rating of 75/100 and promising long-term rental prospects, this investment could appreciate substantially over time. Short-term rental This property is not suitable for short-term rental given its size and the surrounding competition in the market. Its current valuation does not align with typical short-term rental yields and may not attract transient guests effectively. Luxury market The apartment does not meet the luxury market standards, as its condition rating of 60/100 reflects an average quality that could deter high-end buyers or renters. Therefore, this property is not positioned to cater to the luxury segment, limiting its potential in that regard.
Economic Vulnerability The economic stability score of 80/100 indicates a potential risk due to fluctuations in the local economy affecting tenant retention and rental income stability.
