Long-term rental The property located in Arroios, Lisbon is overpriced at €715,000, significantly surpassing the fair value estimate of €95,836. With a gross yield of only 3%, it may not offer sufficient return on investment for long-term rental purposes. Short-term vacation rental Given its central location and acceptable condition rating of 78/100, the property could attract tourists, but its current list price of €715,000 indicates it is overpriced compared to a fair value of €95,836. The low gross yield of 3% raises concerns about the financial viability of this strategy. Buy-and-hold Investing in this property as a buy-and-hold strategy is not advisable, as the market price of €715,000 is 86.6% above the fair value of €95,836. This significant overpricing may hinder long-term appreciation potential and overall investment success.
Potential Economic Downturn One key risk is the threat of a potential economic downturn that could affect even stable economies, given a high economic stability score of 85/100, which indicates vulnerability if the market changes.
