Short-term vacation rental The 0-bed apartment building in Santa Maria Maior, listed at €1,340,000, presents a substantial gap of 88.5% against its fair value of €153,573, indicating a significant overvaluation. The lack of yield and the high listing price make it an unsuitable investment for short-term vacation rental strategies. Long-term rental Given the property’s current listing price and a projected yield of 0%, it is clear that the €1,340,000 valuation is excessively high compared to its fair value. As such, pursuing a long-term rental strategy would not be advisable due to the considerable financial gap. Buy-and-hold Investing in the 0-bed apartment building for a buy-and-hold strategy would be impractical at the asking price of €1,340,000, which is significantly above its fair value of €153,573. This drastic overpricing deters potential appreciation and undermines the viability of holding this property long-term.
Tenant turnover risk The tenant stability score of 70/100 indicates a moderate risk of tenant turnover, which could lead to increased vacancy rates and potential revenue loss.
