rua Planeta Mercúrio S / N
Area baseline €168,385 + condition -€35,859 + location +€19,533 = modelled fair value of €152,058 (€1,789/m²), a €187,942 (55.3%) gap versus the €340,000 asking price.
Long-term rental The property is overpriced at €340,000 compared to its fair value of €152,058, indicating a gap of 55.3%. With a gross yield of only 3.7%, the investment does not align with desirable long-term rental returns. Family rental Although the neighbourhood holds a strong score of 79/100, the property’s condition rating of 48/100 suggests high maintenance costs. Given its overpriced status, prospective family rental investors may find better value elsewhere. Buy-and-hold Even with the favorable access to Lisbon's job market, the significant gap between listing price and fair value makes this property a questionable buy-and-hold investment. Holding an overpriced asset may lead to diminished returns and increased vacancy risks over time.
Potential Tenant Turnover Risk The tenant stability score of 70/100 indicates a likelihood of higher turnover, which could lead to increased vacancy rates and associated costs over time.
