Ericeira, Mafra, Lisbon
Area baseline €261,492 + condition -€3,506 + location -€4,184 = modelled fair value of €253,802 (€1,923/m²), a €265,198 (51.1%) gap versus the €519,000 asking price.
Long-term rental This property, despite being centrally located in Ericeira, presents a 51.1% gap from its fair value, signaling an overpriced scenario for long-term rental strategies. With a gross yield of 0% and a neighborhood quality rating of only 46/100, the potential for sustainable cash flow appears highly limited. Buy-and-hold Investing in this duplex as a buy-and-hold asset is fraught with risks, given its significant price overvaluation of €519,000 compared to the fair value of €253,802. The condition score of 73/100 is not compelling enough to justify such a premium in a market that is struggling with tenant quality and area amenities. Not ideal for: Short-term vacation rental and Luxury market.
High Vacancies Risk The low Economic stability score of 40/100 combined with a Tenant stability score of 50/100 indicates a significant risk of high vacancies, suggesting potential difficulties in maintaining stable rental income.
