Santo Isidoro, Mafra, Lisbon
Area baseline €766,647 + condition +€48,375 + location +€21,466 = modelled fair value of €836,488 (€2,161/m²), a €13,512 (1.6%) gap versus the €850,000 asking price.
Long-term rental The property is overpriced by 1.6%, making it a less favorable option for long-term rental investors seeking value. With a modest gross yield of 3.8% and a neighbourhood score of 57/100, potential returns may be hampered as demand could be limited in this rural area. Buy-and-hold Given that the property is valued at 1.6% above its fair market value, the buy-and-hold strategy may not yield expected returns. The combination of a decent condition score of 84/100 and a lackluster neighbourhood rating suggests that long-term appreciation may stagnate. Family rental While the property potentially suits the family rental market, its 1.6% overpricing raises concerns about rental competitiveness. Additionally, the neighbourhood's low score of 57/100 indicates potential challenges in attracting families looking for desirable local amenities and employment opportunities.
Economic Vulnerability The property has a low economic stability score of 55/100, indicating potential susceptibility to economic downturns that could affect rental income and property value.
