Located on rua Soto Maior, 33, Santa Maria e São Miguel, São Martinho e São Pedro de Penaferrim parish, Sintra municipality, Lisbon district.

The valuation. The asking price of €3,900,000 significantly exceeds the fair value of €1,049,095 by €2,850,905, representing a staggering 73.1% overpricing. Thus, this property is not a sound investment opportunity at its current listed price.
Fair value modelled at €1,049,095 from the area baseline, adjusted for condition and location. Asking €3,900,000 sits €2,850,905 (73.1%) above — overpriced versus fair value.

Area baseline €924,926 + condition +€53,875 + location +€70,294 = modelled fair value of €1,049,095 (€2,434/m²), a €2,850,905 (73.1%) gap versus the €3,900,000 asking price.
Long-term rental Given the 1.8% gross yield, this 5-bed palace in Sintra is unlikely to provide a satisfactory return on investment for long-term rental purposes, especially considering the significant gap from its fair value. The property’s condition rating of 84/100 does not justify its overpriced status, making it less attractive for rental stability. Family rental While the family-oriented community and moderate urban influences may appeal to renters, the property's €3,900,000 asking price is substantially above its fair value of €1,049,095. The high pricing diminishes the potential for a lucrative family rental strategy, given that the gross yield is only 1.8%. Buy-and-hold As an investment strategy, buy-and-hold becomes less feasible with this property given its current overpriced status at €3,900,000, far exceeding the fair valuation. The large gap in value, coupled with a suboptimal yield of 1.8%, indicates this asset may not appreciate to provide expected returns in the long run.
Tenant turnover risk High economic stability score of 70/100 suggests potential for fluctuations in local economic conditions that may impact tenant retention, despite a relatively strong tenant stability score of 75/100.
