Several factors influence real estate prices in Sintra (Santa Maria e São Miguel), notably its location, historical significance, and amenities. The picturesque landscape and proximity to natural parks, such as the Sintra-Cascais Natural Park, attract buyers seeking a blend of nature and urban living, driving demand and prices upwards. The area is known for its enchanting palaces and historical monuments, such as the Pena Palace and Quinta da Regaleira, which add a unique charm that appeals to both local and international buyers. Additionally, the availability of schools, healthcare facilities, and shopping centers can significantly affect property values. For example, properties near the Colégio de Santa Maria or other reputable schools might command higher prices due to their desirability among families. The ease of access to Lisbon via the Sintra train line also plays a role; homes closer to the train station often see increased demand, thus impacting their market value.
