Maria Isabel Mansour

I am Maria Isabel Mansour, a verified real estate agent with ZOME Cascais, serving clients in and around Sintra and Cascais. My journey into real estate began after a 40-year career in banking, where I held senior management roles focused on commercial and property management.

This experience, paired with an MBA from Henley Management College, taught me the value of precision, negotiation, and understanding client needs-skills I now channel into every property transaction. When I joined the real estate sector in 2017, I knew I wanted to work with a company that shared my priorities: integrity, rigorous training, and measurable results.

The birth of ZOME in 2019, through the merger of two trusted brands, solidified that alignment.

“I think about you first” isn’t just a tagline-it’s how I approach every client. My banking background honed my ability to analyze markets and manage complex deals, but it’s my local expertise in Sintra and Cascais that allows me to connect people with the right opportunities.

Whether you’re buying your first home, renting a vacation property, or exploring international investments, I prioritize clarity and peace of mind. For foreign buyers, that means guiding you through legal nuances and cultural adjustments without overwhelming jargon.

For sellers, it means leveraging ZOME’s extensive network to reach the right audience efficiently.

My work focuses on three pillars

Residential Sales, Historic Properties, and Luxury Properties. Sintra, a UNESCO World Heritage site, and Cascais, with its blend of coastal charm and upscale living, demand a tailored approach. Historic homes (imóveis antigos) require balancing preservation with modernization, while luxury properties (palacetes or villas with sea views) demand discretion and an understanding of high-end market expectations. I’ve been part of ZOME’s Topliner program since 2019 because I stay committed to results without compromising the transparency clients deserve.

FAQ Q: Do you specialize in helping foreign buyers? Yes. My international experience and fluency in English and Portuguese enable me to support foreign clients in navigating the local market, from paperwork to understanding regional nuances.

Q: Can you help with properties outside Sintra and Cascais? While my primary focus is these two areas, I collaborate with ZOME’s Iberian-wide network to assist with referrals, ensuring clients receive consistent service quality even beyond my immediate region.

Q: How do you market historic properties? I highlight their unique character-like traditional architecture or heritage status-while addressing practical needs, such as renovation guidance or connecting with preservation experts.

Working with me isn’t just about transactions; it’s about building relationships that endure long after keys are handed over. I measure success by how well I’ve listened-and how seamlessly I’ve turned that into action.
