Monique and Carlos start from a simple conviction: anyone making a decision of this scale in Portugal deserves a rigorous method, real data, and a single point of accountability coordinating every step — from the first data point to final delivery.
The working principle is always the same: the outcome of whoever hires us — never the side of the transaction we're on. Questions about how we work in your case? Talk to us directly.
Every analysis starts from official sources: INE, Banco de Portugal, Municipal authorities. We don't work with portal estimates. Our clients receive verifiable information — not impressions.
Every engagement has defined phases, clear deliverables and objective decision criteria. We apply the same structure across all projects — from relocation to construction oversight — because rigour is not optional.
SISO is a small team — the work is always done by us, directly.

In December 2019, Carlos and Monique arrived in Porto with a few suitcases, two children — Duda, then sixteen, and Victor, six — and a decision made. They had not come to explore. They had come to stay.
And over the months that followed, navigating contracts, construction budgets, licences and the bureaucracy of a country they were still getting to know, they realised that something was missing: someone who could simultaneously handle market data, purchase strategy, technical construction management and the ability to see in a property what it could still become.
From analysis to finished project, from the first data point to the last detail — we work on the side of whoever hires us.
Our interest is that every client reaches the right decision for their life — with the right property, at a fair price and with no legal surprises, or, when that is the case, with the decision to wait, rent, or not move forward.
If you are thinking about starting over in Portugal — to live, to invest, or simply to find out if it makes sense — we are here. Just as we were for ourselves, that December afternoon in 2019.
