No. Most of our work is done remotely — structured calls, shared documents, and detailed written reports. We conduct property visits, due diligence and contractor meetings on your behalf in Portugal. You travel when it matters: typically once, for the deed signing.
A traditional estate agent is paid by the seller — their incentive is to close a transaction, not necessarily to protect your interests. SISO works on the side of whoever hires us, with a single point of accountability coordinating every step, from the first data point to handover.
We coordinate with your lawyer and tax adviser — we do not replace them. We explain the Portuguese purchase process in plain English, flag items that need legal attention, and ensure nothing is missed. Monique Nogueira — law graduate in Brazil (OAB-active) with 25+ years of experience in strategic litigation and corporate compliance — coordinates this process and maintains a trusted network of English-speaking solicitors, lawyers and tax specialists in Portugal whom we recommend to clients when needed.
Send us a brief introduction: your situation, timeline, budget range and what you are trying to achieve. We will review it and come back within 2 business days with an honest assessment of whether and how we can help — before any commitment on either side.

"We had a vision for our family — and a great deal of uncertainty about how to get there. SISO turned that uncertainty into a plan. Four weeks later, we had floor plans, photographs, and a clear map of every renovation phase. For anyone managing works in a country they are still getting to know, that peace of mind is priceless."
"We moved from São Paulo to Portugal with two children and our dog. SISO was with us from the very first moment: real INE data, a structured visit programme, independent technical analysis, and full coordination with our lawyer through to the deed. We never felt alone — and that feeling, in a move of this magnitude, is everything."
"When we found the property that felt right, we needed someone who would tell us the truth — not what we wanted to hear. Carlos delivered a rigorous inspection: full photo report, geo-statistical analysis, and a clear, data-based recommendation. We moved forward with total confidence. There are decisions in life where you simply cannot afford to get it wrong."
"We arrived in Portugal with two young children and the feeling of starting from scratch. Carlos analysed the market region by region with data we could never have found on our own. But what truly moved us was walking into our new home and finding it ready — everything prepared for our first family dinner. Today, when our children say that Portugal is their home, we always remember that first day."
