About Sarah

Twenty years inside the system. Now on your side.

I spent two decades at SUMA — Spain's regional tax authority — handling the files that foreign buyers only hear about when something goes wrong. This practice exists so you never have to be one of those files.

My story

Why I left.

Twenty years of reviewing other people’s paperwork taught me two things. First, the Spanish property system works — but only for those who understand its logic. Second, foreign buyers almost never do, and most of the advisors they meet don’t either.

I kept watching the same avoidable mistakes: Modelo 210 filed late, ITP miscalculated, plusvalía contested years later, purchase vehicles chosen without a minute of tax planning.

At some point the answer stopped being “work harder inside the system” and became “build the advisory that should have existed on the other side of the counter.”

What makes this different

Three things you won’t find anywhere else on the coast.

The rules, from the inside.

Twenty years enforcing them means I know which ones bend, which ones don't, and where the unwritten conventions live.

Zero commissions from the sell side.

No agent, developer, or bank pays me a referral fee. The fee you see is the only income from your file.

One workflow, every line.

Purchase, tax, investment, management — coordinated under one roof. No handoffs between three advisors who've never met.

How I work

Four working principles.

Clarity before speed.

If you don't understand the next step, we don't take it.

Numbers on paper.

Every estimate, fee, tax exposure in writing before you commit.

One point of contact.

You write to me. I coordinate the rest.

No surprises at the notary.

By the time you sign, everything has been reviewed twice.

The group

Sarah Katerina, Costa Larga, VITA Host — one team, one roof.

The practice grew into a group because a property journey has three distinct chapters — and handing a client to a stranger at each one made no sense. Elsa and a trusted network of collaborators handle the volume.
