Who this is for

Is this the service you need?

You’re buying to rent out, not to live in — and you want to see the spreadsheet before the photos.

You’re considering two or three properties and need a neutral advisor to compare them on numbers.

You want to understand net yield, not gross yield — with tax, vacancy, and management factored in.

Pains resolved

What you stop worrying about.

Falling for a listing because of the photos.

Gross-yield numbers that ignore every cost of ownership.

Authority

Why Sarah, specifically, for this.

Costa Larga was built around one discipline: no purchase without a model. Absorbed into Sarah Katerina, it keeps that rigour and pairs it with the tax and legal engine in the same office.

FAQ

Quick answers.

Do you find the property for me?

+

We don’t act as buyer’s agent. We review properties you or your agent surface, and we source through our network when the brief calls for it.

What do I get at the end?

+

A written investment memo per property: numbers, risks, exit scenarios, recommendation.

Does this include short-term rental feasibility?

+

Yes. Licence feasibility and projected STR yield, in coordination with VITA Host.
