I find the home you dream of in Spain, or an investment that fits your plan. Then I take care of everything else: the numbers, every tax, the paperwork. One person, on the buyer’s side from start to finish.
On the buyer’s side
My job is to check every step before you take it.
Buying in Spain involves many steps and many documents. I search the market to your brief and stay with you until the keys are in your hand. This is what you get.
Numbers before emotion
Before you make an offer I check the real price per m², the net yield, the costs and how easy the home will be to sell later. If the numbers don’t work, I tell you.
MARKET ANALYSISOnly the tax the law requires
ITP, IVA, plusvalía, Modelo 210, rental income. I spent two decades on the other side of the counter, so I know where foreign buyers lose money and check every relief you qualify for.
TAX EXPERTISEOne person, start to finish
NIE, bank account, checks, notary, keys and the years after. Your whole file sits in one place, with one person who explains every step in plain English.
PEACE OF MIND
Who I am
I’m Sarah Katerina.
For twenty years I was an office director at SUMA Gestión Tributaria, the public body that manages local taxes in the province of Alicante. I reviewed the paperwork of thousands of taxpayers, and it taught me two things.
01
The Spanish property and tax system works, but only for those who know its rules.
02
Foreign buyers almost never know them, and often neither do the people advising them.
I kept seeing the same avoidable mistakes: missed deadlines, miscalculated taxes, decisions taken without a plan. So I left the system to create a service built around the buyer.
Behind every file there is a person, a family and a life plan. That is what really matters.

★★★★★Google review
“Purchasing a property in Spain as a foreign buyer can be a complex and overwhelming experience, but working with Sarah Katerina was one of the best decisions we made. … She took the time to explain every detail, answered all of our questions with patience, and guided us through decisions that would have been very difficult to navigate on our own. … Even after the purchase, she has continued to support us with tax matters, property-related administration, and ongoing advice, giving us complete peace of mind.”Zanko D.Posted on Google, 2026
★★★★★Google review
“Honestly, at one point I was convinced it was all over and I would lose both my deposit and the apartment I had chosen. … Reaching out to Sarah Katerina was an absolute lifesaver.”DimitryPosted on Google, 2026
