Greca House: an Athens agency since 2008
Greca House, an agency in Athens, carries on the brokerage that Iryna Rondyak set up in 2008. It sells homes, land, hotels and commercial property across Greece, publishes in six languages, and measures its own asking prices in research whose method and data anyone can read.
A brokerage that began in 2008
Greca House is a real-estate agency in the centre of Athens, and it carries on the brokerage of its founder and owner, Iryna Rondyak. She began working in Greek property in 2007 and established her own brokerage in 2008. That business, as the agency's About page puts it, continues today through Greca House, which she leads together with a team of agents and collaborators (she speaks Greek, Russian and Ukrainian).
The agency describes itself as an Athens brokerage for homes, commercial property, hotels, land and long-term lets across Greece. Its services are arranged around four kinds of client: buyers in Greece or abroad (Golden Visa buyers among them), owners who want to sell or let long-term, owners who live elsewhere and need help on the ground by arrangement, and brokers, lawyers, relocation firms, developers and advisers whose clients are buying in Greece. For a specific brief (a building to convert, a hotel, land to develop, one particular street) it will also search beyond its own listings and, in the words of its services page, give a clear answer when the property a buyer wants is not available at the price.
What it sells, and where
On 1 October 2026, the date of the snapshot behind its current research, Greca House had 676 public listings, 663 of them for sale. Most of those for sale were in Attica: 201 in the group it calls Athens Center, 137 in Athens North, 60 in the Rest of Attica, 44 in Athens South, and another 18 between Athens East, Piraeus and Athens West (8, 7 and 3), groups that are the agency's own.
The other 203 were further afield, 102 in the Peloponnese, 87 on the islands, 13 on the mainland and one in Thessaloniki. An office in central Athens thus evidently lists a fair part of its stock well beyond the city. The listings for sale can be browsed by the same regions.
Six languages, and a few homes you can walk through
Greca House publishes its site in six languages (English, Greek, Russian, Hebrew, Chinese and Arabic), and the listings, the research and the guides to buying each have a version in all of them. A buyer at home in one of those languages can therefore likely read up on the basics in it (the listings, the asking prices, the steps of a purchase and who does what) before writing to anyone. For an owner, the services page offers a full listing in six languages, with an interactive presentation for selected properties.
Every listing carries photographs and its details, and many add video or a 360-degree tour: on 15 October 2026, 152 of the agency's listings for sale had a video and 94 a 360-degree tour. For a few selected properties Greca House also builds an interactive 3D model, which can be explored floor by floor or walked through at eye level and is possibly the nearest thing to a first visit for a buyer who is far away. The agency labels these models plainly as illustrative visualisations, not measured surveys. On that day three listings had one (a new-build flat in Nea Ionia that can be shown with or without virtual furniture, a flat in Marousi and a villa by the sea at Loutraki, in Corinthia), shown at the end of this article.
Research with its method in the open
The part of Greca House that a careful buyer will likely want to read first is its research. From one dated snapshot of its own public listings it publishes reports on asking prices (what three budgets buy across Greece, and asking prices per square metre in Athens, neighbourhood by neighbourhood) and a market explorer by region. Its method page sets out how every figure is made: the asking price divided by the stated floor area, for homes of 20 square metres or more, given as a median (so that one unusual listing is unlikely to move it) with the middle half beside it. A group is published with six listings or more, called indicative at four or five, and left out below that.
Each figure is labelled as an asking price on the agency's own listings, which is not a sale price, not a forecast, not a valuation and not the whole market. Earlier snapshots are kept unchanged, and the data can be downloaded as CSV files under a Creative Commons licence (CC BY 4.0, with credit to Greca House). Its Athens report, for instance, rests on the 197 Athens-area apartments the agency had for sale on 1 October 2026, with a median asking price of 3667 euros per square metre. Of the twelve neighbourhoods it reports, the largest samples were in Marousi (31 apartments) and Kolonaki - Lycabettus (21), the latter with the highest median, 7391 euros per square metre.
The same listings and reports can also be read by AI assistants, Claude among them, through a public, read-only server that the agency publishes, with a link back to each listing or report.
How a viewing and an offer work
A purchase with Greca House, as its About page describes it, begins with a brief (area, budget, type of property, what it is for and when), which the agency matches against its listings, saying plainly when the right property is not on its books. Viewings are in person, or first through photographs, video and 360-degree tours where a listing has them. A buyer who cannot travel can, according to its guide to buying from abroad, ask the agency to view a property on their behalf and report back.
To arrange a viewing or make an offer you contact the office directly, and its services include the negotiation as well as the coordination with your lawyer, engineer and notary up to the contract. Before you commit, a lawyer checks the title, any encumbrances and the Cadastre record and an engineer checks the building's legal status (neither check, the guide says, is optional). The price, the timetable and what stays in the property are then agreed in writing, often with a deposit or a preliminary contract, and your lawyer should read every document before you sign or pay. The final contract is signed before a notary, with Greca House coordinating the appointments and the paperwork.
What the agency does not do, by its own account, is give legal or tax advice (that comes from the lawyer, notary, engineer and accountant), though after completion it can still help with the handover, the transfer of utilities and, by arrangement, local support for the property. To ask about one of its listings or a viewing, write to the Athens office through the contact page of grecahouse.com (its site says the office replies within one working day).
