Onesta Real Estate
About us
Nice to meet you!
We're Onesta
Onesta Real Estate is turning more and more of the map orange – from the harbor in Scheveningen to the streets of Purmerend, and even the sun-drenched coasts of Spain. Whether you're selling your home, searching for your dream house (here or there), looking for a reliable tenant or need a property valuation – we’ve got you covered. With our in-house mortgage advisor, we move fast, and our agents think along with you – at your kitchen table, online, or even under the palm trees. Onesta blends local expertise with international ambition. Your real estate, our mission.
