Where we stand

Not an agency. On the buyer's side.

Buying a home in Spain is hard enough: prices keep rising, a good flat goes in days, and the seller and the agent know far more about it than you do. homie exists to even that out. It reads the public registers for you, so you go into the viewing and the offer knowing what they know.

No commission, no listings
We do not sell flats, we are not paid by anyone who does, and nothing in a report depends on whether you buy.
No invented valuations
Every figure comes from a public register or an open dataset, with its source and the date it was read. Where nothing is published, the report says so.
Your decision, better informed
We will not tell you whether to buy. We give you the facts and the questions to ask, so the choice is yours and made with open eyes.

Where the data comes from

42 sources. One report.
