Why this is different

Why this has never existed

Every property portal on earth is national — so nobody has ever been able to ask what a home asks in Madrid versus Manchester versus Milwaukee, measured the same way, in the same week.

133,494 listings from 32 live sources across 21 countries. Cross-country comparison published for 5 markets — the rest are listed below with the reason.

The period these figures cover: Every figure on this page is taken from listings this system first observed in the last 90 days — 2026-06-21 to 2026-09-19. It is a rolling window: an edition published next month covers the following 90 days, not a longer history. Earlier listings stay in our collection and are simply not counted here.

1 · Nobody else can do this, and the reason is structural

Zillow is American. Rightmove is British. Idealista is Iberian. Otodom is Polish. Every property data source on earth is national, because every portal is national — and no single actor sits across the borders to ask the same question in every market at once. That is not a hard engineering problem that nobody has solved. It is a shape-of-the-industry problem that nobody is positioned to solve. NOFEE reads the portals' own buyer-alert streams in many countries simultaneously, normalises them into one schema, and removes the duplicates.

2 · It is live, not an annual report

The corpus grows on its own from the portals' own alert streams. Come back next month and these numbers will be different, and current. Most housing data a reader can find was compiled months before it was published.

3 · The most trustworthy thing we publish is a market we withheld

Germany cleared every size rule and produced a clean-looking median. It was real and it was meaningless: its listings are a mix of monthly RENTALS and SALES, and a median across two populations describes neither of them. Nothing in the data says which is which, so the market is withheld rather than published with a number that would have been quoted. The exact counts are in the table below.

Netherlands — mixed deal types: 684 rent-shaped and 504 sale-shaped listings in one distribution (57% / 42%). A median across both describes neither. The corpus records no deal type, so sales cannot be separated honestly.

A reader who sees this knows what the other numbers are worth.

Questions this data can answer

These are open. If one of them is your question, say so and we will run it.

Where is the asking-price gap widest between neighbouring countries — and what does that say about who is actually moving?
Which markets list mostly rentals and which mostly sales, and what does that reveal about ownership culture? (This is exactly what tripped Germany.)
How long do listings sit before they disappear, compared across countries?
What share of listings come from private sellers rather than agencies, where that is measurable — the commission question, measured rather than argued.
What does the same €400,000 buy in each market, side by side?
Which capital cities are drifting away from their own national market?

What this never says

what any property is worth
a recommended asking price, for anyone's property or in general
whether a price is high, low, fair or a bargain
a forecast, a trend claim beyond the observed editions, or a transaction price
