Paste a listing. We’ll tell you what it’s worth.
Frankly checks the price against the median for similar listings in the same neighbourhood, verifies the surface area against the Spanish Catastro, and surfaces recent comparable sales nearby.

What you get back
Frankly works out the price per square metre of the listing you paste, then places it against comparable homes on the market nearby. Three outcomes:
Below the Frankly Median — the asking price per m² sits in the lowest quarter of comparable listings.
At the Frankly Median — it sits in the middle half. This is the common case, and it is not a criticism.
Above the Frankly Median — it sits in the top quarter.
Alongside the verdict you get a Frankly Fair Value range — the 25th to 75th percentile of what comparable homes ask per m², applied to this property’s size. It is a benchmark for comparison, not an appraisal.
If fewer than 12 genuinely comparable listings exist, you get “Not enough comparables” instead of a number. We would rather say nothing than say something confident and wrong.
How the comparison is built
Location first. We compare within the sub-district where the data allows it — Trafalgar rather than all of Chamberí, Jerónimos rather than all of Retiro. Only when that pool is too thin do we widen to the full district.
Size. Comparables sit within 20% of the property’s surface area, either way.
Product type. Penthouses (áticos, top-floor flats with private terrace) are compared with penthouses, chalets and townhouses with their own kind, flats with flats. An ático carries a premium that would distort a flat’s benchmark.
Market tier. The benchmark is built from the Madrid luxury agencies we track. Mid-market inventory still appears on Frankly, but stays out of the comparison — its pricing distribution would pull the median somewhere it doesn’t belong.
Outlier guard. One eye-catching listing shouldn’t move a neighbourhood’s median, so comparables far outside the local price band are excluded before the median is taken.
Two things worth being straight about. These are asking prices, not sold prices — Spain publishes no open record of what luxury homes actually close at. And the median is taken across every comparable that passes the filters; we don’t trim the ends afterwards. Where the Notariado (the Spanish notaries’ association, which publishes the median price per m² of deals actually signed) has data for the area, we use it to estimate how far asking typically sits above closing.
Why we check the Catastro
The Catastro is Spain’s official property register — the government’s record of every building’s surface area, year of construction and registered use.
Listings and the register often disagree, usually for an innocent reason. A listing may quote superficie construida (built area, which includes a share of stairwells and landings) where a buyer is thinking in superficie útil (usable interior floor area). The gap is commonly 10–20%.
That matters here because every Frankly verdict is a price per square metre. If the square metres are wrong, so is the verdict. So we check the listing’s claim against the register and tell you when the two differ, and by how much.
The check is free, needs no account, and the data comes straight from the public Catastro service. Nothing about your search reaches the listing agency.
What you can paste
Frankly covers Madrid’s prime districts across the luxury agencies working in them — currently 5,422 listings from 42 agencies, re-checked daily.
Paste a listing URL from any of them. If it’s already in our corpus you land on its analysis immediately; if we haven’t seen it, we fetch and analyse it on the spot.
If the site isn’t one we cover, we’ll say so rather than guess. Tell us which agency you’re looking at and we’ll look at adding it.
Questions people ask
Is it really free?
Yes. The analysis, the fair value range, the comparables and the Catastro check cost nothing. An account is needed to see the verdict itself — that is the only wall, and there is no card behind it.
Do you tell the agency I looked?
No. Browsing and analysing are anonymous. Your details reach a partner agent only when you fill in the consultation form yourself and tick the consent box on it.
Is this a tasación?
No. A tasación is the formal valuation a certified valuer produces, usually because a bank commissioned it before lending. Frankly is a market benchmark: what comparable homes are asking, right now, per square metre. Useful for deciding what to offer; not a substitute for the bank’s document.
Why “above the median” rather than “overpriced”?
Because above the median is often the right price. A better floor, a quieter street, a finished renovation, a terrace the comparables don’t have — plenty of reasons a home asks more than its neighbours and is worth it. We show you where the price sits and what it is sitting against. The judgement stays yours.
The listing agency says the price is fair. Who’s right?
Quite possibly both. The agency is engaged by the seller — that is the job, and most do it well — and they know things about a property that no dataset holds. Frankly knows what every comparable home nearby is asking. Those are different kinds of knowledge, and the second is the one buyers usually arrive without.
What if the listing I want isn’t covered?
Send it to us. Coverage grows by request more than anything else, and knowing which agency you were reading is the most useful thing you can tell us.
Want someone on your side of the table?
The listing agency works for the seller. Brian is a Frankly-verified buyer’s agent in Madrid, and he works for you — viewings, negotiation, and the Spanish paperwork: the nota simple (the land-registry extract showing who owns the property and what debts sit on it), the NIE (the foreigner’s tax number you need in order to buy), and the notary appointment.
