You're about to spend £300,000 with less research than you'd put into a £300 phone

Think about the last time you bought a phone. You read the reviews. You watched a teardown or two. You compared the camera samples, argued with yourself about storage, checked whether the battery held up after a year, and probably asked a friend who already owned it. All of that for £300 — a thing you'll replace in three years and forget.

Now think about the last house someone you know bought. The average home in England and Wales changes hands for the better part of £300,000. And the research that goes into it, for most people, amounts to a Rightmove scroll, one or two twenty-minute viewings chaperoned by the person trying to sell it to you, and a survey they didn't fully understand paid for after they'd already fallen in love. A thousand times the money. A fraction of the diligence.

This is not a story about buyers being lazy. It's a story about information asymmetry — and the people on the other side of the table know exactly how it works.

The seller knows things you structurally can't

When you buy that phone, you and the manufacturer have roughly the same information. The specs are published. The reviews are independent. Nobody is hiding the battery size from you.

Property is the opposite. The person selling a house — and the agent representing them — sits on top of a mountain of things the buyer cannot see from the pavement. Whether the previous sale fell through, and why. What the neighbours are like. Whether that lovely bay window is the reason the EPC band is worse than the street average. Whether the extension that makes the kitchen so bright ever had permitted development rights, or whether it's an enforcement notice waiting to happen. Whether the flat's lease has quietly slid under 80 years, turning a cosmetic worry into a five-figure one.

The buyer, meanwhile, gets a floorplan with generous rounding and a set of photographs shot on a wide lens in the ten minutes of the day the sun hits the garden.

The asymmetry is not an accident of the market. It is the market. An estate agent's entire craft is managing what you learn and when. That's not villainy — it's the job. But it means the single most expensive decision of most people's lives is made with the seller holding most of the cards.

The maddening part: the information already exists

Here's what turns this from unfair to absurd. Almost everything a buyer needs to know is already recorded, already public, and already sitting in a government database.

Every sale in England and Wales since 1995 is in the Land Registry's price-paid data — thirty-one million transactions. Every home has an EPC on a national register, twenty-two million of them. The Environment Agency publishes flood zones as precise polygons you can drop a property onto. Local authorities publish planning decisions. Conservation areas are mapped. Every addressable building in the country has a UPRN — a unique reference number that, in principle, lets you stitch all of this together into one coherent picture of one specific house.

In principle. In practice, this data is scattered across a dozen portals, published in incompatible formats, keyed on postcodes and address strings that don't quite match, and gated behind interfaces built for surveyors and council officers rather than the family trying to decide whether to offer on number 14. The data is free. The synthesis is what's missing. And synthesis is precisely the thing a nervous buyer, three weeks into a chain, has neither the time nor the tooling to do.

So the information gap isn't a gap in the data. It's a gap in whose hands the data reaches. Professionals — agents, developers, the occasional cash buyer with a good solicitor — have long since learned to pull the threads. Ordinary buyers are handed a brochure.

The tooling gap is the whole opportunity

We didn't build AskHouse because property data was secret. We built it because it was unusable — and that unusability is a choice, not a law of nature.

The bet is simple: take the same public records the professionals rely on, resolve them all to the same building, and hand a plain-English answer to whoever asks. Not a PDF. Not a portal login. A question and an answer. Is this house in a flood zone? Do I need planning permission for that extension the last owner never mentioned? Is the price fair for what it is, or fair for the postcode average — which, as we argue at length elsewhere, is a lie?

That last point matters more than it sounds. Portals train you to think in postcode averages, and postcode averages flatten exactly the differences that decide whether you've overpaid. Two houses on the same road, same outcode, can differ by six figures for reasons that are entirely knowable — a flood line running down the back gardens, a school catchment boundary, a conservation edge — and entirely invisible in the average. The buyer who only sees the average is negotiating blind against a seller who isn't.

You can ask any of this directly — ask the house a question — or walk a property through every layer at once in the Explorer. The point isn't the interface. The point is that the answer should cost you a sentence, not a Saturday.

Buyers deserve the seller's-eye view

We're not romantic about this. Closing the asymmetry won't make bad houses good or turn everyone into a surveyor. Some of what a buyer needs still comes from a proper survey, a solicitor reading the lease line by line, a conversation with the people who'd become your neighbours. Data doesn't replace judgement; it arms it. What it does is move the starting line — so that when you walk into a viewing, you already know the questions worth asking, and you can tell when the answer you're given doesn't add up.

If you would not spend £300 on a phone without reading a review, you should not spend £300,000 on a house while the only person who's read the reviews is the one selling it to you.

That's the gap. Every post on this blog, every answer in our glossary, every layer in the product exists to close a little more of it. The seller has always had the seller's-eye view of your future home. We think you should have it too — before you offer, not after you've moved in.
