A free property appraisal that shows the true discount

Most free property calculators are a lead-capture form with arithmetic attached: you get a reassuring number and they get your email and a tracking cookie. The free appraisal here is the opposite transaction. It runs the real engine — the same one behind every Deal Room — on figures you type in, returns the working, and asks for nothing. No account, no sign-up, and nothing tracked.

What does it actually compute?

The buyer-side arithmetic, in full. It takes the price, the works, the finished value and the finance, and returns the true discount against open market value, the transfer tax at the rate the buyer's circumstances attract, the costs across the hold, and the deal's behaviour under the Red Team stresses. These are figures that depend only on what you supply, so the engine can compute them honestly without knowing anything about a seller.

Why does it not return a Deal Score?

Because an honest Deal Score cannot be computed from the buyer's side alone. Scoring runs Seller Protection and the motivation diagnostics, and both need answers about the seller — their situation, their reason to move, whether they are in a position to give free and informed consent. Nobody has spoken to that person, so those answers do not exist, and a score computed as though they did would be inventing the most important inputs. The appraisal returns the arithmetic it can stand behind and says, plainly, why the score is not among it.

That refusal is the feature. A tool that handed you a Deal Score from four numbers and no seller would be faking exactly the part that matters, and the honest version is the one that tells you where its own knowledge stops.

Why is nothing tracked?

Because the appraisal is not a funnel. The deal lives in the query string rather than in an account, and the page is deliberately kept off the analytics route allowlist, so no pixel sees the figures you entered. You can run it, close the tab, and leave no trace — which is the correct default for a tool that exists to give you a straight answer rather than to capture you.

What it is good for

• Pricing a purchase before you negotiate, so the true discount is known rather than guessed.
• Seeing the transfer tax at your own rate, including the additional dwelling surcharge a company pays from the first pound.
• Checking whether a deal survives the Red Team stresses before you commit cash to it.
• Getting a straight answer without handing over an email or picking up a cookie.

The appraisal gives away the engine because the engine is not the moat — the discipline around it is. A number you can trust, computed the same way as the paid product, with the one figure it cannot honestly produce left out and explained, is a better advertisement for the platform than any figure it could have faked.
