Send us a real brief How engagements work
An acquisition screen in Viiyoo, ready for review: 9 of 32 homes listed for sale in Ealing shortlisted against an Ealing yield mandate, with 21 excluded, 2 that Viiyoo cannot tell about, 7 gaps across 11 homes and 1 override. The top home, a 1-bed flat in Ealing W5, is open to its ledger: each rule of the mandate, what was found and the outcome, measured on its £275,000 asking price, beside Viiyoo's value of £352,000 in a range of £243,000 to £424,000 at low confidence, market rent of £1,750 a month from 543 comparable lettings, a net yield of 5.19% on the price at the mandate's costs, cash flow and lender stress.
The release dialog: the packs are composed from the result as it stands, with its one override, frozen with their fingerprints and approved in your name; recipients are emailed a link that needs a sign-in, not a file; after release nothing in the revision changes.

How it works

From brief to packs, in three steps.

  1. 01

    Your brief

    Say what you want in your own words, with a list, an area or a saved search, and the mandate to judge it by. Nothing runs until you confirm the quote.

  2. 02

    Viiyoo does the work, in the open

    Every home is matched, valued, rented, underwritten and judged against each rule of your mandate, each step shown in plain words as it runs.

  3. 03

    You review, and a named person releases

    Read the shortlist, the exclusions and the gaps, and override with a reason. Nothing reaches your readers before release, and nothing released changes.

Why you can trust it

A result you can check line by line.

  • No figures from AI

    Values, rents, yields and verdicts come from tested calculation code. A language model never produces a figure or picks a home.

  • Gaps stated, never filled

    What could not be established is listed with what would close it, not papered over.

  • A person releases

    Nothing is sent until a named person on your team releases it. Overrides carry a name and a reason.

  • Accuracy in the open

    We value homes that have already sold and publish how far out we were.
