Deploy capital with a paper trail.
From the mandate letter to a signed-off decision: Viiyoo turns your mandate into a plan the committee can test, then records the decision with the evidence it was made on.
Give us the letter. Get the mandate.
Write the mandate in plain English or upload the letter as a PDF or Word document. Viiyoo proposes the mandate from it, and a person checks it before it is saved.
- Proposed, not imposed. You check every figure in the proposed mandate before it is saved.
- Versioned like a document. Numbered, dated versions with exactly what changed, so the committee reads the mandate it approved.
| Version | Changed |
|---|---|
| v3 · 2 Oct | Affordable sleeve 15% → 20%; leasehold cap 50% |
| v2 · 18 Sep | Added W7; net yield floor 4.0% |
| v1 · 1 Sep | Proposed from the investment committee's letter |
A proposed mandate is checked by a person before it becomes a version.

Tell Viiyoo how much you're deploying, where, into which tenures and against which limits. It screens the market, underwrites every candidate for its sleeve, allocates within your rules and hands you a plan your investment committee can test.
- A real mandate, not a filter. Equity, leverage, horizon, an income, growth or impact objective, and sleeves with their own tenure, rent basis and grant.
- Your limits enforced. Caps on area, single asset, leasehold and grant reliance; yield floors with and without grant; Article 4 and flood risk avoided. Every exclusion gives its reason.
- Stress-tested. Up to seven scenarios, from grant not awarded to rents down and costs up, and a first tranche with its worst-case cash.
- Honest about capacity. A feasibility frontier shows how much the market can absorb at each yield floor, and what relaxing each rule would buy you.
- Watched. Scheduled re-runs show which homes entered or left the plan and why, and bridge the change in yield.

Real Viiyoo screen from a demo organisation. Addresses are replaced with descriptions.
Where the money goes, and what it costs.
A plan is not one number. It shows where the capital lands, how it holds up when rents fall or costs rise, and what each of your rules is costing you.

Market capacity, area by area.
How much each local authority takes, against how much eligible stock it holds and its median yield, on official boundaries.

Stress before you commit.
Closed-form shocks to rent and costs, alone and together, with the yield on cash and total return either side of the base. A scenario that cannot apply says why it is not shown.

Every rule, and what it costs.
Each limit, whether the plan meets it and why, and what relaxing that rule alone would change in yield, capital and homes. Hard limits are never crossed; a target is reported, not enforced.

A decision you can stand behind later.
The case for a purchase is drafted on the plan's pinned evidence, frozen with its pack and signed off by a second person, so a year later anyone can see what was decided, on what, and by whom.
- AI drafts, figures are checked. The draft is written from the evidence, and every number in it is checked against Viiyoo's results.
- Four eyes, always. The person who drafts a decision can't sign it off. No API route can submit or sign off a decision.
- Outcomes measured. Later, Viiyoo shows how decisions fared against what then happened.
- Drafted on the plan's pinned evidence; every figure checked against Viiyoo's results.
- Frozen with its committee pack, so the evidence can't move under it.
- Signed off by a second person, with their note.
A whole file, in one run.
Give Viiyoo a client's file or a portfolio and it matches, values, underwrites and judges every home against a mandate in one run, with a quote before it starts and results as rows.
- The same methods. Each home is valued and underwritten exactly as on its own property page.
- Every row explained. Homes that can't be matched or valued say why.

We'll show you the plan Viiyoo builds from it, and what it holds back and why.
