Deploy capital to a mandate. Defend every home in it.
For funds and investment teams buying UK residential at scale. Viiyoo turns your mandate into a plan of real homes for sale, shows what each of your rules is costing you, stresses the plan, and hands the committee a pack it can test, with every figure traced to its source.
Real Viiyoo screen from a demo organisation.
A mandate, a budget and a committee to answer to.
Where should the capital go?
Which areas can absorb it at your yield floor, how many homes that means, and how long it takes to buy them.
What are the rules costing you?
Every limit in the mandate, whether the plan meets it, and what relaxing it alone would buy in yield, capital and homes.
Will it stand up later?
The plan under stress, every home's evidence pinned, and a decision record the committee, the auditors and the next fund can read.
From the mandate letter to a plan of real homes.
- The mandate, from the letter. Geography, sleeves, yield floors and spread limits filled in from your words, with what they did not say listed for your team to check. Every version is kept.
- A plan from the live market. Homes for sale across your areas, screened, underwritten and ranked by the figure your mandate names, never a blended score.
- Full underwriting. Stamp duty for the nation the home is in, running costs, lender stress test, grant where it applies, and returns with and without it.
- Ranked on the rent each sleeve collects. A social housing sleeve is underwritten at the rent it will actually be let at, not the market rent.
- Stress and capacity. Grant not awarded, rents down and costs up, alone and together, and how much the market can absorb at each yield floor.

Every figure says where it came from.
Values come with a range and a confidence level, tested on homes that have sold, and the results are published. No figure comes from a language model.
sale prices fell inside the range Viiyoo gave
median difference from the price paid where confidence is high
average bias: Viiyoo values neither high nor low
figures produced by a language model: the arithmetic is tested code
Homes valued as they stood on the day they sold: 290 sales across 40 postcode districts in England and Wales, July 2025 to June 2026. Measured 28 September 2026.
Committee packs, a decision record, your own sign-off.
Committee-ready packs
Shortlists, plans and appraisals as packs, workbooks and CSVs in your branding, each figure with its source and date.
A decision record
A decision drafted on pinned evidence, frozen with its pack and signed off by a second person on your team.
Released by your team
The platform does the work; your own person reviews and releases it. Nobody at Viiyoo signs off your results.
Into your own systems
The Claude and ChatGPT connectors, single sign-on and SCIM on every plan, and an API for early-access teams. Integrations.
What to expect, and what not to.
Is a Viiyoo value a formal valuation?
No. Viiyoo's values support an investment decision; where a RICS Red Book valuation is required, for lending or reporting, you still need one.
Does Viiyoo give investment advice?
No. Viiyoo provides analysis and evidence, not advice. Your team makes and releases every decision.
Are forecasts included?
Not yet. Market forecasts, 3, 6 and 12 months ahead with an upside and a downside, are being built; they will join every plan when they are live, with their accuracy published.
How is it priced?
One product on monthly plans that differ only by volume, from £1,500 a month, with a 3-month initial term. See the plans.
