Viiyoo screens every home for sale or to rent in your area against your own rules, works out what each would cost, and keeps a record a cabinet, a board or an investment committee can follow. Every figure is traced to its source and none comes from AI. Your own team reviews the work and releases it.
An estimated £801,456 a year of TA cost avoided. Simple payback: 8.5 years with the grant, 13.8 without.

1 With the estimated grant. Blended net yield 3.50%; grant 38.8% of the cost.
The rents sit £1.78 million a year below market rent. Each home carries its own rent evidence and the rules it was judged by.

| Homes let above the LHA rate, flagged | 30 |
| Homes more than 20% below market rent | 264 |
| Gross yield on value | 3.94% |
A first tranche of £473,000 for 3 homes. Removing the leasehold cap alone would lift the blended yield to 8.49% and add 3 homes.

Not a demonstration set. These are the published Local Housing Allowance and the homes advertised in Birmingham, counted the way Viiyoo would count them on your own patch, whether you house people there or invest there.
To rent
No more than 3 in 100 homes advertised to rent with one to three bedrooms could be let within the LHA. At the 30th percentile, where the LHA is meant to reach, advertised rents sit £180 to £400 a month above it.
For sale
Of 9,637 homes advertised for sale, 583 would return a gross yield of 7% or more if let at the LHA. Family homes barely feature: 32 of the 5,185 with three or four bedrooms.
LHA: DWP rates for 2026 to 2027, Birmingham. Rents: homes advertised to let between 10 April and 10 October 2026, each counted once. Homes for sale: advertised on 10 October 2026. Gross yield is before any costs, and the 7% threshold is set for this example. Advertised rents usually sit above the rents finally agreed. The tables and the method
Can the children still walk to school? Can the family reach their GP, and get to work on time? A placement check names the places a household relies on, measures the journey to each from every home you are considering, and keeps a sealed, dated record of what was checked.

Follow any figure back to where it came from. Here is the net yield of the top home in the Ealing screen, step by step, exactly as Viiyoo worked it out.
As the brief gives it. The yields and the price band are measured on it.

£14,260 on £275,000 is 5.19%, above the mandate's 3.5% net-yield floor.
Open any home and the reasons are there: each rule of your mandate, the evidence behind each figure, and what Viiyoo could not establish. The same goes into the committee pack.

Paste a committee's brief. Viiyoo fills in the mandate from it, quotes the words it used and lists what they did not say, for your team to check.
How many homes, what will be done to each, and any cost. Nothing runs until a person on your team confirms it.
Fits, fits on a condition, or out with the rule it broke. Every gap stated, with what would close it.
Review, override with a reason, release. Nothing released changes afterwards.
