Accuracy & Methodology
Clear methods, visible confidence ranges, and a continual improvement loop based on real outcomes.
Targets (Beta → Stable)
| Output | Metric | Target | Confidence policy |
|---|---|---|---|
| Rent range | Average error; % within range | ~20–25% → ≤ 15%; ≥ 80% within range | Use wider ranges when local comparables are thin; ask for a quick manual check |
| Works total | Average error vs quotes/invoices | ~25–35% → ≤ 20% | Room-level confidence shown; suggest contingency where needed |
| EPC match | Correct match rate | ~85% → ≥ 95% | Strict address checks with safe fallbacks |
| Yield/ROI | Carries input uncertainty | Ranges narrow as inputs confirm | Show assumptions and label what moves results |
Rent estimation
- Local history by postcode and property features set the baseline
- Listing details (condition/finish) adjust the range within sensible limits
- Wider range when fewer local comparables are available; prompts for a quick check
Works from photos
- Identify room type and apply typical scope (paint, flooring, fixtures, electrics)
- Local cost ranges with a confidence note per room
- Add contingency; lock figures once quotes arrive
Comps & EPC
- £/sq ft checks to spot outliers
- Careful EPC matching by address with strict checks
Financials & reporting
- Stamp duty, fees, running costs, mortgage; cash flow and ROI
- Exports: lender-friendly PDF and fully traceable Excel
Improvement loop
- Edit-to-improve: Your changes to rent or works update local baselines
- Regular checks: Ongoing evaluation on past deals; we watch for changes over time
- Release cadence: Updates weekly in beta; monthly once stable
