Methodology
How FindMyProperty scores opportunities
FindMyProperty's composite score is a 0–100 screen of listed NZ residential do-ups and rentals: 45% roi, 17.5% timeline, 17.5% confidence, 20% location. Verdicts start at Strong Buy 75, Buy 55, Maybe 35. It is a ranking filter, not a valuation or buy instruction.

Composite weights
Each component is 0–100. The composite is the weighted average. ROI is the largest weight because return capital or pay a yield is the job.
| Component | Weight | What a high score means |
|---|---|---|
| ROI | 45% | Modelled flip ROI or gross yield on the recommended strategy path (30% flip ROI or 15% yield maps to 100). |
| Timeline | 17.5% | Estimated renovation weeks at or under the 8-week target score 100; longer jobs score lower. |
| Confidence | 17.5% | ARV comparable-sales quality averaged with a Tenancy Services bond-sample cap — not a photo beauty contest. |
| Location | 20% | Population-growth baseline plus nearby employment, daily convenience, and education amenity. |
Renovation $/m² bands
Vision classifies the listing, then the cost model applies a per-square-metre band to floor area, adds photo-flagged line items, and a 15% contingency. These are internal bands — not a builder quote.
| Level | NZD / m² | Typical scope |
|---|---|---|
| NONE | $0 | No material programme |
| COSMETIC | $500 | Paint, minor fixes, tidy |
| MODERATE | $1,200 | Kitchen/bath refresh, flooring |
| MAJOR | $2,000 | Full kitchen/bath, rewire, replumb |
| FULL_GUT | $3,500 | Strip toward frame, full interior rebuild |
Verdict bands
Cut from the composite. Strategy labels are Flip or Rental against 15% modelled flip ROI and 9% gross yield — there is no Hold bucket.
| Verdict | Composite | How to use it |
|---|---|---|
| Strong Buy | 75–100 | Worth a full file (builder, rent check, LIM, title). Not a bid on the number alone. |
| Buy | 55–74.9 | Meets the rank band; stress-test reno and ARV before you commit. |
| Maybe | 35–54.9 | Borderline. Watch price, or only view if the street already fits your mandate. |
| Pass | Below 35 | Does not meet the screen. Skip unless you have a thesis the model cannot see. |
Data sources
- Active listings. Listed NZ residential stock ingested from Trade Me and related public listing feeds.
- Rents. Gross yield uses MBIE Tenancy Services bond lodgements — median weekly rent for comparable suburb and bedroom count, not vendor appraisals.
- ARV comps. After-repair value is supported by comparable sales quality; thin comps lower confidence.
Confidence
Confidence is the average of ARV confidence (comparable sales) and a rental cap from bond sample count: each Tenancy Services sample adds about five points, capped at 100. Sparse comps or a thin bond book lower the composite even when the yield print looks aggressive.
Filter, vision, and publication
We first remove listings that fail baseline criteria (price, title, listing quality, population) before deeper analysis. A text signal from the listing write-up runs before paid image analysis so we skip vision on copy that is obviously not a do-up. Listings with outlier metrics or ambiguous low-renovation signals can be held for manual review. New-build / move-in-ready marketing with a negligible programme can skip a composite so turnkey stock does not crowd value-add ranks.
What the score cannot see
Vision cannot see behind linings. ARV cannot see an unconsented sleepout. Bond medians cannot see the tenant you will actually get. We do not score flood or meth from photos unless the image itself shows damage. FindMyProperty screens listed NZ residential and value-add stock — not commercial inventory.
