A clear view of the score.
Model 2: an explained points system for comparing listing details. Sale and rental scores measure different things; compare properties of the same listing type.
What the references mean
These are fixed product assumptions inherited from the prototype. They are not verified current Northern Ireland averages, local valuations or a live market feed.
- Purchase price: £185,000
- Purchase price per square foot: £135
- Monthly asking rent: £750
The model does not use price trends, rental demand data, comparable transactions, enquiries or listing completeness. The postcode contribution is a fixed weighting, not measured demand.
For-sale score: up to 100 points
Yield potential: up to 40 points
Gross yield = estimated monthly rent × 12 ÷ asking price × 100. No financing costs, expenses or tax are deducted. The unrounded percentage determines the points.
| Gross yield | Points |
|---|---|
| 10% or more | 40 |
| 8% or more, below 10% | 35 |
| 6% or more, below 8% | 28 |
| 4.86% or more, below 6% | 22 |
| 3% or more, below 4.86% | 14 |
| Above 0%, below 3% | 6 |
When a positive rent estimate is missing, a price fallback awards at most 22 of the 40 points. It is not a yield estimate:
| Price as a percentage of reference | Points |
|---|---|
| Up to 60% | 22 |
| Over 60% to 80% | 16 |
| Over 80% to 100% | 10 |
| Over 100% | 5 |
Purchase price comparison: up to 25 points
With floor area, asking price per square foot is compared with the purchase-price-per-square-foot reference.
| Price as a percentage of reference | Points |
|---|---|
| Up to 60% | 25 |
| Over 60% to 80% | 20 |
| Over 80% to 100% | 15 |
| Over 100% to 130% | 10 |
| Over 130% | 5 |
Without floor area, asking price is compared with the purchase-price reference; the fallback awards at most 17 points:
| Price as a percentage of reference | Points |
|---|---|
| Up to 70% | 17 |
| Over 70% to 100% | 12 |
| Over 100% | 6 |
Property fundamentals: up to 25 points: the EPC, postcode group and room criteria below.
Platform BMV flag: up to 10 points: 10 if flagged by the platform, otherwise 0. This is not an automated valuation or proof of a discount.
Rental score: up to 100 points
Rent affordability: up to 75 points: monthly asking rent is compared only with the monthly rent reference. Lower rent earns more points. This broad comparison does not adjust for property size or local market conditions.
| Price as a percentage of reference | Points |
|---|---|
| Up to 70% | 75 |
| Over 70% to 85% | 60 |
| Over 85% to 100% | 45 |
| Over 100% to 120% | 30 |
| Over 120% | 15 |
Property fundamentals: up to 25 points: the same criteria below. Purchase price, gross yield, sale-price-per-square-foot and the BMV flag do not contribute to rental scores.
Property fundamentals and missing data
EPC: up to 10 points: A: 10; B: 9; C: 7; D: 5; E: 3; F: 1; G: 0. Missing or unrecognised EPC receives a default 3 points, not an inferred rating.
Postcode: up to 8 points: BT1, BT2, BT3, BT4, BT5, BT6, BT7, BT8, BT9, BT10 receive 8; BT11, BT12, BT13, BT14, BT15, BT16, BT17, BT18 receive 5; other or unknown districts receive 2. Spacing and letter case do not change the district.
Rooms: up to 7 points: two or more bedrooms receive 4 points, plus 3 if bathrooms are at least half the bedrooms rounded up, otherwise plus 1. One bedroom receives 2; zero or unknown bedrooms receive 0. Unknown bathrooms do not qualify for the higher award.
Missing price inputs receive no points in price-dependent categories. Missing rent or floor area uses the documented sale fallbacks. Missing data is not rescaled to a perfect score.

Badges and search order use the saved score. A property with an older or mismatched score shows a separately labelled recalculated preview. Its saved score is not silently replaced by that preview.
Scores summarise model inputs, not expected profit or investment suitability. Check asking prices, rent estimates and property condition independently.
