Property sale value range in lending decisions.

Property sale value range gives the sensible price range around the estimate, its width set by the confidence level rather than a fixed percentage band, published modelled with 99.24% coverage across England. Where modelled, review the current dictionary evidence and validate the estimate against your own reference cohort. Attribution and refresh period are in the dictionary.

Pretira publishes property sale value range modelled at 99.24% coverage across England, refreshed monthly, with declared and modelled kept separate.

16.1Decision rule
// routing pattern
IF (property_value_range.high - property_value_range.low) / property_value <= band_tolerance -> decide on data

On the sample record the range runs £340,000 to £530,000 around a £425,000 estimate - tight enough at high confidence to decide, wide enough elsewhere to signal a case for human eyes.

16.2Where it bites
01

Setting the tolerance a case must fall within before it clears on data.

02

Stress and downside context for funding-line and covenant reporting.

03

Explaining a decline defensibly - the range is the working behind the number.

16.3Provenance

Derived from the value and its confidence level; the lower the confidence, the wider the range. Anybody can print a band - the job is making it as tight as the evidence allows and saying so when it is not.

16.5FAQ

Three questions on this field.

Because a fixed band lies in both directions - too wide where the evidence is strong, too tight where it is thin. Tying the width to confidence keeps the range honest per property.

Yes. A common pattern routes on range width as a share of the value - narrow enough decides, wide enough escalates.

Test it alongside the value against a dated reference cohort. A bounded evaluation returns the error distribution by property type, geography and confidence band, including unmatched cases and limitations.
