Monthly statistics from portal listings by area and bedroom band. listings_added_n is the NEVER-REDUCED cohort dated by 'Added on' and undercounts new listings by reduction_share, by construction; listings_reduced_n is dated by the last reduction. Asking distributions are of what came to market that month. Yields: gross_yield_asking is cell rent x 12 over the same cell's asking price; gross_yield_avm_median is per UPRN-matched listing against the unit's AVM value. asking_to_sold and days_to_completion are on listings the registry matched to a sale within 18 months (sold_matched_n) — a match-rate-limited subset, NOT a sell-through rate.

days_to_completion is on the registry-matched subset (sold_matched_n), not a sell-through rate.
How to read G21’s evidence
The advertised sale cohort in G21 has a median asking price of £125,000 in Aug 2026, from a sample of 30. That is what sellers are asking, measured across the properties advertised in that month, and the set of properties advertised changes every month. 29 adverts were first observed in Aug 2026. 1 carried a recorded asking-price reduction in the same period.
Advertised monthly rent has a median of £925 pcm in Aug 2026, from a sample of 13. Advertised rent is not achieved rent. The published gross asking yield for G21 is 0.1% in Aug 2026, from a sample of 13, which sets area rents against area asking prices before any cost: vacancy, finance, maintenance, management and acquisition costs are all outside it, and it is not a forecast of the return on one property. 82 adverts were observed live in Sep 2026; Counted forward from our first observation of this area; adverts live before that date are not counted.
Asking price index, in the warehouse’s own words: “Hedonic (mix-adjusted for property type, bedrooms and new-build, within each local authority) index of ASKING prices from portal listings, 2022M01 = 100, smoothed toward the parent geography with posterior standard errors. Asking, not sold: it leads the repeat-sales index and includes what never sells. Rightmove is ~95% of the corpus. Published for the whole area; there is no bedroom cohort for this index.” The index is a level against its base period, not a price.
Asking rent index, in the warehouse’s own words: “Hedonic (mix-adjusted) index of ASKING rents from portal listings, 2022M01 = 100, smoothed toward the parent geography with posterior standard errors. Validated monthly against the ONS Price Index of Private Rents by local authority and not published in a month where the two disagree. Asking, not achieved. Published for the whole area; there is no bedroom cohort for this index.” The index is a level against its base period, not a price.

What is not published here, and why
Everything the warehouse does not publish for this area, with the reason it gave. A number missing from this page is missing because it was not measured, not because it was hidden.
- Median completed sale price
- No completed-sale median is published for this cohort
- Turnover rate
- No turnover rate is published for this cohort
- Completed sales
- No registry sales are recorded for this district
- Registry measures
- HM Land Registry Price Paid does not cover Scotland, so no completed-sale median, turnover rate or registry sale count is published for this area.
- Bedroom cohorts
- Bedroom cohorts are not published for this area in the current extract: a banded cohort resolves to the whole-area row, and repeating the parent’s number under six headings would state six measurements where there is one.
- Index membership
- This page is published and linked, and it is excluded from the submitted index while its evidence is below the floor described above.
- How this page was selected
- Selected on registered sales volume from the committed snapshot — a registry-volume proxy, not an evidence test.
