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.
marts_facts.listing_market
days_to_completion is on the registry-matched subset (sold_matched_n), not a sell-through rate.

How to read CM6’s evidence
The advertised sale cohort in CM6 has a median asking price of £500,000 in Aug 2026, from a sample of 125. That is what sellers are asking, measured across the properties advertised in that month, and the set of properties advertised changes every month. 87 adverts were first observed in Aug 2026. 38 carried a recorded asking-price reduction in the same period.
Registered completions in CM6 have a median of £426,740 in Jul 2026, from a sample of 15. Completions are registered after they complete, so this month and the advertised month above are different cohorts of different properties, and the two medians are reported side by side rather than compared. 17 completions were registered in Jul 2026. Turnover ran at 0.1% in Jul 2026, from a sample of 15 of the area’s stock.
Advertised monthly rent has a median of £1,500 pcm in Aug 2026, from a sample of 38. Advertised rent is not achieved rent. The published gross asking yield for CM6 is 0% in Aug 2026, from a sample of 38, 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. 1,025 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.

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.
- 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.
- Authority-grain totals
- Registered sales are counted per postcode district. Summing them across a local authority would be a total nobody measured, so no authority-grain figure is published beside the district here.
- How this page was selected
- Selected on registered sales volume from the committed snapshot — a registry-volume proxy, not an evidence test.
