Is buy to let worth it: BTL Yield Benchmark

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

3 of the 6 named sources that could be read published a usable figure; 3 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in GBP (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 13 figures, never sentences; 33 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): gross yield per local authority and London borough computed as the official median monthly rent x 12 over the official median sale price - two national statistics releases their own publishers never join - with the ranking, the change across the series and the spread between the best and worst borough

33 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
