£81,174,572 across 5 titles

Why this is read as one transfer

it spans 2 districts, which weakens the case; the price is not a round figure, so the same sum on the same day across several titles is not coincidence; every title is filed as Category B, HM Land Registry’s "additional price paid" class.

The £81,174,572 figure is the consideration for the whole transfer. It is repeated against each title below in the raw register — it is not what any one of these properties is worth.
