B45 9

1,986 tracked properties. Each month you receive every one of them ranked by how likely it is to come to market in the next 12 months, each with an off-market value and its confidence (already-listed homes are removed and reported separately), plus the properties that just came to market and live probate flags.

The record

Canvass a random fifth of B45 9 (398 homes) and about 11 would come to market in the year. Canvass the fifth we ranked highest and 32 did — 2.8× the instructions for the same effort.

Each January the model ranked every home in this sector using only information available on that day. A year later we counted its top fifth.

Year	Tracked homes	Top fifth that listed	Background rate	Advantage
2022	1,787	20 of 358	2.1%	2.7×
2023	1,887	14 of 378	1.7%	2.1×
2024	1,986	32 of 398	2.9%	2.8×

Numbers are floors: the listing record we test against misses some genuine listings, so true hit rates are likely higher. Full methodology.
