17 earlier records at these addresses opened before this owner bought them, and are not counted here or in the score.

Buying and selling
Acquired 7 properties in the last three years, of 7 we have a recorded purchase date for.
Recorded purchase: May 2024.
From recorded property transfers. Buying or selling often is not itself a problem, and none of this affects the Public Record Score.
Company links are inferences from shared addresses, agents and name similarity — never a finding. Each one shows the evidence that produced it.
Tenant reviews (0)
Ordered by what other tenants found helpful (§3.6). Voting changes the order only — never a score.

“On record” means the authority published this citation but no abatement date, so we cannot tell you whether it was fixed — and we do not describe these as open. Sources differ on this: where one publishes a closure date, the row above shows it. How this works.
