Southwark — 480 active Article 4 directions (2 HMO-specific in records); verify HMO exposure with council.
Inner London; dense Victorian and Georgian stock with mixed-tenure regeneration; established bridging and BTL market.
480 active Article 4 directions in our records create a heavy regulatory footprint — mostly conservation-area driven; verify HMO-specific coverage with council directly.
Strong Article 4 presence requires deal-by-deal assessment; HMO plays depend critically on verification of actual council HMO-related Article 4 footprint beyond our 2 recorded directions.
