As answered by people managing Mockoon and LetSorted.
LetSorted's answer:
LetSorted is the only property management tool built specifically for UK self-managing landlords that automatically builds a court-ready evidence trail as you manage. Every inspection is signed by both parties, every maintenance request is timestamped, every rent payment is logged — so if a tenancy goes wrong, your evidence is already there.
LetSorted's answer:
Most UK landlord software focuses on accounting and rent tracking. LetSorted covers the full tenancy lifecycle — from AI-powered tenant screening to move-in inspections, periodic checks, maintenance logs, and a one-click Dispute Evidence Pack. It's also the only tool built around the Renters' Rights Act 2025, with RRA-compliant contracts and Section 8 evidence support built in.
LetSorted's answer:
UK self-managing landlords with 1–5 properties who currently juggle spreadsheets, folders, and WhatsApp. They don't want to hire a letting agent, but they do want to stay compliant and protected — especially after Section 21 abolition.
LetSorted's answer:
The founder moved to the UK in 2022 and spent two weeks navigating paper forms and photocopied contracts just to rent a house. Three years later, researching buy-to-let investment, he couldn't find software that would protect a small landlord under the new Renters' Rights Act. So he built it — first for himself, then for everyone.
LetSorted's answer:
