The problem

Leaseholders ask who pays for a window, a balcony or a leaking pipe, and the answer sits in a lease that may run to 80 pages, with different versions for different flats. If a property manager answers 10 of these questions a week and each takes 20 minutes of searching the lease, that's 200 minutes a week, about 14.3 hours a month.

What the AI does

Claude Projects keep a block's leases and deeds of variation together, so every chat in the project works from them. For each block, the manager uploads the lease versions once and asks Claude for a matrix: who repairs and who pays for each part of the building, what the service charge can cover, how it is split between flats and when accounts are due, with the clause number on every line. Day to day, the manager asks a question in the block's project, opens the clause Claude cites and replies to the leaseholder. Leases name leaseholders, so the firm uses the Team plan, which shares projects across the team and doesn't train on business data by default.

A worked example

A four-person block management firm in Brighton manages 25 blocks. Two property managers keep a Claude Team project for each block holding its lease versions, and answer repair and service charge questions from it after checking the clause.

Before

20 minutes searching the lease for each of 10 questions a week: about 14.3 hours a month

After

About 5 minutes to ask, open the clause and reply: about 3.6 hours a month

What it's worth

About $430£323€384A$620C$607 a month in time saved, against about $40£30€36A$58C$56 to $51£38€45A$73C$71 for two Claude Team seats. 15 minutes saved on each of 10 questions a week is 645 minutes a month (150 × 4.3), about 10.75 hours at an assumed $40£30€36A$58C$56 an hour.

How to set it up

  1. Set up Claude Team for the two property managers, $20 (about $20£15€18A$29C$28) per user a month billed annually or $25 (about $25£19€23A$36C$36) monthly, minimum 2 users, after checking Anthropic's data processing terms.
  2. Create one project per block and upload each lease version, any deeds of variation and the lease plan as text-searchable PDFs, each under 30 MB.
  3. Ask for a repair and service charge matrix with the clause number on each line, noting which flats each lease version covers.
  4. Check the matrix against the leases once, correct it, and save the checked version in the project and the block file.
  5. For each leaseholder question, ask in the block's project, open the cited clause yourself and reply from your usual system.

What goes wrong

  • Claude can give a confident answer the clause doesn't support, or mix up two lease versions. Always read the clause before replying; the lease, not the summary, decides what is recoverable.
  • Project files are limited to 30 MB each, and a scanned lease with no text layer may not be read properly. Split large scans and run them through OCR first.
  • Disputes over recoverability, section 20 consultation questions or anything heading to the tribunal need a senior manager or a solicitor, not an AI answer.
  • Free and Pro can't share projects with colleagues, and training on chats is opt-out. Team shares projects and has training off by default.
