Start with the evidence you actually have
A move-out dispute becomes easier to understand when each deduction can be compared with a lease term, a report, a photo, a date or an invoice. You do not need to publish your documents in a forum to get organized.
What was deducted?
Separate painting, cleaning, floors, keys, utilities and other lines instead of treating the whole statement as one amount.
What supports each line?
Look for reports, dated photos, invoices or quotes, and the part of the lease the landlord refers to.
When did it happen?
Write down key handover, inspection, report, statement and reply dates before you answer.
