Repairs, vendors, and receipts

Property documentation is not one job, it's four jobs (move-ins, move-outs, maintenance, lease violations) plus a retention schedule that ties them all together. Most landlords have partial systems in three of the four categories and nothing in the fourth, and the fourth is where the next expensive dispute will come from. This pillar is the reference: every record category, the artifacts inside each, the retention rules by jurisdiction, the digital-vs-paper sufficiency standard, the audit-ready bar, and an interactive scorecard that grades your current system honestly.
