This is a genuinely useful system, and the single overwritten PDF is the part most people miss. Keeping one canonical file instead of a chain of versions means you are never hunting for "the most recent one" at the worst possible time.
A few things worth adding for anyone reading this who is new to the terminology:
A lease roll (also called a rent roll) is a summary of every unit in a building, who is in it, what rent they pay, when their lease expires, and any concessions like a free month. It is one of the first documents a buyer or lender asks for, and they often want it fast.
Due diligence is the period after a purchase contract is signed when the buyer investigates the property before committing fully. That window can be short, sometimes two weeks, so having documents ready to send same-day is a real competitive advantage for a seller and a sign of professional management to an operator.
One thing worth confirming, which I would verify with a transaction attorney in your state: whether the version of the lease roll you share needs to be certified as accurate on a specific date, and whether any disclosure obligations attach to it. Some purchase contracts require a seller certification. That is a legal question, not something I can answer here, but worth asking before the next one.
For anyone building a system from scratch, the three-folder structure described above, entity, lender, property, is a clean starting point and consistent with how institutional owners tend to organize asset documents.
What does your property folder include beyond the lease roll? Curious whether others are keeping executed leases in the same place or filing them separately.
