How to Keep Property Maintenance Records for a Small Portfolio

Record-keeping advice written for large portfolios does not transfer. It assumes a team, a
system, and someone whose job includes filing. A person with four or five units has none of
those, and a scheme that assumes them will be abandoned within a quarter.

What follows is deliberately minimal. The aim is a system that survives being neglected for a
month, because it will be.

Folder per property, folder per year inside

That is the whole structure. Resist further subdivision.

Deep hierarchies fail for a specific reason: every filing decision becomes a question, questions
create hesitation, and hesitation means things get left in the inbox "for now". A flat structure
with obvious answers gets used.

Name files so they sort usefully: date first, then what it is. 2026-09-14 roof repair invoice
sorts itself and needs no thought.

Four things per property

1. The documents. Lease, title, plans, warranties, certificates, insurance.

2. The maintenance log. One row per job: date, unit, what, who did it, cost, who paid.

3. The evidence. Invoices, photographs, contractor reports — named so they can be matched to
log rows.

4. The register. A short list of the expensive things: plant, roof, services, with rough age
and condition.

Four things. If you have those and they are current, you can answer almost any question that
will be asked of you.

The log is the important one

Documents sit still and can be found when needed. The log is the thing that decays, because it
requires action at a moment when you are busy with something else.

Make it as small as possible so the barrier is low. Six columns. One line. Entered the day the
work happens, not at month end — retrospective entry loses the small items, and the small items
are most of them.

A spreadsheet is entirely adequate for a small portfolio and always will be. The failure mode is
never that the spreadsheet was insufficient; it is that nobody filled it in.

Get it off your phone

The most common single point of failure in a small portfolio is that the evidence lives on the
owner's phone.

Photographs of work, messages from contractors, receipts — all of it on one device, unbacked. A
lost phone takes the property's history with it, and there is no way to reconstruct it.

Move images into the property folder on a regular rhythm. Monthly is fine. Make it a habit
attached to something else you already do, such as when you reconcile the accounts.

Keep for the length of your exposure

Set retention by when questions can still arise: through the tenancy and comfortably beyond it,
longer for anything structural, longer again for anything safety-related or with a warranty
attached.

Confirm what applies where you are — requirements differ by jurisdiction and by the type of
property. Then write your chosen period down so it is a decision rather than a drift.

Review annually, briefly

Once a year, open each property folder and check three things: that the register still reflects
reality, that the log has no obvious gaps, and that nothing important is sitting outside the
folder.

An hour per property. This is also the natural moment to read the year's costs per unit, which
is where the useful decisions come from.

Write the handover note now

If somebody else had to take over tomorrow — a partner, an agent, an executor — could they?

Write a single page: where the records are, which properties, who the contractors are, what is
currently outstanding, and anything they would not guess. Keep it with the records.

This takes twenty minutes and is the highest-value document in the entire system. It is also the
one nobody writes, because it only matters on the day it is needed, and on that day you are
usually not available to explain anything.
