Buying a resale (secondhand) apartment feels safer than buying off-plan. You can see the actual unit, meet the neighbors, and check the view. But the biggest risks in a resale are invisible during a viewing: the health of the building’s finances, looming repair bills, and restrictions that limit what you can do with the unit. This guide gives you a due-diligence process focused on what you cannot see with your eyes.
The unit is fine; the building is the question
When you buy an apartment, you buy two things: a private unit and a share of a shared building. Most buyers inspect the first thoroughly and the second barely at all. Yet a failing roof, an underfunded reserve, or a pending special assessment can cost you more than any cosmetic issue inside the unit.
Read the sinking fund first
The sinking fund (or reserve fund) is the pooled money set aside for major repairs: roof, lifts, facade, plumbing risers. A healthy fund means owners have been paying realistically and big repairs are covered. A near-empty fund means the next major repair will arrive as a special assessment, a surprise bill split among all owners. That bill can run into thousands per unit.
Ask for the fund balance, the annual contribution, and the schedule of upcoming major works. A building with 40-year-old lifts and a thin reserve is telling you something.
Service charges: the cost that never appears in the listing
Monthly service charges fund cleaning, security, insurance, and management. They are easy to overlook because they are not part of the purchase price, yet over a decade they can total a large fraction of what you paid. Two things matter: the current level and the trend. Charges that have jumped sharply in recent years signal either rising costs or past underfunding catching up.
Documents to demand before you commit
- Recent management accounts and the reserve fund balance.
- Minutes of the last two or three owners’ meetings. These reveal disputes, planned works, and problem neighbors better than any brochure.
- The schedule of service charges for the past few years.
- Any notices of major works or special assessments already approved or under discussion.
- The building rules, covering pets, subletting, short-term rentals, and renovations.
A real scenario
An investor found a well-priced two-bedroom in an older block. The unit was renovated and move-in ready, so the temptation was to skip the paperwork. Reading the meeting minutes changed everything: owners had voted three months earlier to replace both lifts and repair the facade, with a special assessment of several thousand per unit due the following year. The reserve fund could not cover it. That cost was not in the price, not in the listing, and not visible during the viewing. Armed with the minutes, the investor negotiated the price down to absorb the coming bill, instead of discovering it after completion.
Restrictions that can break your investment case
If your plan is to rent the unit out, check the building rules before anything else. Some buildings ban or limit subletting. Many now restrict short-term rentals. If your entire return depends on renting and the rules forbid your rental model, the deal is dead regardless of price. Confirm this in writing, not from the agent’s reassurance.
Common mistakes and how to fix them
- Inspecting the unit, ignoring the building. Fix: give the shared building the same scrutiny as the private space.
- Skipping the meeting minutes. Fix: read the last two or three sets before offering.
- Assuming service charges are static. Fix: check the multi-year trend, not just today’s figure.
- Not asking about the reserve fund. Fix: request the balance and upcoming works schedule in writing.
- Overlooking rental restrictions. Fix: confirm subletting and short-term rules before you commit.
Action steps
- Request management accounts and the reserve fund balance in writing.
- Read the last two to three owners’ meeting minutes end to end.
- Get the service-charge history and check the trend.
- Confirm any planned major works or special assessments.
- Verify the building’s rules match your rental or use plan.
- Price any coming repair bill into your offer.
Conclusion
A resale apartment lets you see the physical asset, which lulls buyers into skipping the paperwork where the real risks hide. Do the opposite: inspect the unit quickly and the building’s finances slowly. Your next step: for any resale you are considering, request the reserve fund balance and the last set of meeting minutes before you make an offer.
Frequently asked questions
What is a sinking fund and why does it matter?
It is the shared savings pool for major building repairs. A well-funded reserve means big repairs are already paid for; an empty one means those costs will hit you later as a special assessment. It is one of the strongest signals of a building’s financial health.
Can I really ask for the meeting minutes as a buyer?
Yes. In most jurisdictions, a serious buyer or their lawyer can request management accounts, the reserve balance, and recent minutes as part of conveyancing. If the seller or management refuses, treat that resistance as a warning sign.
How do I know if service charges are too high?
Compare them to similar buildings nearby and look at the trend over several years. High charges are not automatically bad if the building is well-run and well-maintained. Charges rising fast, or a low charge sitting on top of an empty reserve, are the real concerns.
What if the building bans subletting?
Then it cannot support a buy-to-let strategy, no matter how good the price. Always confirm the rules on subletting and short-term rentals in writing before you commit, because they can invalidate your entire investment plan.
