Insurance — every position, before you buy and while you hold.
Most owners hold one policy and call it covered. A property run as a business carries insurance in several positions — and the most expensive mistake is the cover that wasn't in place before the hammer fell.
A business insures more than its building. It insures the income, the people the income depends on, and the liabilities it carries to the public and its customers. A rental property is no different — but most owners hold a single policy bought once, never reviewed, and never tested against what it would actually have to pay out. This is the plain-English map: the positions cover sits in, the check you do beforeyou commit, and the trap that quietly halves a claim. It isn't insurance advice — it's the set of questions to take to a licensed broker so the cover lands on your real exposure, not a guessed one.
“The cheapest insurance mistake is paying for cover you didn't need. The most expensive is discovering, after the event, that the cover you had didn't apply.”
Insurance sits in more than one position
"Am I insured?" is the wrong question. The business question is "where am I covered, and where am I exposed?" A property run as a business carries cover across several positions — and most owners hold two or three of them and have never thought about the rest.
Building / property
The structure itself, against fire, storm, impact and the like. The two traps live here: whether you're insured for total replacement (rebuild whatever it costs) or a fixed sum insured (a number you nominated, which is usually too low), and whether the perils you actually face — flood especially — are covered, excluded, or an optional extra you didn't tick.
Landlord
The cover a building policy doesn't include: loss of rent if the place becomes untenantable, tenant-caused or malicious damage, and rent default. This is the difference between an owner-occupier policy and one built for a property that earns.
Public liability
Someone is injured on the property and you're found responsible. Often bundled into landlord or strata cover, but worth confirming the limit — it's the position with the largest tail.
Short-stay
If you let on Airbnb-style platforms, a standard landlord policy frequently won't respond. Short-stay grosses more and is exposed differently; the cover has to match the use.
Strata / body-corporate adequacy
For a unit, the building is insured by the body corporate — but is it insured for enough? An under-insured scheme means a shortfall that lands on every owner as a special levy. Reading the certificate of currency and the valuation is part of your due diligence, not theirs.
Income (owner)
Income protection pays you if you can't work. The rent rarely covers the loan on its own; the position that actually keeps the property afloat is often your own income, and that's the one most owners never insure.
Family
Life cover and TPD (Total and Permanent Disability) so the people you leave can keep paying the loan — or clear it — instead of being forced to sell into a bad market at the worst possible moment.
A note on the loan: lenders mortgage insurance (LMI) protects the lender, not you. It is not a substitute for any of the cover above.
The check you do before you commit — not after
This is the one people skip, and it's the most expensive. In Australia, the risk usually passes to you at the fall of the hammer (or on exchange) — which means building insurance has to be arranged before you bid, not after settlement. Buy at auction without cover bound and you own an uninsured asset from the moment the hammer drops.
In a flood, bushfire or earthquake zone the question goes one step further: not "what will cover cost?" but "canI insure this at all?" Insurers are retreating from high-risk locations, and a property that is hard or impossible to insure is hard to let, hard to finance, and hard to sell. A declined quote, or one loaded with exclusions, is not a hurdle to push through — it's a buy signal in its own right. Insurability is due diligence. Check it before you're committed, while walking away is still free.
“Insurability isn't paperwork for after settlement. In a hazard zone, it's the buy-or-walk decision itself.”
Australia — the pieces that matter most here
Sum insured vs total replacement
Most Australian home policies are sum insured — you nominate a rebuild figure. Set it from the purchase price or an old estimate and you'll almost certainly be under, because rebuild cost (demolition, current materials, current labour, code upgrades) is not market value. Total-replacement cover removes the guesswork but isn't always offered.
The under-insurance / co-insurance clawback
If you're insured for materially less than the rebuild cost, many policies reduce even a partial claim in proportion. Insured for 70% of what it would cost to rebuild, and a $100k partial loss can be settled at a fraction of that. The trap isn't a total loss you can see coming — it's the partial claim you thought you were covered for.
Flood is its own peril
Flood is frequently an opt-in or an outright exclusion, separate from storm. Many owners in flood-mapped areas discover the gap only at claim time. Check the definition, not just the box.
Northern Australia
Cyclone-exposed regions sit under the Cyclone Reinsurance Pool, which affects pricing and availability. Worth understanding before you buy in the north.
New Zealand — the pieces that matter most here
EQC / Toka Tū Ake sits under your private policy
Natural-disaster cover (earthquake, and certain land damage) comes through the public scheme up to a cap — currently $300,000 plus GST for the building — and your private policy covers above that. You need to know your building's sum insured and whether you're covered for the gap between the cap and the real rebuild cost.
Sum insured is the norm
Like Australia, NZ home cover is overwhelmingly sum insured rather than total replacement — so the same under-insurance trap applies. Get the rebuild figure right, and revisit it as building costs move.
Flood and coastal-inundation risk-pricing
Insurers increasingly price flood and coastal risk property-by-property, and the council LIM (Land Information Memorandum) lists known hazards. Check the LIM before you buy — the hazard line is also an insurability line.
While you hold — cover is a position you manage, not a set-and-forget
Premiums and exclusions drift. A policy that fit five years ago may now be under-insured (because rebuild costs rose) or quietly narrowed (because the insurer added an exclusion at renewal you didn't read). Two habits a business owner keeps that a passive owner doesn't: review the sum insured and the exclusions at every renewal, and keep the current certificate of currencyin the property file — it's the proof a buyer's solicitor, a lender, or a body corporate will ask for, and a sale-ready file has it to hand.
And remember the link most owners miss: compliance and insurance are the same conversation. An unapproved structure or a missing smoke alarm can void a claim on an otherwise valid policy. (See Landlord compliance & smoke alarms for the gates that keep your cover live.)
The questions worth taking to a broker
- Am I insured for total replacement, or a sum insured I nominated — and when was that figure last checked against real rebuild cost?
- If I made a partial claim tomorrow, would under-insurance reduce the payout?
- Is flood (and, where relevant, cyclone or earthquake) covered, excluded, or an optional extra — and which have I actually got?
- Do I hold landlord cover (loss of rent, tenant damage, rent default) on top of building cover — or just building?
- If it's a unit: is the body corporate's cover adequate, and have I seen the certificate of currency and the valuation?
- Is my income insured (income protection), and is the loan covered by life/TPD if something happens to me?
- For a purchase: from exactly what moment does risk pass to me, and is cover bound from that moment?
- Has anything about the property — an alteration, a use change, a compliance gap — changed what my policy will actually pay?
Insurance is downstream of one bigger question: is the property itself sound enough, in a location insurable enough, to be worth holding? Cover protects the asset; the prior question is whether the asset is doing what it was supposed to. Most owners have never laid that out — and the insurance conversation lands very differently once they have.

Before You Hold is the diagnostic course for 1–3-property owners in AU and NZ. Eight modules, your real numbers, the threats and the cover positions laid out — and the questions worth asking the people you pay, including the broker. Insurance decisions land harder when you know what the property is actually doing.
