Home maintenance is more complex — and more interesting — than most people expect. It is one of the main causes of conflict between landlords and tenants, because their incentives are fundamentally misaligned: one party pays, the other benefits. The same friction can arise in co-owned properties, where the parties disagree on whether to do a quick cheap fix or a more durable long-term repair, or where skill levels differ.
This article covers three things: how maintenance responsibility works under Passive Partnerships, why we use 0.75% of property value in our calculations, and why owner-occupied properties are typically both cheaper and better maintained than equivalent rentals.
How Passive Partnerships handles maintenance
A key feature of Passive Partnerships is that there is one decision-maker responsible for all maintenance and improvements: the Resident Owner. The Passive Owner takes no part in maintenance decisions and bears none of the costs.
This may not seem fair at first, but fairness is built into the model. Any value added through good maintenance flows to the Resident Owner, because the Passive Owner's return is linked to the market average and not to the specific condition of the property. Conversely, if the Resident Owner neglects maintenance, they bear that cost too: a deteriorating property reduces their equity relative to the market, while the Passive Owner remains insulated. This creates strong, clean incentives for the person who lives in the property to maintain it well — the opposite of the landlord/tenant dynamic.
How and why we set the maintenance percentage at 0.75% of property value
This figure feeds directly into the Occupancy Rate that the Resident Owner pays the Passive Owner. It reduces that fee to account for the fact that the Resident Owner pays all maintenance and improvement costs. See how the occupancy rate is calculated →
Maintenance can cost between 0.5% and 3% of property value per year depending on the state and type of property. In the PP model we allow a fixed 0.75%, for a number of reasons:
- It is a simple rule that can be applied universally — no negotiation and debate for each different property.
- Any difference between properties in the state of repair needed is typically already accounted for in the price paid for the property. You pay a lot for a well-maintained, low-maintenance property and much less for one needing lots of repairs.
- In the Passive Partnership model the homeowner already gets even more savings than the investor, so setting this figure slightly lower seems a fair compromise. See the full breakdown of savings on both sides →
- If the maintenance allocation were any higher, the Occupancy Rate would look ridiculously low. Given how high rent seems to most people, they are typically quite surprised just how little cash investors actually make. The only way to make the cash flow work is sometimes to defer maintenance, which is not good for either party long term.
Why it costs more to maintain a rental than an owner-occupied property
It is typically estimated that owner-occupied properties cost 15–30% less to maintain than equivalent rentals. The main reason is structural: landlords face a set of mandatory costs and obligations that owner-occupiers simply do not encounter.
Healthy Homes Standards compliance (insulation, heating, ventilation, moisture/drainage, draught stopping) is a landlord-only legal obligation under the Residential Tenancies Act, with ongoing documentation requirements. Landlords must also ensure smoke alarms are tested and maintained, with penalties up to $7,200 for non-compliance — and best practice is to outsource this to a qualified company rather than DIY, another cost an owner-occupier does not face at all.
Maintenance coordination markup: when a property manager arranges a tradesperson, they typically charge a coordination fee of 5–15% on top of the tradesperson's invoice, adding roughly $200–$500 a year that has no equivalent for a self-managing owner-occupier.
End-of-tenancy cleaning and turnover prep: NZ tenancy law requires the property be left "reasonably clean and reasonably tidy" at each change of tenant, which drives a repaint/clean/repair cycle every tenancy that an owner-occupied home never goes through.
DIY and self-management: most owner-occupiers don't pay a tradesperson to clean their gutters, check smoke alarms, or replace a broken heat pump remote — tasks that are straightforward when you live in the property. For landlords, each becomes a paid job. For owner-occupiers with serious DIY skills the savings can be substantial, which explains much of the wide 0.5–3% annual range.
The behavioural dimension — owner-occupiers spot and respond to problems faster — is covered in the next section, and compounds all the costs above.
Why rental properties tend to be in worse condition
Beyond the structural costs above, several interconnected reasons explain why rentals tend to end up in worse physical condition than owner-occupied homes of similar age and location.
Incentive alignment
Owner-occupiers directly benefit from maintaining their property — it preserves and grows their own wealth. A landlord maintaining a rental is spending money to protect an asset they don't live in, while the person who lives in it has no financial stake in its condition. The incentives simply point in different directions.
The tenancy churn problem
The previous section covered the direct costs of tenancy changeovers. The cumulative physical effect is equally significant: multiple tenancies produce wear that continuous owner-occupier care never generates. A property lived in by one careful owner for 10 years typically looks very different from one that has had five or six tenancies in the same period.
Day-to-day attention — and the cost of delay
Owner-occupiers notice problems as they arise and have a strong personal incentive to fix them quickly — a slow drip, a sticking door, a patch of damp. Small problems caught early are cheap; the same problems left for weeks become expensive. In a rental, this chain breaks at two points: tenants often do not report minor issues (it doesn't feel like their problem), and landlords, particularly those using property managers, are often slower to respond. Issues an owner-occupier would address in a day can go unresolved for weeks in a rental.
Financial pressure on landlords
NZ landlords typically carry significant mortgage debt on investment properties. During periods of high interest rates or thin yields, maintenance spending is the easiest cost to defer. Owner-occupiers don't have the same pressure — they're maintaining their home, not managing a business margin.
Meth and damage risk
The rental sector carries a genuine, if sometimes overstated, risk of property damage, meth contamination, and deliberate neglect by a small number of tenants. This creates a two-tier market where the most pristine properties exit the rental pool as owners choose to sell or occupy rather than risk damage, leaving a skewed sample in the rental stock.
The overall picture — lower costs and better condition — is well supported by insurance claims data, maintenance cost surveys, and property inspection records. For many property types and age groups, the 15–30% cost differential is likely conservative.
Summary
Passive Partnerships reduces maintenance costs for two compounding reasons. First, it removes the structural overhead unique to rental properties: compliance obligations, management markups, professional services that owner-occupiers handle themselves, and the repaint/repair cycle at each tenancy changeover. Second, it restores the owner-occupier incentive — the person who lives in the property bears the full financial consequence of how well it is maintained, which produces better outcomes for everyone.
