Why is my rent going up? The bigger picture

Many tenants wonder whether a rent increase is justified — or just greed. The honest answer is: it's usually a mix. Most landlords face genuine cost pressures they don't control, but a rent increase isn't automatically justified just because those pressures exist. This page explains both sides, so you can have an informed conversation and decide whether to seek advice.

Explanations on this page are evergreen — the mechanisms don't change. Figures (interest rate, CPI, vacancy) are drawn from official sources and updated when the ETL runs. Last reviewed: 27 August 2026. This page is general information only, not financial or legal advice.

What drives rent increases

Eight common cost pressures landlords cite — tap each to expand. Links to official figures are included where available.

Interest rates & mortgage repayments

This is the single biggest lever for most landlords. Most investment properties carry a loan. When the RBA raises the cash rate, variable mortgage repayments rise — often by hundreds of dollars a month on a typical investment loan. Many landlords pass some or all of that cost through in rent. Conversely, when the RBA cuts rates, those repayments fall.

Inflation (CPI)

The cost of maintenance, building materials, tradespeople, and services all rise with general inflation. A plumber costs more this year than last year; so does a coat of paint or a new hot water system. CPI also plays a direct role in Victoria's rent assessment process — it's one of the factors CAV weighs when reviewing whether an increase is excessive.

Land tax & council rates

Victorian investment property owners pay annual land tax to the State Revenue Office (SRO). Council rates are also paid annually. Both are holding costs that rise over time. Victoria has made several significant land tax changes in recent years — including a lowering of the threshold at which land tax applies and the introduction of a temporary COVID-related debt levy — meaning some landlords are paying substantially more than they were a few years ago.

Insurance premiums

Building insurance and landlord insurance premiums have risen sharply in recent years, partly due to natural disasters and climate-related risk increasing insurers' costs, particularly in flood, storm, and bushfire-prone areas. These are real, rising costs — though they vary greatly by property and location.

Supply, demand & vacancy rates

When fewer rentals are available (low vacancy), landlords have more pricing power — simply because more tenants are competing for fewer homes. Victoria's rental market has been tight in recent years, driven by population growth and a shortfall in new construction. This is a market force, not a specific cost — but it's real, and it affects what landlords believe the market will bear.

Maintenance, compliance & minimum standards

Victoria has progressively introduced rental minimum standards — covering heating, insulation, draught-proofing, and other essentials. Gas and electrical safety checks are required at specific intervals. Energy-efficiency upgrades have also been phased in. These requirements protect tenants' safety and comfort, but they also impose real, ongoing costs on landlords. Routine maintenance — plumbing, appliances, structural repairs — is always an ongoing expense.

Property management & turnover costs

Landlords who use a real estate agent typically pay management fees (a percentage of weekly rent) and a letting fee (charged each time a new tenant is found). When a tenancy ends, there are also cleaning, advertising, and re-letting costs. These are real overheads — and in a market where turnover is frequent, they add up.

Tax settings (negative gearing)

The 2026–27 Federal Budget announced changes to negative gearing rules for established properties purchased after 7:30pm AEST on 12 May 2026. However, properties owned before that date are grandfathered — the current rules continue to apply for as long as the current landlord owns the property. The changes also don't take effect until 1 July 2027 at the earliest, and are still subject to legislation. For most current landlords, this is not a new cost.

What does a typical landlord's cost look like?

The diagram below is illustrative only — it shows the type of costs involved, not any specific property or landlord. Proportions vary enormously depending on the loan size, property type, location, and how the property is managed.

⚠ Illustrative only — not a claim about any specific landlord or increase

  • Mortgage interest (~52%)
  • Maintenance & repairs (~14%)
  • Land tax & council rates (~13%)
  • Insurance (~10%)
  • Management fees (~7%)
  • Other (~4%)

Based on illustrative figures for a typical Victorian investment property with a mortgage. Properties owned outright (no mortgage) have a very different cost profile. This diagram does not reflect any specific landlord's costs.

The other side of the picture

Cost pressures don't automatically justify any specific increase

These are legitimate pressures — but landlords aren't required to prove a specific cost increase before raising rent. In practice, many rent increases are also shaped by what the market will bear. A tight rental market gives landlords pricing power that has nothing to do with their individual costs.

That's exactly why Victoria has a free excessive-rent assessment

The CAV assessment doesn't ask about the landlord's personal finances. It weighs the local rental market, the property's size and condition, its location, and a range of other objective factors — so the assessment reflects what's fair for this property in this area, not just whether a landlord's costs have risen.

Understanding this helps you decide what to do next

Knowing these drivers can help you have a more informed conversation with your landlord or agent, and it helps you understand the context — but it doesn't mean you should simply accept an increase. If you think the increase may be excessive, the free CAV assessment exists precisely for this.

Free next step: request a CAV assessment

If you think your increase may be excessive, apply to Consumer Affairs Victoria for a free rent assessment. You must apply within 30 days of receiving the written notice of increase.
