How to Budget for Maintenance and Repairs on an Investment Property

Owning an investment property can be a great long-term investment, but it also comes with ongoing costs that landlords need to plan for. One of the most important and sometimes unpredictable expenses is property maintenance and repairs.

From a leaking tap or broken appliance to air-conditioning issues, plumbing problems or unexpected storm damage, maintenance costs can quickly add up if you’re not prepared.

The good news? A little planning can help you avoid being caught off guard and keep your investment property in good condition.

Here’s how to create a practical maintenance budget for your rental property.

Why you need a maintenance budget

One of the biggest mistakes property investors can make is budgeting only for their regular expenses, such as mortgage repayments, insurance, rates and property management fees.

Maintenance is another ongoing cost of owning a rental property. In Perth, landlords are also responsible for ensuring their rental property is maintained and that necessary repairs are addressed within the required timeframes.

Putting money aside specifically for maintenance means you can deal with unexpected repairs without having to scramble for funds.

It can also help you avoid delaying smaller problems that could eventually turn into much more expensive repairs.

For example, a small roof leak may seem manageable at first, but leaving it unattended could lead to water damage, mould or damage to ceilings and flooring.

How much should you budget for maintenance?

There is no single amount that will work for every investment property. Your maintenance budget should take into account the property's age, condition, size, location and the age of major appliances and systems. For an older property, it may make sense to set aside more.

As a general rule of thumb, consider having a cash buffer of 1 to 3 months worth of rental income set aside for maintenance and repairs. 

The important thing is to have a financial buffer rather than assuming maintenance costs will always be minimal.

Separate routine maintenance from major repairs

It can help to divide your maintenance budget into two categories.

1. Routine maintenance

These are the smaller and more predictable expenses involved in keeping the property in good condition.

They may include:

• Gardening and outdoor maintenance
• Gutter cleaning
• Minor plumbing repairs
• Replacing worn fixtures
• Smoke alarm servicing
• Air-conditioning maintenance
• Minor electrical repairs
• Pest control
• Fixing doors, locks and handles
• General wear and tear

Regular maintenance may seem like an unnecessary expense when everything is working properly, but preventative maintenance can help reduce the likelihood of larger problems later.

2. Major repairs and replacements

These expenses are less frequent but can have a much bigger impact on your cash flow.

Examples include:

• Replacing an air conditioner
• Replacing a hot water system
• Major plumbing repairs
• Roof repairs
• Replacing appliances
• Fence repairs
• Repainting
• Flooring or carpet replacement
• Significant electrical work
• Repairs following storms or other unexpected events

Consider creating a separate savings buffer for these larger expenses so that a major repair does not completely disrupt your investment budget.

Consider the age of your property

The age and condition of your property should influence how much you set aside.

A newer property may require fewer major repairs in the short term, although it can still experience unexpected issues. An older property, on the other hand, may have ageing plumbing, electrical systems, roofing, appliances, air conditioning and other fixtures that are more likely to require attention.

Before setting your annual budget, take stock of the property's major components.

Ask yourself:

• How old is the roof?
• How old is the hot water system?
• Are the air conditioners nearing the end of their expected lifespan?
• How old are the major appliances?
• Does the property have a pool?
• Are the fences and gates in good condition?
• Does the property have a large garden or extensive landscaping?
• Are there any existing maintenance issues?

Knowing what could potentially need replacing allows you to plan ahead rather than treating every repair as an emergency.

Don't forget seasonal maintenance

Some maintenance expenses are easier to anticipate because they are seasonal.

For Perth properties, landlords may want to consider maintenance such as:

Before winter:

• Checking/clearing gutters and downpipes
• Inspecting the roof for damage
• Checking for leaks
• Servicing heating systems
• Checking drainage around the property

Before summer:

• Servicing air conditioning
• Checking outdoor areas
• Inspecting fences and gates
• Checking/fixing irrigation systems
• Managing trees and overgrown vegetation

Regular inspections can help identify smaller issues before they become expensive problems.

Keep a maintenance reserve

Instead of paying for repairs from your everyday household or investment cash flow, consider maintaining a dedicated maintenance reserve.

You could contribute to it monthly or after receiving rental income.

For example, if you decide your annual maintenance allowance is $6,000, setting aside approximately $500 per month gives you a dedicated pool of funds for repairs and maintenance.

If you don't use the full amount during the year, the balance can remain available for future repairs.

This approach can be particularly useful because maintenance costs are rarely consistent from one year to the next.

Don't delay necessary repairs

It can be tempting to postpone a repair because it isn't convenient or because the cost seems too high.

However, delaying maintenance can sometimes make the problem worse.

A leaking pipe, damaged roof or faulty appliance may cause additional damage if it isn't addressed promptly. Taking care of problems early can protect both your property and your cash flow in the long run.

Keep records of your maintenance expenses

Good record-keeping is another important part of managing an investment property.

Keep copies of:

• Invoices
• Receipts
• Maintenance requests
• Inspection reports
• Quotes
• Contractor details
• Repair dates
• Appliance warranties
• Maintenance and servicing records

These records can help you monitor how much you are spending on the property and identify recurring problems.

They may also be important when discussing expenses with your accountant. The Australian Taxation Office distinguishes between repairs and maintenance and other types of property expenditure, so it's important to get professional tax advice about the treatment of specific expenses.

Unexpected repairs are part of owning an investment property, but they don't have to become a financial headache.

By setting aside money regularly, keeping track of your property's condition, carrying out preventative maintenance and working with reliable professionals, you can be better prepared when something inevitably needs fixing.

A well-maintained property can also help provide a better experience for tenants while protecting the long-term value of your investment.
