Holding Costs Explained for Property Buyers
Holding costs are the ongoing expenses you pay to own a property — including mortgage repayments, rates, insurance, and maintenance — separate from what you paid to buy it.
What Do Holding Costs Mean?
Holding costs are the regular expenses that come with owning a property from settlement date onwards. They include your mortgage repayments, council rates, water rates, landlord or home insurance, strata levies if applicable, and any ongoing maintenance or property management fees. These costs continue regardless of whether the property is generating rental income or sitting empty.
Buyers typically encounter holding costs in two situations: when weighing up whether a purchase is financially sustainable over the long term, and when an investment property sits vacant between tenants. In both cases, the gap between expected income and actual costs can catch buyers off guard if they have not done the numbers carefully in advance.
The real-world implication is straightforward: the longer you hold a property, the more these costs compound. A property that generates modest rental income may still produce a cash flow shortfall each week once rates, insurance, and maintenance are factored in. Understanding your holding costs helps you budget accurately and avoid financial stress during the ownership period.
Why This Matters for Buyers
Holding costs directly affect how long you can afford to keep a property — particularly if you are waiting for the right time to sell, navigating a vacancy period, or carrying a property through a renovation. Buyers who underestimate these costs can find themselves under pressure to sell at the wrong time, simply because they cannot cover the ongoing expenses.
For investors, holding costs determine whether a property is negatively, neutrally, or positively geared. A negatively geared property costs more to hold than it earns in rent. This is a deliberate strategy for some buyers who are banking on capital growth to offset the shortfall, but it requires genuine cash flow capacity to sustain month after month.
For owner-occupiers, holding costs shape how much of your monthly income is committed to the property. Rates, insurance, and maintenance tend to increase over time, so what feels comfortable at purchase can become tighter as years pass. Building a buffer for these costs from the outset is good practice.
Timing decisions are also influenced by holding costs. If you are buying before selling your existing home, or bridging between two properties, the cost of holding two properties simultaneously can be significant. Running these numbers in advance — rather than discovering them mid-settlement — gives you more control over your decisions.
Common Mistakes Buyers Make
Holding costs are easy to underestimate because many of them are invisible at the point of purchase. These are the mistakes that tend to catch buyers out:
- Forgetting strata levies in investment calculations — For strata properties, quarterly levies can significantly reduce net income and are often left out of initial cash flow projections.
- Ignoring maintenance and vacancy allowances — Even well-maintained properties need repairs, and rental properties have vacancy periods. A buffer of around 10% of rental income is a reasonable starting point for these costs.
- Not accounting for land tax — Investors who accumulate multiple properties can tip into land tax territory, adding a cost that was not present at the time of purchase.
- Underestimating insurance costs — Landlord insurance, building insurance, and contents insurance can collectively be a meaningful annual expense, particularly on older properties or in areas with flood or bushfire overlays.
- Failing to model the holding period — Buyers sometimes focus on the purchase price and projected sale price without modelling how much the property will cost to hold in between. The longer the intended hold, the more material this becomes.
How This Shows Up in the Illawarra
In the Illawarra, holding costs vary considerably depending on property type and location. Freestanding houses in suburbs like Figtree, Albion Park, or Dapto tend to have lower strata levies but higher maintenance costs compared with coastal apartments. A beachside unit in Wollongong or Thirroul will typically carry strata levies, building insurance managed through the owners corporation, and potentially higher water rates depending on the building's infrastructure.
Properties in coastal and escarpment-adjacent areas can also attract higher insurance premiums due to proximity to flood overlays, bushfire prone land classifications, or salt air corrosion — all factors that increase maintenance frequency and cost. Buyers purchasing in these areas should obtain insurance quotes before committing to a price, as the cost difference from more sheltered locations can be meaningful.
For investors, the rental vacancy rate in the Illawarra has historically been low by NSW standards, which reduces the expected cost of vacancy periods. That said, vacancy can still occur, particularly at certain price points or between tenancies, and budgeting for it remains sensible practice regardless of current market conditions.
Practical Takeaway
Before committing to any purchase, build a simple holding cost model that covers your expected monthly mortgage repayment, council and water rates, insurance, strata levies if applicable, property management fees for investment properties, and a maintenance buffer. Add these up to understand the real weekly or monthly cost of ownership — not just the repayment figure.
If you are buying an investment property, compare total holding costs against realistic rental income to understand whether you will have a cash flow shortfall and how large it might be. If you are buying as an owner-occupier, make sure the combined monthly cost of all holding items sits comfortably within your budget with room to absorb rate increases over time.
A buyers agent can help you run accurate holding cost estimates during the due diligence phase — before you make an offer, rather than after. If you would like help modelling the real cost of ownership for a property you are considering in the Illawarra, reach out to The Shoreline Agency.
Frequently Asked Questions
What are holding costs in property?
Holding costs are the ongoing expenses of owning a property — including mortgage repayments, council rates, water rates, insurance, strata levies, maintenance, and property management fees. They continue for as long as you own the property.
When do holding costs become relevant?
They are relevant from settlement day onwards. They also become especially important when you are comparing potential purchases, modelling an investment's profitability, or navigating a period when the property is not earning rental income.
Are holding costs the same for every property?
No. They vary by property type, location, and ownership situation. A strata unit carries levies that a freestanding house does not. An investment property carries management fees and vacancy risk that an owner-occupied home does not. The mix of costs is different for every property.
Are holding costs tax deductible for investors?
Many holding costs for investment properties are deductible — including interest on the loan, council rates, insurance, management fees, repairs, and maintenance. You should speak with a tax adviser or accountant to understand what applies to your specific situation.
Should first home buyers care about holding costs?
Yes. First home buyers sometimes focus entirely on the deposit and purchase price without modelling what the property will cost each month after settlement. Running these numbers before you buy helps you choose a property that is genuinely affordable to own, not just to purchase.
How do holding costs affect timing decisions?
If you are holding a property through a slow market while waiting to sell, holding costs accumulate every week. Understanding this helps you make more informed decisions about when to sell, what price you can hold out for, and whether carrying the property longer is financially worth it.
How do holding costs relate to the NSW buying process?
In NSW, costs like land tax, council rates, and strata levies are adjusted at settlement, so the outgoing owner pays up to the settlement date and you take over from there. Your conveyancer will calculate these adjustments. From that point, holding costs are your responsibility.
Can a buyers agent help with holding cost estimates?
Yes. A buyers agent can help you model realistic holding costs for any property you are considering, including rates, strata levies, insurance, and maintenance allowances — so you understand the full cost of ownership before you commit. The Shoreline Agency does this as part of the due diligence process for every purchase.
