Housing affordability and the hidden maintenance costs nobody warns first-time buyers about
The housing affordability debate in Australia focuses almost entirely on house prices.
Deposit barriers, stamp duty, mortgage affordability, auction liquidation rates: these are the metrics that dominate the conversation. But for a growing number of first-time buyers venturing into Melbourne’s eastern suburbs to gain a foothold in the market, the purchase price is just the beginning of the financial story. Thereafter, the ongoing cost of maintaining an old house in a suburb such as Kilsyth, Mooroolbark or Ferntree Gully is a fact that receives almost no attention in the public debate about how much it actually costs to own a house in this country.
This is not a matter of poor financial planning on the part of individual buyers. This is a structural gap in the information available to people entering the housing market for the first time, and it has real consequences for household budgets that are already under pressure.
Where first-time buyers land
Melbourne’s outer east has become one of the priority destinations for buyers who cannot compete in the inner and middle ring suburbs. Kilsyth, located at the base of the Dandenong Ranges, about 35 kilometers east of the CBD, is a representative example. The suburb offers relatively affordable housing by Melbourne standards, a strong sense of community and proximity to both the mountains and the Eastern Freeway corridor.
But housing stock tells a story that real estate listings often overlook. Much of Kilsyth was developed in the 1960s and 1970s, producing solid brick veneer houses built to the standards of the period on quarter-acre blocks. These homes have served their residents well for decades, but their basic infrastructure, plumbing, electrical, drainage, insulation and roofing, are now 50 to 60 years old. This age brings with it a maintenance profile that bears no resemblance to the near-zero maintenance costs of a new-build property.
The plumbing bill that no one budgeted for
Of all the hidden costs that baffle new homeowners in suburbs like Kilsyth, plumbing always ranks among the biggest and least expected. Galvanized steel water pipes, standard in homes from this period onwards, corrode internally over decades, gradually restricting water flow until they fail completely. The original clay sewer pipes are cracking, slipping from their joints and allowing tree roots to seep through the mature gardens that surround them. Hot water systems installed during previous renovations may be operating for years beyond their intended service life, consuming more energy and providing less reliable performance with each passing winter.
These are not cosmetic problems that can be postponed indefinitely. A burst pipe flooded a house. The collapse of the sewer line makes the bathroom unusable. A failing hot water system in the middle of a Kilsyth winter is no small inconvenience for a family with children.

Lexity Plumbing & Electrical is dual plumbing and electrical licensed and serves Kilsyth and the surrounding outer eastern suburbs with fixed upfront pricing, a $0 call-out charge during business hours and a Lifetime Workmanship Warranty. A thorough evaluation during the first year of ownership identifies what is wearing out gracefully and what is approaching failure, allowing the homeowner to budget for replacements on their own timeline rather than being forced into emergency expenses.
A policy blind spot
The lack of meaningful maintenance cost disclosure in the property transaction process is a policy gap that disproportionately affects first-time and low-income buyers. Wealthier buyers can cover unexpected repair costs without financial stress. A first-time buyer in Kilsyth, struggling to cover the deposit, committing to a mortgage at the limit of serviceability and having minimal remaining savings, is in a fundamentally different position when a $6,000 hot water system replacement or $4,000 sewer repair is undertaken within the first year.
These costs do not appear in any affordability calculators. They are not taken into account in credit evaluations. It is not disclosed by sellers except in cases where a known defect triggers a legal obligation. In most cases, they are not covered by home insurance because they result from gradual deterioration rather than sudden events.
For a housing policy conversation that truly grapples with affordability, the cost of ownership needs to be alongside the cost of entry. A house that is cheap to buy but expensive to maintain is not actually affordable. This is a deferred cost structure that shifts the financial burden from the point of purchase to the early years of ownership, precisely the period when the buyer is least equipped to meet that burden.
What does consumer protection not cover?
First-time shoppers in Victoria are entitled to certain consumer protections regarding the purchasing process and product. Australian Securities and Investments Commission (ASIC) Provides comprehensive guidance on mortgage products, lender obligations and financial risks associated with property investment. These protections serve an important function in ensuring that buyers are not misled about the financial products they enter into.
But what no regulatory framework has adequately addressed is the information gap between buying a home and understanding how much it will cost to maintain it. Pre-purchase building inspections, which are optional rather than mandatory in Victoria, provide a snapshot of visible defects but rarely include detailed assessment of plumbing condition, electrical compatibility or drainage integrity. A building inspector may find that the hot water system is outdated but that it is not possible for him to pressure test the water supply, camera-inspect the sewer line, or check that the electrical panel meets current safety standards.
As a result, buyers are making the largest financial commitment of their lives with an incomplete picture of the asset’s condition and no realistic estimate of the maintenance costs they will incur in the first five to ten years of ownership.
What can buyers do now?
Until policy settings change, individual buyers need to protect themselves. For anyone buying in Melbourne’s outer east, particularly suburbs with older housing stock such as Kilsyth, Croydon, Bayswater or Mooroolbark, three practical steps reduce the risk of financial surprise.
Firstly, have a specialist plumbing and electrical inspection carried out in addition to the standard building inspection, ideally before occupation or within the first few months of ownership. The cost is modest for the clarity it provides.
Second, create a dedicated maintenance fund from the very beginning. Setting aside even a small amount each month creates a buffer that prevents a single repair from turning into a financial crisis.
Third, establish a relationship with a licensed local tradesman before you need it in a hurry. Emergency calls in the middle of the night cost more than scheduled work during business hours, and a tradesman who already knows your property and their systems can diagnose and resolve problems quicker.
The housing affordability debate in Australia will remain incomplete as long as it considers purchase price as the finish line. For thousands of first-time homeowners in suburbs like Kilsyth each year, the true cost of homeownership only begins when the keys are handed over.
