Rate Cuts, Borrowing Power and the Build Cost Reality

The rate picture, plainly put

The easing cycle that began in early 2025 has now delivered meaningful reductions in the cash rate, and most lenders have passed the bulk of those cuts through to variable borrowers. For someone building their first home, that shift does matter. A lower rate translates directly into a higher loan the bank will consider serviceable, which in turn widens the range of house-and-land packages and custom builds within reach. That is the good news, and it is real.

The complication is that build costs have not fallen in step with rates. Trades remain tight across both South Australia and Victoria. Materials pricing has stabilised compared with the 2022 and 2023 spikes, but it has not retreated to pre-pandemic levels. A gain in borrowing capacity can quietly disappear if your builder's base price or a site-cost variation absorbs it.

What the numbers on the ground look like

Recent official land valuation data points to softening values in a number of suburban areas across both states, including some of the corridors that first-home builders typically target. A correction in land pricing, even a modest one, can make a genuine difference to the deposit equation. It also changes the negotiating dynamic when you are choosing between titled land and a later-release lot.

At the same time, separate reporting signals that new home construction faces its own cost pressures heading into 2027, with both supply-side and demand-side forces at play. First-home builders who are watching and waiting for conditions to become perfectly comfortable may find the calculation does not improve as much as they hope.

SA and Victoria are not the same market

This is worth stating directly. South Australian builders operate under a licensing and Home Building Contracts Fund framework that differs from the Victorian Building Authority registration and domestic building insurance requirements that apply in Victoria. Neither state makes the compliance side simple, but the documents you need, the warranty cover structure and the dispute pathways vary. If you are comparing builders across state lines, as some buyers in SA's south-east appear to be doing after growing frustrated with Victorian conditions, treat each contract as its own exercise.

The first-home owner incentives also diverge. Eligibility thresholds, grant amounts and stamp duty concession structures are set independently by each state government and are subject to budget decisions. Check the current rules with your conveyancer or mortgage broker, not a website that may not have been updated since the last state budget.

The 7-star floor is not optional

Any new home contracted from October 2023 onward must meet the 7-star NatHERS minimum under NCC 2025. That applies everywhere in Australia, including both SA and Victoria. For first-home builders, the practical implication is that your working budget needs to absorb the insulation, glazing and sealing specification required to reach that threshold from the start. Builders who quote on a lower-spec shell and then add energy compliance as a variation later are creating a cost blow-out risk that you carry. Ask your builder specifically how their standard inclusions address the 7-star requirement, and get the answer in writing before you sign.

Choosing a package with your eyes open

BuildPilot currently lists 78 house-and-land packages across South Australia and 51 across Victoria, drawn from 12 partner builders and covering 804 home designs. That spread is useful because it lets you compare what different builders include at a given price point, which matters more than the headline figure. Site costs, flooring allowances, driveway and fencing contributions and energy compliance upgrades are the line items that most often surprise first-home builders after the contract is signed. Use every package comparison to force those costs into the open early.

What to watch

Keep an eye on whether any further rate movement comes through before the end of the year, and on how SA and Victorian state budgets adjust first-home incentive thresholds in response to land value shifts. In the growth corridors of both states, titled land supply in the next two quarters will tell you a great deal about whether softening values have further to go or whether stock tightens again quickly. If your finance pre-approval is current and your deposit is ready, the next 90 days may offer better entry conditions than the 90 days that follow.
