Renovate or Relocate? How to Finance a Major Reno in the St George Area

7 min read · by Ugur, demir.loans

A lot of the houses across the St George area sit on good land with tired bones: solid brick, generous blocks, dated layouts. With borrowing capacities tight and Sydney upgrade prices what they are, more owners are choosing to fix what they have rather than sell and buy again. The finance side just works differently to a normal home loan, and getting it wrong causes more delays than the renovation itself.

Why extend instead of move

Selling and buying again means stamp duty on the next place, agent fees on this one, and a scramble to buy in the same tight market you're selling into. If the block, the street and the bones of the house are already right, a renovation converts a chunk of that transaction cost into square metres and a kitchen you actually chose. It only stacks up if the finance is structured for the size of the job, which is where the two paths split.

The small end: equity release

A $40,000 kitchen, a bathroom or two, new floors: this is usually a straightforward equity release or a top-up on your existing home loan. The bank orders a valuation, confirms there's enough equity, and once it settles the money is yours to draw down and spend as the job progresses. No inspections of the build, no staged approvals. It's fast because the bank isn't taking on construction risk, just lending against equity that's already there.

The big end: a construction loan

A $400,000 second-storey addition is a different product entirely. The bank isn't just lending against today's value, it's lending against a house that doesn't exist yet, so it releases funds in stages as the builder completes them: slab, frame, lock-up, fit-out, completion. Each stage is inspected before the next payment goes out. You pay interest only on what's been drawn so far, which keeps repayments lower while the build is underway, but it means more paperwork upfront and a stricter approval process than a straight equity top-up.

How the bank values a project that isn't finished

Construction lending is assessed on an "as if complete" valuation: a registered valuer estimates what the property will be worth once the addition is built, using the plans and specifications, not what it's worth as a half-finished site. That end value is what determines how much the bank will lend against the project, alongside your income and existing equity. It's a different number to the valuation you'd get on the house as it stands today, and it's the one that actually matters for a construction loan.

Why a fixed-price contract is mandatory

For anything past minor cosmetic work, lenders require a fixed-price building contract from a licensed builder before they'll approve a construction loan, not a rough quote or a cost-plus arrangement. It protects the bank from a project that blows out mid-build and can't be finished, and it protects you the same way: a fixed price means you know the number you're borrowing against is the number you'll actually pay, provisional sums and variations aside. A builder unwilling to fix the price is worth treating as a warning sign in its own right.

What to have ready before you apply

Council-approved or complying development plans for the works.
A fixed-price building contract from a licensed builder, itemising provisional sums.
The builder's licence details and current insurances.
A recent rates notice and, if the loan is being topped up, your current mortgage statement.
A realistic contingency, most lenders and quantity surveyors expect at least 10 to 15 percent of the contract price held in reserve.

Questions, answered

Can I act as owner-builder to save money?

Some lenders allow it for smaller jobs, but many won't finance an owner-builder construction loan at all, and those that do apply tighter conditions and lower borrowing limits because the risk sits more heavily with you. Check this before you commit to the approach, not after.

What happens if the builder wants a variation mid-project?

Variations are common and normal, but they sit outside the fixed-price contract and need to be funded separately, either from your contingency or an increase to the facility. Get every variation in writing with its cost before work starts on it.

Do I need a construction loan for a $40,000 kitchen renovation?

Usually not. Jobs of that size are typically funded through an equity release or redraw against your existing loan rather than a staged construction facility, which keeps the process simpler and faster.

How long does construction loan approval take compared to a normal home loan?

Longer. Beyond the usual income and equity checks, the lender needs the plans, the fixed-price contract and often a specific valuation before approval, so it pays to start the finance conversation while the plans are still being finalised, not once the builder is ready to start.
