How It Works

What Is Renovation Refinancing and How Does It Work? Work?

Renovation refinancing means replacing your current home loan with a larger one, using the extra funds to pay for building work, extensions, or upgrades. You’re borrowing against the equity in your home—the difference between what it’s worth and what you owe.

The Process in Four Steps

  1. Valuation: Lender orders appraisal of current value plus as-if-complete value for larger projects
  2. Equity Calculation: Determine available equity (typically up to 80% LVR without LMI)
  3. Loan Structure: Match construction-draw or simple top-up to your project size and timeline
  4. Settlement: Funds released in stages or full amount, work begins

Example: $650k Home with $420k Loan

  • Property Value: $650,000
  • Current Loan: $420,000
  • 80% LVR Limit: $520,000
  • Available for Reno: $100,000

Choose Your Structure

Larger Projects (Over $50k):

  • Construction-draw structure
  • Funds in 3 stages
  • Matched to invoices & inspections
  • Interest only on advanced funds
  • Save $3k–$6k+ on 12-month build

Smaller Jobs (Under $50k):

  • Simple equity-release
  • Full amount at settlement
  • Work done in under 3 months
  • You manage builder payments
  • Fast process, no staged inspections

Why It Makes Sense

  • Lower Rates: Typically 2–4 percentage points lower than personal loans or credit cards
  • Review Everything: Perfect time to switch to a better rate, add offset, drop fees
  • Right Structure: Match the loan to your timeline and budget, not one-size-fits-all
  • Single Facility: Roll existing balance and renovation budget into one loan

Renovation Finance Options: Equity Release vs Construction Line vs Redraw

The three main ways lenders structure renovation funding are equity release (single advance), construction line (staged draws), and redraw from an existing facility. Each has different approval steps, interest treatment, and draw schedules. The table below shows which fits your project scope and timeline.

Finance TypeApproval ProcessInterest TreatmentDraw ScheduleTypical Use Case
Equity Release (single advance)Standard refi assessment; single valuation; funds at settlementInterest charged on full amount from day oneOne lump sum on settlement dayCosmetic upgrades under $50k, fast turnaround (kitchen, bathroom, paint, flooring)
Construction Line / Progress PaymentsRequires builder contract, council approval, progress-payment schedule, and staged inspectionsInterest only on funds advanced to date; capitalised or paid monthlyTypically 3–5 draws tied to build milestones (deposit, frame, lock-up, completion)Structural work over $50k, extensions, second storeys—anything taking 6+ months
Redraw from Existing LoanNo new application if facility has available redraw; instant access via online bankingInterest on redrawn amount; added to existing loan balanceWithdraw as needed, up to available redraw limitSmall jobs under $20k funded from ahead-of-schedule repayments; no new lender or valuation

Why this matters: on a $90,000 alfresco and pool cabana in Baldivis paid 30% / 40% / 30%, a construction line means you pay interest only on each draw as it's released—roughly $1,900 over a four-month build. Over a 10-month second-storey build, the gap between staged draws and a single advance left idle widens to $4,000–$6,000.

Most first-time renovation refinancers assume construction loans are only for new builds. They're not—any structural alteration over $50k qualifies, and about 60% of the lender panel offers them. Andy identifies which lenders do progress payments without extra rate loadings, and submits council and builder documentation upfront so there's no delay once the builder's ready to start.

What Most Borrowers Get Wrong About Renovation Draws

Most lenders will approve a refi to release equity—but they won’t advance the funds in stages as the work progresses. If your builder needs 30% up front, 40% mid-job, and 30% at completion, a standard equity-release loan hands you the full amount on day one, and you’re paying interest on money sitting idle in your offset. Around 60% of the renovation refi quotes I write involve staged-draw products or construction-line splits, yet most homeowners walk into the bank assuming it’s all or nothing. The difference over a 12-month build can be $3,000–$6,000 in wasted interest, and the bank won’t mention it because a single-advance loan is simpler for them to process.

The second mistake is underestimating how long council approval and builder availability push out the start date. You refinance in February, get the cash in March, but the builder can’t start until June because the DA is still pending. You’ve been paying interest on $80,000 for three months before a single nail is hammered. A construction line tied to actual progress eliminates that waste—the first draw doesn’t happen until the contract is signed and the deposit invoice is provided, often 4–8 weeks after loan settlement.

Finally, borrowers often forget that the as-if-complete valuation is conservative. If you’re adding a second storey in Rockingham and you think it’ll add $150,000 to the property value, the bank’s valuer might only recognise $110,000–$120,000 uplift because they use comparable sales of already completed two-storey homes nearby. That valuation gap can cap how much you’re allowed to borrow. Planning the scope with an eye to what actually moves the valuation needle—extra bedrooms and bathrooms beat cosmetic upgrades—means you don’t hit a borrowing ceiling halfway through design.

My advice: if the renovation budget is over $50k or the timeline is longer than 4 months, ask for a construction-line or split-facility quote upfront. If it’s under $50k and finishing in 6–10 weeks, a single-advance equity top-up is fine—just make sure you have offset capability so any unspent funds aren’t costing you interest. And always get a pre-approval valuation if you’re uncertain about property value; $250 spent on an independent val before you sign the builder contract can save months of pain.

How Andy Structures a Renovation Refi Card

From the first scope conversation to the final progress draw, Andy matches the loan to your builder's schedule.

Initial Conversation — Scope, Budget, Timeline

Andy asks what you’re building, what the builder or quantity surveyor quoted, and when you want to start. He’ll also ask about your current loan balance, property value estimate, and whether council approval is needed. This 15-minute call shapes the loan structure and lender shortlist.

Equity Calculation and Borrowing Capacity Check

Property value minus current loan equals available equity; the 80% LVR target minus existing debt equals your maximum top-up without LMI. Andy factors in your income, existing commitments, and whether you’re comfortable with a slightly higher LVR (85–90%) if the project justifies it. The output: a concrete borrowing limit and monthly repayment estimate.

Lender Selection and Product Match

Not all lenders do progress payments, and not all that do them process them quickly. Andy picks 2–3 lenders from his 40+ panel offering staged-draw construction lines (if needed), competitive variable or fixed rates, and fast turn-around on progress inspections—then explains the rate, fees, offset, and any discounts.

Lodgement With Builder Contract and Council Docs

For construction-line applications, the lender requires a signed builder contract (fixed-price preferred), council development approval (if structural), and sometimes a quantity surveyor’s cost breakdown. Andy coordinates the checklist so everything goes in together—no conditional approval sitting idle waiting for a missing DA number.

Valuation (Current and As-If-Complete)

The lender orders a current market valuation plus an ‘as-if-complete’ valuation assuming the renovation is finished. The gap between the two supports the equity release. If the valuation comes in low, Andy discusses options: smaller loan, higher LVR with LMI, or a co-borrower to boost capacity.

Approval, Settlement, First Draw

Once approved, the new loan settles—pays out your old lender, registers the new mortgage. For construction-line products, the first draw (the builder’s deposit, 20–30% of contract price) is released at settlement or shortly after, once the builder provides a tax invoice. You’re now paying interest only on that first advance.

Progress Inspections and Subsequent Draws

At each milestone (slab, frame, lock-up, completion), the builder invoices and the lender confirms the stage is complete. Andy liaises with the lender’s construction team to release the next payment within 5–10 business days, keeping the builder on schedule and your interest cost aligned with actual work done.

What Does Renovation Refinancing Cost?

Refinancing to fund a renovation attracts the same upfront costs as any refinance, with a few extras if you’re using a construction-line product. Here’s the typical breakdown for a Perth homeowner.

Cost ItemTypical RangeNotes
Valuation fee$300–$600Confirms current and ‘as-if-complete’ value; $700–$900 if a QS report is required
Lender application fee$0–$600Many majors charge $600; non-bank and specialist lenders often $400–$500
Legal / settlement fees$800–$1,500Drops to $200–$400 if you stay with your current lender and simply increase the limit
Discharge fee (old lender)$300–$500Sometimes waived after 2+ years with the lender
Construction-line setup fee$200–$400Only on staged-draw facilities; some lenders bundle it into the application fee
Progress inspection fees$150–$250 eachUsually 3–4 inspections; $600–$1,000 total, charged as they occur
LMI (only over 80% LVR)$4,000–$7,000One-time premium; avoid by keeping total borrowing under 80% of post-reno value
Typical total$2,000–$4,000Staged-draw reno; $1,500–$2,500 for a simple equity-release under $50k

Interest rates: variable renovation refinances in Perth typically sit at 5.7–6.4% (owner-occupier P&I; investor loans 0.3–0.5% higher). Construction lines sometimes carry a 0.1–0.2% loading during the draw period—Andy’s panel includes lenders that don’t load construction rates, keeping your cost the same as a standard refi. He walks you through every fee line by line before you commit, and can structure costs into the balance if paying upfront stretches cash flow during the build. For the bigger picture on savings, see how much you could save by refinancing.

Why Refinance for Your Renovation Instead of a Personal Loan or Credit Card

Funding a renovation through your home loan beats unsecured borrowing on rate, term, and tax treatment.

Home-Loan Rates, Not Unsecured Rates

Renovation refinancing typically sits at 5.5–6.5% variable, while personal loans run 8–14% and credit cards 12–22%. On a $60,000 kitchen reno, that gap saves you $1,800–$4,500 per year.

Longer Loan Term Lowers Monthly Repayments

A personal loan is capped at 5–7 years; a home loan spreads the cost over the remaining mortgage term (often 20–25 years). Repayments are far lower, freeing up cash flow for furniture, appliances, or the next stage.

Single Loan, One Repayment

Refinancing rolls the renovation cost into your mortgage—one loan account, one direct debit, one interest rate to track. No juggling a second loan statement or splitting repayments.

Tax Deductibility (Investment Properties)

If the property is tenanted, interest on the renovation portion is typically tax-deductible as a cost of earning rental income—personal-loan interest is not. Keep detailed records and confirm with your accountant.

Access to Better Loan Features

Add an offset account, switch to interest-only during the build if cash flow is tight, or lock part of the loan on a fixed rate. Personal loans rarely offer offset or redraw.

Renovation Refinancing Questions Perth Homeowners Ask

Yes, but expect discharge or break costs. Most lenders allow early exit, but variable loans under 12 months may attract a $500–$800 deferred establishment fee, and fixed loans incur break costs if you refinance before the fixed term ends (often $2,000–$10,000 depending on rate movement and remaining term). If your renovation can wait until month 13 or your fixed term expires, you’ll save those costs. If not, Andy can calculate whether the rate saving and equity access justify the early-exit fee—often they do if you’re dropping 0.8% or more on a large balance.

Not always before lodging, but definitely before the lender will release construction-line funds. For minor works under $50,000 (kitchen, bathroom, decking, internal walls) that don’t require a DA, you can apply with a builder quote and signed contract. For structural changes—second storey, major extension, garage conversion—you’ll need council development approval or at minimum proof the DA has been lodged. Andy’s advice: lodge the DA early and get conditional loan approval in parallel; once the DA is granted, the lender moves to unconditional and the first draw happens fast.

Typical timeline: 3–5 weeks for approval, then 2–4 weeks to settlement and first draw release. If council approval or builder availability delays the start, the loan can settle and sit dormant (you’re not drawing funds yet, so no extra interest), then the first draw happens when the builder signs the contract and invoices the deposit. For urgent starts, Andy has lenders that do 10-day conditional approvals and 7-day settlement if all documents are ready upfront. The gating item is usually the valuation—Mandurah and Baldivis are fast; rural Pinjarra can stretch to 10 days.

Three options: scale back the scope, increase your deposit, or accept a higher LVR and pay LMI. Andy runs the numbers for each. Often the difference between an 80% LVR (no LMI) and 85% LVR (with LMI) is $5,000–$8,000 in premium, but that might be worth it if the renovation adds $100k+ in value and you plan to stay long term. Alternatively, split the project into two stages: fund stage one now within your 80% limit, then refinance again in 12–18 months once the property has revalued higher—many coastal-suburb families do alfresco and pool first, then second-storey bedrooms a couple of years later.

Yes, if the lender allows ‘owner-builder’ or ‘supply and install’ splits. Some construction-line lenders require a licensed builder contract for the full scope; others let you split the loan—one portion to the builder for labour, one released to you for materials, appliances, and fixtures. This is common for kitchens (you buy the joinery and appliances, the builder installs) or landscaping. You’ll need itemised quotes showing the split, and the lender will still want invoices at each progress claim. Andy’s panel includes lenders flexible on this; just be clear upfront whether you’re contracting the whole job or managing part of the supply chain.

It depends on the structure. With a construction line / progress payments, you pay interest only on money advanced to date—a first draw of $30k means interest on $30k, then a second draw lifts it to $70k. With an equity release / single advance, the full amount is in your loan from settlement and interest is charged on the full balance immediately. If you park it in an offset and draw it down as the builder invoices, the offset cancels interest on unspent funds; without an offset, you pay on the lot. This is why staged-draw products save money on long builds—over 10 months the gap can be $3,000–$6,000.

Budget overrun: if the builder hits you with variation costs, you can apply for a top-up if you have equity headroom—Andy can lodge a variation to the construction line or arrange a small redraw to cover a minor gap ($5k–$10k). Timeline blowout: construction lines typically have a 12–18 month draw window; if the builder is still working at month 14, the lender may extend the window or convert the facility to standard variable early. Either way you keep the loan—there’s no penalty for the builder taking longer, just potentially interest on partially drawn funds for longer than planned.

Absolutely. Refinancing an investment property to fund renovations works the same way—equity release or construction line, depending on scope. The key tax advantage: interest on the renovation portion is deductible as a cost of earning rental income, just like the interest on the original purchase loan. Keep the renovation funds in a separate loan split so your accountant can clearly identify the investment interest, and keep all builder invoices and council approvals. Depreciation also applies to new kitchens, bathrooms, flooring, and fixtures. Always confirm treatment with your accountant, but Andy sets the loan up to make the split transparent.

Most borrowers stay variable during construction because you’re making interest-only repayments on a rising balance as each draw is released, and variable gives flexibility to make extra repayments or offset the loan if the project finishes early with cash left over. Once the renovation is complete and the balance is stable, you can fix part or all of it—many lenders let you split, say 50% variable / 50% fixed for 2 years. Fixed loans during construction can be tricky because repayments jump with each draw and extra repayments are often capped. Andy’s general rule: stay variable during the build, then consider fixing 6–12 months after completion if rates are favourable.

A renovation loan is secured against your existing home’s value—you’re borrowing extra on top of your current mortgage to fund alterations or additions. A construction loan for a new build (land + build, or knockdown-rebuild) assesses the land value and the ‘as-if-complete’ value of the finished house, often with more conservative LVRs (70–80%) and stricter progress inspections. Both use staged draws, but new builds typically have 5–6 milestones (slab, frame, lock-up, fixing, practical completion) vs 3–4 for renovations. Andy handles both, but renovations are simpler because the dwelling already exists, so there’s less lender risk and faster approvals*.

You can live there during most renovations—and most families do to save on rent. Lenders don’t require you to move out unless the work makes the home uninhabitable (full gut renovation, asbestos removal, major structural work that red-tags the dwelling). For typical projects—new kitchen, bathroom, second-storey addition, alfresco—you stay put and the lender’s progress inspections happen while you’re living there. The only loan implication is if the property becomes temporarily unliveable and you move into a rental; some lenders then adjust the serviceability test slightly to account for the rent paid elsewhere. In practice this rarely changes the approval—Andy just flags it upfront if your builder warns you’ll need to move out for 2–3 months.
