Knock Down Rebuild Loans Australia

Quick Answer

What is a knock down rebuild loan in Australia?

A construction loan that funds demolition and rebuild on the same block

A knock down rebuild loan combines demolition costs with a standard construction loan, drawn in staged progress payments against the projected end value of the completed home. Lenders assess the loan based on the finished property valuation, council approvals and a fixed-price building contract with a licensed builder.

  • Typical bank LVR Up to 80% of end value
  • With LMI Up to 90% of end value
  • Progress payments 5 to 6 staged draws
  • Key lender focus End value, DA, fixed contract

A knock down rebuild loan is used when you own a block with an existing home that you want to demolish and replace with a new build. The demolition costs are included in the total loan amount, which is then drawn down in stages as construction progresses.

The lender assessment is based on the completed home's projected value, not the current land value. A council development approval, demolition permit and a fixed-price contract with a licensed builder are typically required before the loan can be fully approved.

This page covers the specific lending criteria for KDR loans. For the broader category, see construction loans.

Two factors that shape your knock down rebuild loan

icon

End value and project cost

Lenders assess KDR loans against the projected end value of the completed home, not the current land value. The total loan must cover the demolition costs, build contract and any existing mortgage payout. A conservative end-value estimate from the lender's valuer can affect how much you can borrow.

Approvals and builder requirements

Most lenders require a council DA and demolition permit before a KDR loan can settle. A signed fixed-price building contract from a licensed, registered builder is also usually required. Missing either of these at application stage can delay or stall the loan.

Approval Risk
Typical LVR ranges for knock down rebuild loans

These are general guide ranges only. Final terms depend on the end-value assessment, borrower profile, location and lender appetite.

  • Up to 65% LVR Complex site or regional location
  • Up to 75% LVR Standard KDR, suburban location
  • Up to 80% LVR Metro KDR, licensed builder, fixed contract
  • Up to 90% LVR With LMI, strong borrower, standard build

KDR loans are assessed on the end value of the finished home, not the current value of the land. The lender needs confidence the completed property will support the debt before draw-downs begin.

Thinking about knocking down and rebuilding?

What lenders look for in a knock down rebuild loan

KDR loans are assessed on the completed home's projected value, the strength of the approvals and contracts in place, and the borrower's ability to service the debt during and after the build.

  • icon Signed fixed-price contract with a licensed builder
  • icon Council development approval and demolition permit
  • icon End-value assessment supporting the total loan amount
  • icon Adequate deposit or equity in the existing land
  • icon Clear plan to manage or payout any existing mortgage

If your build is larger in scope, you may also want to explore property development finance.

Common knock down rebuild scenarios financed

Most lenders will consider a KDR where the end value, approval status and build contract are clearly documented.

  • icon Owner-occupier KDR
  • icon Investment KDR
  • icon KDR on inherited land
  • icon Knock down and duplex
  • icon KDR with bridging finance

If you need to fund a temporary move during demolition, ask about renovation loan options or bridging structures.

Key factors for knock down rebuild finance

These factors usually determine whether a KDR loan fits a standard bank pathway or needs a specialist construction lender.

01

End value assessment

The lender's valuer estimates the completed home's value before the loan is approved. A conservative end-value figure can reduce the available loan amount.

02

Fixed-price building contract

Lenders require a signed fixed-price contract with a licensed builder before the loan can be fully assessed. Cost-plus or informal arrangements are generally not accepted.

03

Demolition costs

The cost of demolition must be factored into the total loan amount. Asbestos removal, excavation and site clearance costs can add significantly to the project budget.

04

Progress payment schedule

The loan is drawn in stages tied to construction milestones such as slab, frame, lock-up, fit-out and completion. Interest is only charged on the drawn portion during the build.

05

Council approvals

Most lenders require a development approval and demolition permit before settlement. DA delays are one of the most common reasons KDR loan timelines stretch out.

06

Existing mortgage payout

If you have an existing home loan on the property, it must generally be refinanced into the new KDR construction loan. This affects how much additional borrowing capacity you have.

Common problems with knock down rebuild finance

KDR projects have more moving parts than a standard purchase. Here are the issues that most commonly hold up or reduce a KDR loan.

icon

End value comes in lower than expected

If the lender's valuer estimates a finished value below your projections, the available loan amount may be reduced, which can affect your budget or deposit requirements.

Get a realistic independent estimate of the end value before committing to the build contract.
icon

DA delays push back settlement

Council approval timelines can vary significantly by location and project. Delays in receiving a DA or demolition permit can push back finance settlement and builder start dates.

Submit your DA application early and allow buffer time in your finance pre-approval conditions.
icon

Existing mortgage not factored into borrowing capacity

Many borrowers overlook that the payout of an existing home loan must be included in the total KDR loan. This reduces the amount available for demolition and construction costs.

Calculate your total project cost including the existing loan payout before approaching a lender.
icon

Builder not accepted by the lender

Lenders require a licensed and registered builder. Engaging a builder before confirming they meet the lender's requirements can create problems later in the application process.

Confirm builder licensing and lender acceptance before signing the building contract.

How to get a knock down rebuild loan in 6 steps

Step

01

Confirm land ownership and demolition eligibility

Check the title, any existing mortgage, covenants and whether demolition is permitted under local planning rules.

Step

02

Engage a builder and get DA plans prepared

Work with a licensed builder or architect to prepare plans suitable for a council development approval application.

Get a signed, fixed-price contract from your licensed builder covering the full scope of work including demolition.

Step

05

Apply for the KDR construction loan

Submit the full application including financials, DA, building contract and plans. The lender will order an end-value assessment of the completed home.

Step

06

Draw down in progress payments

Once the loan settles, funds are released in staged progress payments as construction milestones are completed and certified.

How knock down rebuild finance works in Australia

A knock down rebuild loan is a type of construction loan used when you already own a block and want to demolish the existing structure and build a new home. It is distinct from a standard construction loan because the demolition costs are included in the total project amount, and the lender needs to understand both the current land position and the projected end value of the finished build.

Unlike buying land and building new, a KDR project starts with an existing asset that may already have a mortgage attached to it. If there is an existing home loan on the property, the new KDR construction loan must pay it out and roll the balance into the new facility. This affects your total borrowing capacity and the deposit calculation.

The loan is drawn in progress payments tied to construction milestones, which typically include base or slab, frame, lock-up, fit-out and practical completion. During the build, interest is generally only charged on the drawn balance rather than the full loan limit. Once construction is complete, the loan converts to a standard principal and interest home loan.

The right lender for a KDR depends on the borrower profile, the complexity of the build and whether the site presents any unusual demolition or approval challenges. A borrower with strong income, a straightforward block and a licensed builder in a metro area may suit a mainstream bank. Projects with unusual demolition requirements, asbestos, non-standard builds or a self-employed borrower may need a specialist construction lender.
