Construction Loans

A construction loan is a specialised type of financing designed to fund the building of a new home or a major renovation. Unlike a standard home loan, funds are not released as a lump sum. Instead, they are drawn down in stages as each phase of the build is completed. This staged approach means you pay interest only on the money actually drawn, which can help manage cash flow throughout the project. Once construction is finished, the loan typically converts to a standard home loan with principal and interest repayments.

Natloans works with a panel of over 50 banks and non-bank lenders and provides broker guidance across the full construction loan process, from initial planning through to drawdown and loan conversion. The rate referenced in the page title — from 5.25% p.a. — was published on the Natloans website (page last modified 5 October 2026); rates are subject to change and must be confirmed directly with Natloans before relying on them.

How a Construction Loan Works

Construction loans operate differently from standard home loans in two important ways: how funds are released and how interest is calculated during the build.

Progress Payments

Funds are released in stages — commonly called progress payments — as the builder reaches agreed milestones. The page published by Natloans identifies five typical construction phases:

  1. Foundation — site preparation and slab or footings
  2. Frame — wall and roof framing
  3. Lockup — external walls, windows and doors installed
  4. Fit-out — internal fixtures, fittings and services
  5. Completion — final inspection and handover

At each stage, the builder submits a progress invoice. The lender verifies the milestone before releasing the next payment.

Interest During Construction

During the construction period, interest is charged only on the amount drawn down at any point in time, not on the full approved loan amount. This can reduce the cost of the loan while the build is underway.

Loan Conversion

Once construction is complete, the loan typically converts to a standard home loan and regular principal and interest repayments begin. The specific conversion terms depend on the lender and loan product selected; confirm the details with Natloans for your project.

Step-by-Step Guide to a Construction Loan

Natloans describes the following process for a standard construction loan application and drawdown.

1. Plan Your Project

Prepare detailed building plans and a cost estimate from a licensed builder. Ensure all permits and development approvals are in place before approaching lenders.

2. Speak to a Natloans Specialist

Book a free consultation. A Natloans broker will assess your needs, compare suitable lenders from the panel, and guide you through the application process.

3. Pre-Approval

Submit your financial documents and project details to obtain pre-approval. Pre-approval does not constitute final approval; it provides an indication of the amount a lender may be willing to lend, subject to full assessment.

4. Final Approval and Valuation

Provide the builder's fixed-price contract, project timeline and costs. The lender arranges a valuation to confirm the property's projected end value.

5. Drawdown Process

Funds are released progressively as each building milestone is completed. Progress invoices are submitted to the lender for verification before each payment is released.

6. Completion and Loan Conversion

Once construction is complete, the loan converts to a standard home loan and regular repayments commence.

Documents Typically Required

The Natloans construction loans page identifies the following documents as part of the application. Lender-specific requirements may vary; confirm with Natloans for your project.

  • Detailed building plans
  • Fixed-price building contract from a licensed builder
  • Proof of income
  • Permits and development approvals
  • Detailed cost estimate and project timeline

Construction Loans for Multi-Unit Developments

Natloans also provides guidance on financing multi-unit residential developments, such as 2–4 units or townhouses. These loans operate similarly to standard construction loans — with progressive payments tied to building milestones — but are specifically designed for projects involving multiple dwellings and may carry stricter requirements and higher loan limits.

Why Consider a Multi-Unit Development?

Capital growth and rental income outcomes depend on market conditions and individual project factors. These are general considerations, not guaranteed results.

How Natloans Supports Multi-Unit Development Finance

Frequently Asked Questions

How is construction funding released?

Natloans describes staged progress payments tied to building milestones rather than releasing the entire construction amount at once. Typical phases are foundation, frame, lockup, fit-out and completion. At each stage, the builder submits a progress invoice and the lender verifies completion before releasing the next payment. Source: natloans.com.au/home-loans/construction-loans

What documents does Natloans identify for a construction loan application?

The page lists building plans, a fixed-price building contract, proof of income, and permits or approvals. A detailed cost estimate is also recommended. Lender-specific requirements may differ; confirm the full list with Natloans for your project. Source: natloans.com.au/home-loans/construction-loans

How are repayments structured during and after construction?

During construction, interest is charged only on the funds drawn down at each stage, not the full loan amount. Once construction is complete, the loan typically converts to a standard home loan with principal and interest repayments. The specific structure depends on the lender and loan product; confirm the terms in your loan documentation. Source: natloans.com.au/home-loans/construction-loans

What happens if construction costs exceed the budget?

The Natloans page notes that extra costs beyond the approved loan amount would generally need to be funded by the borrower. It recommends careful budgeting and including a contingency fund from the outset. Discuss the project budget and any potential variations with your builder and Natloans before finalising the loan amount. Source: natloans.com.au/home-loans/construction-loans

How much deposit do I need for a construction loan?

Most lenders require a 20% deposit. Some lenders may accept a lower deposit with Lenders Mortgage Insurance (LMI). The applicable requirement depends on the lender and your financial position; confirm with Natloans.

Can a construction loan be used for renovations?

Yes, according to the Natloans page, construction loans can fund renovations if they meet certain criteria — for example, if the work is structural or involves significant changes. Whether a specific renovation project qualifies depends on the lender's assessment; discuss your plans with Natloans.

Do I need a fixed-price building contract?

Most lenders require a fixed-price building contract to manage risk. The Natloans page notes that borrowers with strong serviceability and equity in other property may in some cases be able to secure finance without a formal construction loan structure, but this is not the standard position. Confirm the requirement for your project with Natloans.

Are multi-unit development loans different from standard construction loans?

Yes. While they share the progressive payment structure, multi-unit development loans are designed specifically for projects involving multiple dwellings (such as 2–4 units or townhouses) and may have stricter lending requirements and higher loan limits than standard construction loans.

How much deposit is needed for a multi-unit development loan?

Typically 20–30% of the total project cost, though this varies by lender. Confirm the specific requirement for your development with Natloans.

What happens if the construction timeline extends?

The Natloans page recommends working with a lender that offers flexible terms to accommodate timeline variations. Natloans can assist in identifying lenders with appropriate flexibility for your project.

Can I subdivide and sell multi-unit dwellings individually?

Yes, but council approval and separate titles for each unit are required. Engaging a town planner or architect early in the process is recommended to ensure compliance with local zoning laws and building codes.

What rate is available for construction loans?

The Natloans page references rates from 5.25% p.a. (as published, last modified 5 October 2026). Rates are not independently verified as current and will vary based on the lender, loan type and your financial circumstances. Confirm the current available rate with Natloans before making any decisions.
