What Is a First Mortgage Development Loan? How It Works for Property Developers in Australia

A first mortgage development loan is a construction or development facility secured by a first-registered mortgage over the subject property. This gives the lender priority over all other secured creditors in case of default.

This guide explains what the first mortgage position means, how development loans are structured and funded, and what lenders assess when reviewing a development finance application.

Key Takeaways

• A first mortgage gives the lender first-priority security over the development property.
• Development loans are assessed on project feasibility, build costs, borrower capability and exit strategy, not personal income serviceability.
• Funds are released as progressive drawdowns tied to construction milestones, not as a lump sum at settlement.
• First mortgage lenders rank ahead of all other secured creditors, which influences pricing, LVR and loan structure.
• Because Assured Management Limited (AML) lends on GRV, including GST, rather than hard construction costs, developers can often start with a smaller equity contribution than traditional bank finance requires.
• AML has been providing first mortgage construction and development finance across SE QLD and Northern NSW since 1998.

What Is a First Mortgage Loan?

A first mortgage is the primary registered security interest over a property. The lender holds the highest-priority claim against the asset: if the borrower defaults and the property is sold, the first mortgage holder is repaid before any other secured party, including second mortgage holders and unsecured creditors.

This priority position reduces the lender’s exposure, which is reflected in how facilities are priced and structured. For developers, first mortgage debt is generally the most cost-effective component of a development finance structure.

‘First mortgage’ refers to a security position only, not the type of loan or borrower profile. A first mortgage can secure a home loan, a commercial property purchase or a development project.

What Is a First Mortgage Development Loan?

A first mortgage development loan combines a first-priority security position with a facility designed specifically for property development or construction. The lender takes a first-registered mortgage over the development site and funds the project through a series of progressive drawdowns.

These loans are typically used for:

• Land acquisition and construction, where a single facility covers both
• Construction-only facilities where the developer already owns the land
• Residential subdivisions, townhouse projects and multi-unit builds
• Commercial and industrial development
• Service stations and mixed-use projects

The specific structure, including facility size, LVR, drawdown schedule and loan term, varies between lenders and is driven by the project, the borrower’s experience and the strength of the exit strategy.

Assured Management Limited (AML) is a boutique funds manager specialising in first mortgage construction and development finance across SE QLD and Northern NSW. AML operates as a contributory mortgage fund, which means investors are committed for the life of each mortgage. This structure ensures funds are available not just for the initial settlement advance, but for all progress drawdowns throughout the loan term.

How Does a Property Development Loan Work?

Development loans work differently from standard mortgages. Funds are released progressively against construction milestones rather than as a single advance. The typical process looks like this:

1. Enquiry and project summary: The developer provides an overview of the project, including site details, estimated costs and the proposed exit strategy.
2. Indicative terms: If the project fits the lender’s appetite, indicative terms are issued. This lets the developer model the facility into their feasibility before committing to due diligence costs. AML aims to turn approvals around within a few weeks, depending on project complexity and documentation.
3. Due diligence: The lender undertakes a detailed review, including an independent valuation, as-is and on-completion/GRV including GST, a quantity surveyor (QS) report, development approval (DA) documentation and assessment of the borrower and their team.
4. Credit approval and documentation: Formal approval is issued subject to conditions, and loan documents are prepared and executed.
5. Settlement: The first mortgage is registered, and the initial advance is made.
6. Construction drawdowns: As the build progresses, the developer submits drawdown requests. The lender or appointed inspector verifies progress against the QS schedule before releasing funds for each stage.
7. Exit: The facility is repaid through lot sales, refinances, or staged mortgage releases as dwellings or lots are sold.

First Mortgage vs Second Mortgage in Development Finance

The distinction is about security ranking. The first mortgage lender holds a senior, priority claim. The second mortgage lender holds a subordinate claim that is only satisfied after the first mortgage debt is repaid.

For developers, this matters because first mortgage debt is generally lower cost than second mortgage or mezzanine debt. Second mortgage facilities are typically used to top up a capital structure where the senior lender does not cover the full funding requirement. Many projects are funded by first mortgage debt alone.

What Lenders Look For in First Mortgage Development Finance

Security and Valuation

An independent valuation of the site is required, covering both the as-is value and the on-completion Gross Realisable Value (GRV, including GST). AML lends to 65% LVR on both the as-is valuation and GRV, including GST, and aims to hold the cost to complete within the facility at all times.

Feasibility and Contingency

Lenders need to see that the project is commercially viable at the proposed loan level. Revenues need to be achievable, costs realistic and an adequate contingency built in. Projects with thin margins or optimistic cost estimates receive more scrutiny.

Project Timeline and Build Costs

The construction programme is reviewed against the facility term and QS cost report. A well-evidenced build programme, including milestones and builder credentials, gives lenders confidence that the project can be delivered within the loan term.

Borrower Capability and Team

Lenders assess the borrower’s development experience, financial capacity and the broader team, including the builder, project manager and sales agent. First-time developers may need to demonstrate their capability through their advisors or by partnering with more experienced operators.

Exit Strategy

This is the most important factor in any development loan assessment. Lenders need a clear understanding of how the debt will be repaid, whether through presales, lot releases, refinance or a combination. A credible exit strategy that stacks up against current market conditions and comparable sales evidence significantly de-risks the loan.

How Much Deposit Do I Need for Development Finance?

Because AML is based on Gross Realisable Value (GRV, including GST) rather than the traditional hard-cost method, there is no limit on Total Development Cost (TDC) and in some circumstances, AML can fund up to 100% of project costs. This means developers can often secure funding with significantly smaller equity contributions than would be required under traditional bank finance, and can get started on projects sooner.

In cases where the 65% LVR leaves a developer a little short, a facility can be structured to incorporate the developer’s GST refunds into the loan facility to assist in funding the cost to complete.

While the upfront costs of non-bank finance may appear higher at face value, the overall equity outlay required from developers is often significantly less compared to traditional bank funding. AML borrowers have consistently completed a greater number of projects within the same timeframe.

How Much Do You Need to Earn for a $700,000 Mortgage?

This question applies to residential home loans, where serviceability is assessed based on income, existing debts, living expenses and the lender’s buffer rate. The answer depends on the specific lender and loan structure.

Development finance is assessed differently. AML and other development lenders do not use personal income serviceability in the same way retail banks do for home loans. The focus is on the project: feasibility, security, build costs, borrower capability and exit strategy. If you are looking for construction finance in SE QLD or Northern NSW, the conversation starts with your project, not your income.

Frequently Asked Questions:

What is a first mortgage loan?

A first mortgage loan is secured by a first-registered mortgage over a property, giving the lender priority over all other secured creditors in the event of a default. In a development context, this security is taken over the development site for the life of the loan.

How does a property development loan work?

Development loans are assessed on project feasibility, security value, build costs, borrower experience and exit strategy. Funds are released as progressive drawdowns at construction milestones, verified by the lender or an appointed inspector, and the loan is repaid through sales, staged releases or refinance at project completion.

How much deposit do I need for development finance?

AML lends to 65% LVR on both the as-is valuation and GRV, including GST, with no limit on Total Development Cost. In some circumstances, AML can fund up to 100% of project costs. A facility can also be structured to incorporate GST refunds where needed. The result is that developers often require significantly less equity than under traditional bank finance.

What is the difference between first mortgage and second mortgage development finance?

A first mortgage lender holds priority security and is repaid before any other secured party on default. A second mortgage lender sits behind the first mortgage and carries greater risk, reflected in higher pricing. Many projects are funded by first mortgage debt alone; second mortgage or mezzanine facilities are used when additional leverage above the senior position is required.

How do progress drawdowns work in construction finance?

As construction reaches key milestones such as slab, frame, lockup and practical completion, the developer submits a drawdown request. The lender or their quantity surveyor verifies progress against the approved QS schedule and releases the corresponding funds. Because AML operates as a contributory fund with investors locked in for the life of each mortgage, funds are available for every drawdown throughout the loan term.

What documents do lenders typically need for a development loan?

Requirements vary, but developers should expect to provide a project feasibility, development approval documentation, a QS cost report or detailed builder’s contract, an independent valuation arranged by the lender, plans and specifications, a statement of assets and liabilities, evidence of the developer’s background and track record, and details of the proposed exit strategy, including any presales.

What types of projects does AML typically fund?

AML provides first mortgage construction and development loans across SE QLD and Northern NSW for townhouses, apartment buildings, land subdivisions, housing estates, industrial complexes and service stations. Loans range from $1,000,000 to $25,000,000 with a maximum term of 18 months.
