What is Commercial Development Finance & How Does It Work?

Commercial development finance provides funding for projects that add commercial or mixed-use structures to land you own or intend to acquire.

This type of loan differs from standard commercial property finance because it releases funds progressively as construction milestones are reached, not as a lump sum at settlement. Lenders assess your project's feasibility, exit strategy and your capacity to service the loan during construction, often when rental income has not yet commenced.

The funding structure reflects the risk profile. Most lenders advance 60% to 70% of total project cost, with some stretching to 75% where presales, tenant commitments or your own equity position are particularly strong. You cover the balance through cash equity, mezzanine finance, or joint venture arrangements.

How Lenders Assess a Commercial Development Application

Lenders start with your project's end value and work backward.

They commission an independent valuer to estimate the completed asset's market value, either as a single strata title or multiple tenancies. That valuation informs the loan-to-value ratio. If the valuer assesses the finished project at $3 million and total build cost sits at $2.4 million, a lender advancing 65% of cost would release $1.56 million. You fund the $840,000 shortfall, plus any land acquisition cost not covered within the facility.

Your exit strategy carries as much weight as the build budget. Lenders want to see either a contracted presale, signed lease commitments that support a refinance into investment-grade commercial property finance, or a clear takeout buyer. In our experience, applicants who present tenant letters of intent from established businesses materially improve their approval odds and often negotiate lower margins.

Serviceability during construction is assessed separately from the end state. Most commercial construction facilities are interest-capitalised, meaning the lender rolls accrued interest into the loan balance each month rather than requiring cash payments. Your serviceability is then tested against the capitalised balance at practical completion, using either actual lease income or a valuer's assessment of market rent.

Progressive Drawdown and How Funds Are Released

Funds are not available on day one.

The lender appoints a quantity surveyor who inspects the site at each stage and certifies that the claimed work has been completed to the required standard. You submit a progress claim, the surveyor verifies it, and the lender releases the next tranche. Drawdowns typically align with slab down, frame up, lockup, fix-out and practical completion, though the exact schedule depends on your contract and the lender's policy.

Most facilities hold back 5% to 10% of each drawdown as a retention buffer, released only once defects are remedied and all subcontractor invoices are cleared. If your builder is also seeking staged payments under a construction contract, timing mismatches can occur. Planning your cash flow to cover the gap between when you pay the builder and when the lender reimburses you is part of the preparation.

What Karalee Landholders Should Consider Before Applying

Karalee's zoning and allotment sizes lend themselves to niche commercial uses rather than high-density retail.

Many properties along Mount Crosby Road sit within low-density commercial or mixed-use precincts under Ipswich City Council's planning scheme. A developer seeking to add a small office building, workshop complex, or hybrid retail-and-residence structure on an existing large block would typically engage a town planner early to confirm code-assessable pathways and avoid impact assessment delays.

Council infrastructure charges in Ipswich apply per square metre of gross floor area for non-residential uses and vary by precinct. Charges adopted under the 2023 infrastructure charging resolution remain current, though state referral triggers for stormwater, transport and environmental assessment can extend approval timeframes if your site adjoins the Brisbane River corridor or mapped vegetation.

We regularly see clients underestimate how lender appetite changes depending on tenant quality and lease structure. A 10-year lease to a government department or ASX-listed entity makes your project bankable at 70% loan-to-value. A speculative build with no tenant secured might cap out at 60%, and some lenders will decline outright unless you can demonstrate pre-leasing to at least 50% of the net lettable area.

Interest Rates and Loan Terms on Development Facilities

Commercial development finance is priced as a margin over a benchmark rate.

At current settings, you would expect a variable margin between 2.50% and 4.50% above the 90-day bank bill swap rate, depending on your loan-to-value ratio, project complexity and your experience as a developer. Fixed-rate options are rare on construction facilities because the drawdown profile does not suit a fixed term, though some lenders offer a fixed-rate lock once you reach practical completion and convert to an investment hold.

Loan terms during construction are short. Most facilities run for 12 to 24 months, with the term set to match your build program plus a three-month buffer. If construction runs over time, you can usually negotiate an extension for a fee, typically 0.50% to 1.00% of the outstanding balance, plus an increase in the interest margin.

Once the project is complete and tenanted, you either sell and exit or refinance into a standard commercial investment loan with a longer term and a lower rate. That second facility is assessed on the income the property generates, not the build cost, so ensuring your tenants are in place and paying rent before you apply for the takeout loan avoids costly bridging arrangements.

When Mezzanine Finance or Joint Venture Structures Make Sense

Senior debt from a bank or non-bank lender will only take you so far.

If your project requires $2 million to complete but the senior lender will only advance $1.3 million at 65% loan-to-value, and you have $500,000 in available equity, you face a $200,000 funding gap. Mezzanine finance fills that gap, sitting subordinate to the senior facility and priced accordingly. Expect margins of 8% to 12% plus establishment fees, and in some cases an equity kicker that gives the mezzanine funder a share of sale proceeds or rental upside.

Alternatively, you might bring in a joint venture partner who contributes the shortfall in return for a percentage of the completed asset or profit on sale. This dilutes your ownership but removes the need to service high-cost mezzanine debt during construction. Joint venture agreements should be documented before you lodge the development application to ensure all parties agree on cost overruns, time extensions and exit mechanisms.

Building a Feasibility That Supports Your Application

Your feasibility study is the document lenders read first.

It should include a line-item build budget from a quantity surveyor, not a builder's estimate on a single page. It should model your interest cost month by month, using a realistic drawdown schedule and a margin in line with current pricing. It should include council and state charges, professional fees for the planner, engineer, surveyor and architect, and a contingency of at least 10% for variations and delays.

The revenue side must be supported by comparable lease evidence. If you are assuming $450 per square metre net for an office tenancy in the Karalee precinct, your broker or valuer should be able to point to similar transactions within five kilometres. If no comparables exist, the lender will either discount your revenue assumption or decline the application outright.

Include a sensitivity analysis that shows what happens if construction costs increase by 10%, if leasing takes an extra six months, or if you achieve rent 5% below your base case. Lenders want to see that the project remains solvent under stress, not that it only works if every assumption lands perfectly.

How TAP Mortgage Solutions Structures Development Finance Applications

We work with lenders who understand the difference between a first-time developer and a repeat client.

For clients new to commercial development, we focus on lenders who will consider the strength of the underlying asset and your exit strategy ahead of your development track record. That might mean a lower loan-to-value ratio or a requirement for additional security, but it keeps the application moving rather than facing outright decline from lenders who only write to experienced developers.

We prepare the application with all supporting documents in the format the lender expects: feasibility model, signed builder contract, planning approval or lodged application, valuation instruction, and proof of equity. Missing documents or inconsistencies between your quantity surveyor's budget and your builder's quote are the most common reasons applications stall in credit assessment.

Where your project requires mezzanine or asset finance for equipment used on site, we coordinate those facilities so settlement timing aligns and security ranking is documented before contracts exchange. Call one of our team or book an appointment at a time that works for you, and bring your feasibility, site plans and council pre-lodgement notes if you have them. We will walk through the structure, timeline and lender options that fit your project.
