Construction loan monitoring is the mechanism lenders use to verify building stages are complete before releasing funds from your loan amount. The lender appoints a certifier who physically attends the site, confirms the work matches the progress payment schedule, and authorises the next drawdown.
This process protects both you and the lender, but it introduces variables that affect cashflow, settlement costs, and final project budgets in ways that differ from standard home loans for lawyers. You only pay interest on the amount drawn down at each stage, not the full loan amount, but the timing of those drawdowns determines when your repayments increase and when your builder receives payment. The gap between completion, inspection, and fund release is where most lawyers encounter unexpected delays or cost overruns.
How Construction Draw Schedules Work
The draw schedule is agreed between you, the builder, and the lender before construction starts. Most fixed price building contracts follow a five-stage model: deposit or base stage, frame stage, lock-up, fixing, and completion. Each stage represents a percentage of the total contract price, typically around 10%, 15%, 35%, 25%, and 15% respectively, though variations exist.
Your builder submits a payment claim when they reach a stage. The lender's certifier then inspects the site within a few business days, usually three to five. If the work is verified, the lender releases funds to the builder. You start paying interest on that drawn amount from the date it is released. The timing matters because if a stage is delayed by weather, supply issues, or council inspections, your builder is not paid until that stage is formally certified.
Consider a lawyer building a custom design on suitable land in a regional area. The frame stage was delayed by two weeks due to rain, but the builder had already ordered materials and engaged sub-contractors. The builder absorbed the delay cost, but the next stage was held up because the certifier identified incomplete weatherproofing. The lender withheld $80,000 until rectification was complete, which took another week. The builder's cashflow tightened, and the lawyer had to manage the risk that the builder might prioritise other projects to maintain their own liquidity.
Progress Inspection Timing and Payment Gaps
The inspection does not happen immediately after the builder claims a stage is complete. Most lenders allow three to five business days for the certifier to attend, and that window can stretch if the certifier is managing multiple sites or if access is difficult. Once the inspection is complete, the lender processes the drawdown, which usually takes another one to two business days.
This creates a gap of up to a week between the builder finishing a stage and receiving payment. If your building contract specifies payment within five business days of a claim, and the lender takes seven days to inspect and release funds, the builder may stop work or invoke a delay clause. This is more common with smaller or regional builders who operate on tight cashflow margins.
In a scenario where a lawyer is building a project home under a fixed price contract, the builder claimed the lock-up stage on a Friday. The certifier attended the following Wednesday due to scheduling conflicts, identified minor defects in the window installation, and required rectification before approval. The builder corrected the work by Friday, but the certifier did not return until the following Tuesday. The lender released funds on Thursday, 12 business days after the original claim. The builder issued a formal delay notice, which did not affect the contract price but created friction and slowed momentum on the fixing stage.

What the Progressive Drawing Fee Covers
Lenders charge a progressive drawing fee, sometimes called a progress payment fee, for each inspection and drawdown. This fee typically ranges from $300 to $500 per stage, though some lenders cap it at a total amount across the entire build. The fee covers the certifier's attendance, report preparation, and the lender's administrative cost of releasing funds in instalments rather than a lump sum.
This is separate from the construction loan interest rate and is usually paid upfront or debited from your loan account at each stage. Over a five-stage build, you might pay $1,500 to $2,500 in progressive drawing fees. Some lenders bundle this into a single fee at settlement, while others charge per draw. Clarify this during your construction loan application because it affects your upfront cash requirement.
Interest Only Repayment Options During Construction
Most construction to permanent loan structures offer interest-only repayment options during the building phase. You pay interest monthly on the cumulative amount drawn down, not the full loan amount. Once construction is complete and the final drawdown occurs, the loan converts to principal and interest repayments unless you have arranged otherwise.
This structure reduces your repayment burden while the build is underway, which is useful if you are also paying rent or managing an existing mortgage. However, your repayments increase each time a new stage is drawn. If the frame stage draws $100,000 and your interest rate is 6.5%, your monthly interest cost increases by roughly $540. By lock-up, you might be paying interest on $250,000, which is $1,350 per month. If your build timeline extends due to delays, you pay interest for longer than anticipated.
Cost Plus Contracts and Monitoring Complexity
A cost plus contract differs from a fixed price building contract because the final price is not set at the outset. The builder charges their actual costs plus a margin, typically 10% to 15%. This structure is more common for custom designs or renovations where scope is difficult to define precisely.
Lenders are more cautious with cost plus contracts because the loan amount is not fixed. They usually require a detailed cost breakdown and may limit the loan to a percentage of the estimated total, typically 80% to 85%, rather than the 90% to 95% available under fixed price contracts. Progress inspections become more detailed because the certifier must verify not only that work is complete but that costs align with the estimates.
This adds time and complexity to each drawdown. If you are building under a cost plus arrangement, expect longer gaps between payment claims and fund release, and ensure you have sufficient cash reserves to cover cost overruns or scope changes that exceed the approved loan amount.
When the Builder or Owner Builder Engages Sub-Contractors Directly
If you are acting as an owner builder, the lender releases funds directly to you, not to a registered builder. You are then responsible for paying sub-contractors, including plumbers, electricians, and framers, as each stage completes. The certifier still inspects and verifies progress, but you manage the payment schedule and cashflow.
This introduces additional risk because if you miscalculate costs or if a sub-contractor disputes payment, the lender will not release the next drawdown until the dispute is resolved. Most lenders require owner builders to provide statutory declarations confirming all sub-contractors have been paid before approving subsequent stages. Some lenders do not offer owner builder finance at all, and those that do typically require higher deposits and charge higher interest rates to offset the increased risk.
Council Approval and Development Application Timing
The lender will not release the first drawdown until you have council approval and the building contract is signed. If your development application is delayed or requires resubmission, this pushes back your entire construction timeline. Most lenders also require you to commence building within a set period from the Disclosure Date, usually six months, or the loan approval lapses.
If you are purchasing a land and construction package or house & land package, the developer usually manages council plans and approvals, which accelerates the process. If you are building on land you already own or designing a custom home, you are responsible for the development application. Delays here are common, particularly in areas with heritage overlays or bushfire zones, and they directly affect when construction funding becomes available.
How Delays Affect Your Interest Cost and Completion Date
Every week of delay extends the period you pay interest on the drawn amount without moving closer to completion. If your build was scheduled for six months but takes nine months due to weather, supply chain issues, or builder delays, you pay an additional three months of interest on each drawn stage.
Lenders do not usually extend the construction loan term automatically. If your build exceeds the agreed period, you may need to request an extension, which can involve additional fees or reassessment of your financial position. If your circumstances have changed, such as a reduction in income or an increase in other debts, the lender might decline the extension or require additional security.
What Happens if the Builder Stops Work or Goes Insolvent
If your builder ceases work before completion, the lender freezes further drawdowns until you either engage a new builder or demonstrate the project can be completed. The lender's certifier will assess the work completed to date and determine the portion of the loan that has been properly drawn. If funds were released for work that was not completed, you are liable for the shortfall.
Most lenders require builders to hold contract works insurance, which covers incomplete work if the builder becomes insolvent. However, this insurance does not cover poor workmanship or disputes over scope. If you are mid-build and the builder exits, expect delays of several months while you engage a replacement and renegotiate contracts. During this time, you continue paying interest on the amount already drawn.

Frequently Asked Questions
How long does a progress inspection take during construction?
The certifier typically attends within three to five business days of the builder's payment claim. After inspection, the lender processes the drawdown in another one to two business days, creating a total gap of up to a week between stage completion and fund release.
What is a progressive drawing fee and how much does it cost?
A progressive drawing fee is charged by the lender for each stage inspection and drawdown, typically $300 to $500 per stage. Over a standard five-stage build, total fees range from $1,500 to $2,500, paid either upfront or debited from the loan at each stage.
Do I pay interest on the full construction loan amount during the build?
No, you only pay interest on the amount drawn down at each completed stage, not the full loan amount. Repayments increase progressively as each stage is certified and funds are released.
What happens if my builder stops work before the project is finished?
The lender freezes further drawdowns until you engage a new builder or prove the project can be completed. The certifier assesses work done to date, and you remain liable for any shortfall if funds were released for incomplete work.
Can I act as an owner builder with a construction loan?
Some lenders permit owner builder finance, but they typically require higher deposits, charge higher interest rates, and release funds directly to you rather than a registered builder. You must provide statutory declarations confirming sub-contractors are paid before each subsequent drawdown.
