Your construction project can stall before a single brick is laid if your finance structure doesn't account for council delays, cost variations, or builder insolvency.
Construction finance works differently from standard home loans. Rather than receiving the full loan amount upfront, funds release in stages as your build progresses. This protects lenders but creates exposure points for borrowers that many don't anticipate until problems emerge. In St Kilda, where heritage overlays and stricter planning controls affect many properties, these risks intensify.
Fixed Price Contracts Don't Always Mean Fixed Costs
A fixed price building contract provides cost certainty for the agreed scope of work, but variations sit outside that protection. Changes you request during construction, unforeseen site conditions, or upgrades to materials all trigger additional costs that fall outside your contract.
Consider a buyer building a two-storey townhouse on a subdivided block near Acland Street. Their fixed price contract covered $580,000 in building costs, but asbestos discovered during excavation added $22,000 in remediation fees. The builder also identified poor soil conditions requiring deeper footings, adding another $15,000. Neither cost appeared in the original contract, and the buyer's construction loan only covered the agreed amount plus a 10% contingency buffer of $58,000. They needed to source an additional $37,000 mid-project or halt construction.
Your lender assesses your loan amount based on submitted plans and the contracted build cost. When variations push total costs higher, you either fund the difference from personal savings, negotiate additional borrowing capacity if your servicing allows, or reduce scope elsewhere in the project. That last option becomes difficult once construction has commenced.
Progress Payment Timing Can Create Cash Flow Pressure
Lenders release funds according to a progressive drawdown schedule, typically aligned with five or six construction stages. Your builder invoices for work completed, you submit a claim to your lender, they arrange an inspection, and then release funds. This process takes between seven and fourteen days in most cases.
The timing gap creates cash flow pressure. Builders often require payment within seven days of invoicing, but your lender may take two weeks to inspect and release funds. Some builders demand deposits before commencing each stage, which means you're funding portions of the build before your lender reimburses you.
In St Kilda, where many builds involve renovating your house or constructing on smaller inner-city blocks, trades often work across multiple projects simultaneously. Delayed payments can push your electricians or plumbers to prioritize other jobs, extending your build timeline. Every week of delay adds holding costs if you're paying rent elsewhere or interest on drawn funds.
Some lenders charge a progressive drawing fee each time they release funds, typically between $300 and $500 per draw. Across six progress payments, that adds $1,800 to $3,000 to your total project cost. Other lenders include unlimited draws within their construction loan structure. These differences matter when your build extends beyond the standard stages due to custom design or council-required modifications.

Council Approval Delays Affect More Than Your Timeline
Most construction loan approvals require you to commence building within a set period from the disclosure date, typically six or twelve months. If council approval delays push you beyond that window, your approved interest rate may no longer apply, or your loan approval may lapse entirely.
St Kilda sits within the City of Port Phillip, where planning applications for properties near the foreshore, within heritage overlays, or affecting streetscape character often require extended assessment periods. A development application that takes eight months to approve leaves minimal time to finalise your building contract and commence construction before your finance approval expires.
Rates can shift significantly during extended approval periods. If your construction loan application locked in a rate that later increases, your borrowing capacity may decrease when you return to draw funds. The opposite scenario helps you, but lenders don't reduce their assessment rate when market rates drop, they apply the higher of the two.
Your registered builder also operates within these constraints. Many quality builders won't hold pricing beyond 90 days due to material cost volatility. If your council approval takes longer, you may need to renegotiate your building contract at higher rates, which then requires reassessing your loan amount and servicing capacity.
Interest Compounds While You're Not Yet Living There
Construction loans only charge interest on the amount drawn down, not your total approved limit. During the build, most borrowers select interest-only repayment options to minimize costs while they're still paying rent or covering their existing mortgage elsewhere.
However, interest still accrues on every dollar your lender releases. On a $650,000 construction loan, if $400,000 has been drawn over the first four months of your build, you're paying interest on that $400,000. At current variable rates, that represents roughly $1,650 per month in interest charges. If your build extends from the projected six months to nine months due to weather delays, material shortages, or trade availability, you're carrying those interest costs for an additional three months while also covering your current accommodation expenses.
Many buyers underestimate total holding costs during construction. Beyond loan interest, you're often covering council rates on the land, building insurance from practical completion, and storage costs for furniture if you've vacated a previous property. These expenses compound when builds run over schedule, which happens more often than projected timelines suggest.
Once construction reaches practical completion, your loan typically converts to a standard principal and interest mortgage through a construction to permanent loan structure. Some lenders automatically convert your facility, while others require you to reapply and meet servicing criteria at that point. Knowing which structure your lender uses matters, particularly if your financial circumstances change during the build period.
Builder Insolvency Leaves You With Incomplete Work and Ongoing Debt
Your lender releases funds based on work completed to date. If your builder becomes insolvent halfway through construction, you've already paid for materials and labor through the progressive payment schedule, but you're left with an incomplete build and a loan balance that reflects the work done.
Sourcing a new builder to complete someone else's work typically costs more than the original contract price for that remaining scope. New builders need to assess existing work quality, take on liability for structural elements they didn't install, and price risk into their quote. They're also less motivated to offer competitive rates on completion work compared to full projects.
Access to construction loan options from multiple lenders becomes crucial when builder insolvency occurs. Some lenders allow you to hold your current loan while seeking additional finance to complete the build. Others require you to refinance the entire amount, which depends on your property's current valuation in its incomplete state and your ongoing servicing capacity.
Protection exists through builder warranty insurance in Victoria, but coverage has limitations and excess payments. The insurance covers incomplete work up to a capped amount, but doesn't reimburse you for delays, holding costs, or the difference between your original contract and the completion cost.
Protecting Your Position Before You Commit
Your loan structure should account for realistic worst-case scenarios, not just projected timelines and costs. Building a contingency buffer into your loan amount helps, but only if your income supports the higher borrowing level and the buffer is sufficient for likely variations.
Working with a mortgage broker in St Kilda who understands local planning requirements means your finance timeline aligns with realistic council approval periods. Someone familiar with the area knows which property types face extended assessment, which lenders offer longer rate locks, and how to structure your application to maintain flexibility if delays occur.

Frequently Asked Questions
What happens if my construction costs exceed the loan amount approved?
You need to fund the difference from personal savings, apply for additional borrowing if your income supports it, or reduce the project scope. Lenders base your loan amount on the contracted build cost and submitted plans, so variations and unforeseen site conditions fall outside the approved amount.
How long does it take for construction loan funds to release after invoicing?
Most lenders take between seven and fourteen days to inspect completed work and release funds. Your builder typically requires payment within seven days of invoicing, which can create cash flow pressure during the build period.
Do I pay interest on the full construction loan amount during the build?
No, lenders only charge interest on the amount drawn down at each stage. However, interest compounds on every dollar released while you're still paying rent or covering other accommodation costs, which increases total holding costs if the build extends beyond the projected timeline.
What happens to my loan approval if council approval takes longer than expected?
If council delays push you beyond your lender's commencement period (typically six to twelve months), your approved interest rate may no longer apply or your loan approval may lapse entirely. You would need to reapply at current rates, which could affect your borrowing capacity.
What protection exists if my builder becomes insolvent during construction?
Builder warranty insurance in Victoria covers incomplete work up to a capped amount, but doesn't cover delays, holding costs, or the higher costs typically involved in getting a new builder to complete another builder's work. Some lenders allow additional finance for completion, while others require full refinancing.
