Construction loan
A type of home loan structured around the staged payment schedule of a residential build. Funds release in tranches matched to construction stages, with the bank verifying progress at each stage before releasing the next payment.
Definition
A construction loan is a home loan specifically structured for the staged funding of a residential build. Rather than the full loan amount being available from settlement, funds are drawn down in tranches matched to the construction progress payment schedule. The bank verifies that each stage has been reached before releasing the corresponding tranche to the builder.
Why it matters
Most owner-builders and many homeowners building with a contracted builder use a construction loan to fund the build. The construction loan structure is the mechanism that connects the bank's funding to the actual progress of the build, theoretically protecting the bank from disbursing funds against work that hasn't been done. For owners, the construction loan adds a layer of independent verification at each stage but also adds time to each progress payment.
How it works in practice
The owner applies for a construction loan with their lender. The loan is approved up to the contract value (usually with the owner contributing equity from savings or another property). The loan does not fully disburse at settlement. Instead, the funds sit available, and tranches are drawn down as construction progresses.
When the builder completes a stage, they issue a progress claim. The owner forwards the claim to the bank. The bank arranges an independent valuation, typically by an external valuer or quantity surveyor who visits the site and confirms the stage has been reached. The bank releases the tranche to the builder once the valuation is satisfactory.
Each bank inspection adds 1 to 3 weeks to the stage release, depending on the bank, the valuer's availability, and any defect or scope questions raised. Some lenders allow desktop valuations from photographs for smaller stages, which is faster.
During the construction period, the owner usually pays interest only on the amount drawn down (not the full loan facility). Once the build reaches practical completion, the loan converts to a standard principal-and-interest mortgage on the full amount.
Common misconceptions
The bank's inspection guarantees the build is good quality
It doesn't. The bank's valuation confirms the stage has been physically reached for funding purposes, not that the work is up to standard. Owners should still engage their own independent inspector for quality verification.
The bank's process protects the owner from the builder
Partially. The bank's verification adds an independent check on whether stages have been reached, but the funds still go to the builder's general operating account once released, where they can be used for any purpose.
Construction loans are always slower than direct funding
Yes, by 1-3 weeks per stage, sometimes more. This is the trade-off for the bank's verification layer. Owners self-funding the build can release stages faster but assume more verification responsibility themselves.
