Private Lending for Builders With Retention Money Held
When the job is finished and the principal has paid 95 percent, the 5 percent that sits as retention can still be the difference between starting the next build and waiting on a defects period to expire. Here is how private funders read that file.
Quick Answer
A builder retention bridge is read first as an exit question, not a loan question. Private funders rarely take the retention itself as security because release timing sits with the principal. They lend against property equity and use the practical completion timeline as the exit logic.
How a private funder reads a builder's retention bridge
A retention bridge is read first as an exit question, not a loan question. From the private funder lens, the retention balance itself is interesting but not load-bearing. What sits in the file is a builder who has finished a job, been paid most of the contract, and now needs short-term liquidity to bridge the gap between practical completion and the principal releasing the held funds.
Picture a Sydney house builder who finished a single-dwelling contract in March. The principal has paid 95 percent on practical completion. The remaining 5 percent sits as retention, held to the end of the defects liability period roughly six months out. The next contract is signed and starting in two weeks. The builder needs working capital now, and the retention is the cleanest line of sight to repayment, but the funds will not move until the defects window closes.
That is the file a private funder is asked to underwrite. The retention is not the security. The property the builder owns is the security. The retention is the timing story.
What makes a builder retention bridge fundable, and what kills the file
At a structural level, the underwrite splits cleanly into files that pass private credit and files that stall. The pattern is consistent across the funders I work with in this space.
Passes Private Credit
- Practical completion certificate issued and on file
- Principal with a track record of paying retention on time
- Property security with clean equity under LVR appetite
- No active defects or contract disputes
- Builder has the next job lined up or progressing
- Exit strategy mapped to a date inside the funder's term tolerance
Stalls at Credit
- PC not certified, or only verbally agreed
- Principal with a history of disputed final claims
- No real property security, or security already encumbered
- Active defects list still being argued
- Builder between jobs with no forward pipeline
- Exit reliant on retention alone with no plan B
The pattern is not subtle. The files that pass have a property to lend against, a practical completion milestone that is real and documented, and a principal whose payment behaviour does not introduce its own underwriting question. The files that stall ask the funder to take on the principal's behaviour as well as the builder's, and that is not a position private credit is paid to hold.
Exit strategy is the underwrite, not the term
The phrase that matters here is structural. Exit strategy is the underwrite, not the term. A retention bridge is a short-term private bridge, typically 3 to 9 month term, varies by lender, and the term is set to match the principal's release window plus a buffer. But the term is not what is being assessed. The assessment is whether the exit happens cleanly when the term ends.
That is a different question from how a major-bank business loan is read. A bank line is sized to serviceability. A private bridge is sized to exit confidence. Retention is illiquid until release, typically 6 to 12 months post PC, illustrative, and a private funder writing the bridge is essentially betting on that release window being honoured. If the principal pushes the date out, the bridge needs to refinance, sell down to another security, or fall back to the property equity it is already secured against.
This is why the secondary exit matters. A caveat-secured top-up or a refinance to a longer-term facility needs to be available if the retention release slips. Builders who can point to a credible secondary exit, even just a property they could refinance against, see better terms than builders whose only path home is the retention itself. For more on how private credit thinks about exit-first underwriting, the private mortgage borrower decision guide walks through the same framing for property-secured deals.
Where this commonly lands for builders
From the underwrites I have sat across in this corner of the market, where this commonly lands is a property-secured bridge for builders who have a primary residence, an investment property, or a yard with usable equity. The retention release is the headline repayment story, the property is the security, and the term is set around the defects liability period rather than against it.
For builders without spare property security, the file usually pushes into different territory entirely. A second mortgage business loan against the family home, an asset-backed working capital line, or a structured solution that bridges across multiple jobs rather than a single retention. The conversation moves away from the retention as the trigger and into the broader cashflow shape of the construction business.
Builders on the other end of this, those negotiating with funders directly, sometimes ask about borrower protections in the non-bank space. The Australian Financial Complaints Authority process covers credit providers including private lenders and is worth understanding before signing terms with any funder. It is one of the structural reasons we tell builders to work through a broker on private deals rather than approach private credit cold, because the documentation discipline that follows from a brokered file tends to land cleaner on protections, fees, and exit clarity. A read of the caveat loan glossary entry alongside the broader Construction Finance Hub covers the structural pieces most builders are working through when retention bridging comes up.
Retention bridges are a real and recurring liquidity question for builders, especially on residential and small commercial jobs where the held 5 percent sits for months. Private funders can write the bridge, but they do not write it against the retention. They write it against property security, with the retention release providing the exit timing logic. The underwrite is the exit, not the term.
Key takeaway: If retention is your liquidity problem, the structural question is what property security and exit timeline you can offer, not how much retention is being held. Our construction loan pack sets out how the retention bridge sits alongside the primary build facility so the exit reads clean on first review.Frequently Asked Questions
A builder can sometimes borrow against retention money held by the principal, but the loan is rarely secured against the retention itself. Private funders treat retention as illiquid until release and underwrite the bridge against other security, typically a property asset, with the retention release timing forming part of the exit strategy.
The file lives or dies on that exit, not on the retention balance.
Retention typically sits illiquid until release, often 6 to 12 months post practical completion, depending on the defects liability period in the head contract. Private funders use this window as the headline exit timeline, then add buffer for principal payment behaviour.
The window is illustrative and varies by contract.
Private funders on a builder retention bridge almost always take real property security, either as a first or second mortgage, sometimes supported by a caveat. The retention itself is rarely accepted as standalone security because release timing is principal-controlled.
Builders without spare property equity usually find the file harder to place and may need to look at second mortgage business loan structures instead.
How much a builder can borrow against a retention bridge is driven by property LVR and exit confidence, not the retention balance. Funders typically size the facility against available equity in the security property within their LVR appetite, with the retention release providing the timing logic for repayment.
Two builders with identical retention balances can land in very different facility sizes depending on the security property behind them.
What kills a builder retention bridge at credit is usually a weak exit story rather than weak security. Principal payment history, unresolved variations, defects in dispute, or a contract that gives the principal broad discretion on release timing all push the exit out and push the file off the credit committee table.
A clean practical completion certificate, a documented payment schedule, and a credible secondary exit can usually pull the file back into play.
