• Low-doc funding may reach around $500,000 for established operators
• Existing debts and short ABN history can cap your capacity
• One application across 80+ lenders reveals your true borrowing range

What determines your borrowing capacity?

Your limit is a judgement each lender forms from your trading history, cash flow, existing commitments and the value of the asset. A hydro excavation truck's value sits well above a plain vehicle because the vac system, pump and tanks count too, which can support a larger loan when documented. Lenders lend against both the asset and your ability to service repayments, so an established civil operator with steady contracts sees a higher ceiling than a newcomer. As a broad guide, funding across a lender panel can range from tens of thousands for a modest used unit up to $10M-plus for fleets, all indicative and subject to lender criteria. The workable figure is what your project income can comfortably repay while the truck earns.

Does the vac system lift the amount?

Generally yes, since it forms part of the asset's documented value. A hydro excavation build's high-pressure pump, water tanks, vacuum blower, debris tank and hydraulics can represent a large share of the total cost. When you buy a turnkey truck or supply clear invoices for a vac body fitted to a chassis, lenders can include that value in the financed amount. The requirement is verification: a lender advances against worth it can confirm through invoices or a valuation. Well-documented vac equipment therefore lifts your borrowing on the asset, while undocumented modifications are harder to value and fund. A broker can tell you which lenders on the panel are comfortable financing vac bodies at full value and which take a more conservative line on specialist gear.

How do civil contracts affect the amount?

A defined contract shows a lender where repayments come from, and that visibility can support a higher approved amount, especially for newer operators or larger loans. If you hold ongoing agreements with utilities, civil contractors or councils for non-destructive digging, their length and value help the lender see the cash flow behind the borrowing. Contracts alone don't guarantee capacity, since projects end, but they strengthen the picture, and operators with work spread across several clients read as lower risk. For eligible applicants, contract-backed cash flow combined with a clean ABN history may unlock both a higher ceiling and sharper indicative terms. A broker knows which lenders lean most on civil contracts when sizing a loan and frames your pipeline accordingly.

Where does low-doc fit in?

Low-doc lending lets established operators borrow without full financial statements, relying on bank statements, BAS or an accountant's declaration. For eligible applicants, low-doc funding may reach around $500,000, which covers many single vac trucks including their system and tanks. Lenders offset the lighter paperwork by looking for a clean ABN history, a reasonable deposit or a strong asset. If your truck sits above the low-doc band, or you want the keenest indicative rate, full financials generally unlock higher amounts. A broker can tell you upfront whether your target truck fits inside low-doc or whether supplying returns will serve you better, so you apply the right way and avoid wasting an enquiry on a path that won't reach the figure your build requires.

What can limit your borrowing power?

Several factors quietly reduce the ceiling. Existing vehicle or equipment loans lower serviceability, since lenders count those repayments against you. A short ABN history, gaps in GST lodgement, ATO arrears or recent defaults all weigh on the assessment and may cap the amount or raise the indicative rate. Buying an older, high-hour vac truck can also limit borrowing because the security is worth less. Working in your favour, consistent BAS, a clean credit file and a clear contract pipeline strengthen the case. If your numbers are borderline, a broker may suggest practical steps, such as clearing a small debt or timing the application after a strong quarter, to help you reach the amount your vac truck requires.

How does comparing lenders help?

Borrowing capacity is a decision that varies from lender to lender, and on specialised assets like vac trucks the spread is wide. One bank may cap you on trading time or hesitate over the vac body, while a non-bank lender funds the full asset on cash flow and its documented value. Overdrive Truck Finance submits one application across 80+ banks and non-bank lenders and identifies which will advance the amount you need on suitable terms. That avoids applying to a single lender, being capped low or declined, and marking your credit file with repeat enquiries. The outcome is an honest picture of your real borrowing power and an indicative rate reflecting the best fit for your hydro excavation truck.

Before you commit to a vac truck or a build budget, it helps to know what you can genuinely borrow. Overdrive Truck Finance can run your profile across 80+ lenders on one application and give you an obligation-free quote, using a soft credit check that leaves no mark on your file. For eligible applicants, indicative decisions often land within 24 to 48 hours, so you can spec your hydro excavation truck around a real number.
