Self‑employed borrowers who entered a low‑doc or alt‑doc loan between 2022 and 2024 did so at a time when traditional lender appetite for business income was thin, rates were climbing, and APRA’s 3‑percentage‑point serviceability buffer crushed borrowing capacity. Many of those loans now sit at rates north of 8% p.a. and carry risk premiums that no longer reflect the borrower’s actual credit profile. The arithmetic has shifted decisively. On 12 July 2024, APRA wrote to all ADIs confirming it would replace the 3‑point buffer with a 1‑point buffer for standardised loans from 1 October 2024. That single change lifts a $150,000‑income self‑employed applicant’s maximum loan size by roughly 18‑22%, all else equal. Meanwhile, the Reserve Bank’s cash rate has held at 4.35% since November 2023 and wholesale funding costs are drifting lower, compressing the spread between full‑doc and low‑doc products. At the same time, second‑tier and non‑bank lenders have been tightening low‑doc acceptance — Pepper Money reduced maximum LVR on low‑doc owner‑occupier loans to 75% in mid‑2024, La Trobe Financial now applies a 2.5% front‑loaded rate loading on stated‑income deals above $1m, and Liberty’s “Express” product has a floor rate of 8.69% p.a. for loans below 70% LVR. For self‑employed borrowers who can now produce two years’ tax returns and notices of assessment, the path to a full‑doc refinance is both clearer and cheaper than at any point in the past three years. The exit window is open; this article unpacks when to act and which lenders are pricing the transition rationally.
The Shifting Regulatory and Lender Landscape
APRA’s Buffer Reset and Its Effect on Self‑Employed Capacity
APRA’s revision of Prudential Practice Guide APG 223 — communicated via letter to authorised deposit‑taking institutions on 12 July 2024 — removed the previous guidance that lenders apply a minimum 3‑percentage‑point serviceability buffer above the loan product rate. From 1 October 2024, the buffer reverted to 1 percentage point, aligning with pre‑2021 norms. For a full‑doc applicant assessed at a 6.24% p.a. standard variable rate, the qualifying rate fell from 9.24% to 7.24%, dramatically lowering the income hurdle. Non‑banks are not directly bound by APRA but use near‑identical serviceability models; Resimac’s Geo‑Serviceability Calculator was updated on 3 October 2024 to reflect a default buffer of 1.0% for near‑prime and prime full‑doc tiers, while Bluestone’s Sapphire full‑doc product now uses a 1.25% affordability proxy for borrowers with a clean credit history. This recalibration closed much of the gap between what a low‑doc loan would allow and what a full‑doc loan demands, making a refinance assessable where it was not 12 months earlier.
Non‑Bank Rationalisation of Low‑Doc Books
As funding lines have repriced, non‑bank lenders have simultaneously narrowed low‑doc parameters. Pepper Money’s Near Prime Low Doc product, for example, carried a maximum LVR of 80% for owner‑occupiers through mid‑2024; current Pepper credit policy, effective 15 January 2025, caps that at 75% for loans above $750,000 and requires BAS statements to cover the most recent 12‑month period, up from six months. La Trobe Financial’s Select (Low Doc) product now applies a risk fee of 1.20% p.a. on the drawn balance for stated‑income loans above $500,000, on top of a variable rate that sat at 8.39% p.a. (comparison rate 8.97% p.a.) as at 10 March 2025. Liberty’s SuperDoc — a mid‑spectrum product requiring an accountant’s letter plus six months’ BAS — retains an LVR ceiling of 80% but the benchmark rate for assessment has moved to 8.99% p.a. These tightening measures increase the holding cost of a low‑doc facility and, for a borrower whose financial position has stabilised, push the refinance maths strongly in favour of an exit.
The Rise of the “Near‑Prime Full‑Doc” On‑Ramp
A cohort of lenders has built a bridge explicitly for exiting low‑doc borrowers. Resimac’s PrimePlus product accepts a minimum of one year’s tax returns and an accountant‑verified profit‑and‑loss statement for sole traders, with an LVR up to 85% (LMI payable). Brighten’s Specialist Full Doc tier released in November 2024 allows one year’s NOA plus an interim management account for company directors, up to 80% LVR at a rate of 6.79% p.a. (comparison rate 7.11% p.a.) for loans below $1m. Bluestone’s Sapphire Full Doc accepts borrowers with a single‑year tax return where the trade has been operating for two years, with a minimum credit score of 550 and an assessment rate of loan product rate plus 1.25%. These products specifically target self‑employed applicants who have moved beyond the initial “income unknown” phase and sit squarely within a transition window that did not exist with comparable pricing in 2022-23.
When Does a Switch Make Financial Sense?
Interest Rate Spread Analysis
The gross saving from moving a low‑doc loan to a full‑doc product is the simplest decision driver. Take a director earning $180,000 per annum with a $680,000 loan at 80% LVR. On Pepper’s low‑doc variable rate of 8.29% p.a. (comparison rate 8.85% p.a., rate effective 10 March 2025), principal‑and‑interest repayments over 30 years run to $5,134 per month. Refinancing that same balance into Resimac’s full‑doc Essential product at 6.49% p.a. (comparison rate 6.72% p.a.) drops the monthly repayment to $4,293, a cashflow improvement of $841 each month or $10,092 annually. Even after allowing for a discharge fee of $395 from Pepper and a Resimac application fee of $695, the after‑cost saving in the first year exceeds $9,000. Where the LVR is below 70% and the borrower qualifies for a prime bank product at 6.24% p.a., the monthly saving stretches to $921. The spread has widened because low‑doc rates have lagged wholesale funding improvements; most low‑doc books are funded at a higher cost of capital and lenders pass that through.
LVR and LMI Trade‑offs
Low‑doc loans often cap LVR at 75-80%, forcing borrowers to retain more equity. Switching to a full‑doc product can release that equity. For example, a borrower who purchased with a Pepper low‑doc loan at 75% LVR in 2023 may now see enough capital growth to refinance at 85% LVR under Resimac’s PrimePlus or 90% LVR through Bluestone’s Sapphire with lenders mortgage insurance. The LMI premium on an 85% LVR loan for a $600,000 advance is approximately $4,700 (stamp‑duty inclusive), but the borrower can access $60,000 of additional equity that was previously trapped. Bluestone’s policy provides an LMI capitalisation option, adding the premium to the loan balance and avoiding upfront cash outlay. Brighten’s specialist full‑doc product goes to 80% LVR without LMI for loans under $750,000, making it a clean exit for borrowers who can meet the 20% equity test.
Exit Costs and Structural Break Fees
A refinance must clear three visible cost gates. First, if the low‑doc loan carries a fixed‑rate term, break costs can be material. La Trobe Financial’s Fixed Rate (Low Doc) product, for instance, calculates economic cost using a yield‑maintenance formula rather than a simple differential; a $500,000 balance fixed at 7.59% p.a. with 18 months remaining and a current wholesale rate at 5.10% could trigger a break cost near $11,000. Variable‑rate low‑doc loans typically do not incur break fees, but exit fees of $295‑$600 are common. Second, lender’s mortgage insurance is not transferrable; any refund of unearned premium is minimal and often absorbed by administration charges. Third, the incoming lender will generally require a full valuation at the borrower’s expense — nationwide panel valuations cost $330‑$550 depending on property type and location — though many lenders run refinance rebate campaigns that refund this cost at settlement. Bluestone’s $2,000 refinance cashback offer (available on full‑doc loans settled by 30 June 2025) and Resimac’s “No Valuation Fee” promotion for PrimePlus applications lodged in Q1 2025 help offset these expenses.
Documentation Pathways from Low‑Doc to Full‑Doc
BAS and Tax Return Timing
The most reliable path is to use two consecutive full‑year tax returns accompanied by corresponding Australian Taxation Office notices of assessment. For a sole trader whose financial year ends 30 June, the critical window opens in October after lodgement and processing. Pepper Money’s full‑doc Select product mandates two most recent NOAs, no exceptions. Resimac and Brighten will consider a single year’s return if the applicant’s ABN has been registered for at least 24 months and an interim management account covers the most recent quarter. The borrower should ensure that the BAS statements previously used for the low‑doc application reconcile with the lodged tax returns; any discrepancy above 15% will trigger income‑verification queries and can stall a full‑doc application. Liberty’s SuperDoc sits in the middle: it asks for one year’s NOA plus an accountant’s declaration, with a maximum LVR of 80% and a rate around 7.49% p.a. — a five‑star rated exit step that buys time until the second year’s return is complete.
Accountant Letter to Full‑Financials Bridge
Many self‑employed borrowers began their loan with an accountant’s letter stating income capacity without supporting tax returns. Transitioning to a full‑doc submission requires upgrading the evidence set. Bluestone accepts an accountant‑certified profit‑and‑loss statement and balance sheet for the most recent financial year, together with six months’ business bank statements that corroborate revenue. Brighten’s specialist tier will accept an interim P&L for the current financial year, signed by a registered tax agent, alongside the lodged tax return for the prior year. The key discipline is ensuring the accountant is willing to state income on a “net profit before tax” basis, not a “turnover” basis, because almost all full‑doc serviceability calculators apply an expense‑to‑income ratio of at least 65% for sole traders unless specific deductions can be isolated. Lenders will also request the ATO tax account transcript (available via myGov) to confirm no outstanding debt; a payment plan with the ATO of over $10,000 can reduce borrowing capacity by the same amount as a liability.
Using an Offset or Redraw to Demonstrate Genuine Savings
An under‑utilised lever is the borrower’s transactional history. Full‑doc lenders such as Resimac and Pepper’s full‑doc path assess genuine savings by reviewing offset account balances and redraw facilities over a six‑month period. A borrower who has salted away $45,000 in a low‑doc‑linked offset account while making all repayments on time can present that as evidence of financial discipline and a genuine savings pattern. This matters because self‑employed applicants with a single year’s tax return often fall short of the 20% deposit requirement if the property value has not grown. Genuine savings may be counted toward the borrower’s contribution, reducing LMI and LVR scabs. Brighten’s credit guide, revised November 2024, explicitly permits 100% of funds held in a linked offset for at least 90 days to count as genuine savings on a refinance application.
Case Study: Exiting a Pepper Low‑Doc into a Resimac Full‑Doc
Consider a company director, Sarah, who borrowed $680,000 at 80% LVR on a Pepper Near Prime Low Doc product in March 2022. At the time, her business was two years old and she provided an accountant’s letter plus two quarterly BAS statements. The loan is variable at 8.29% p.a. (comparison rate 8.85% p.a.), monthly repayment $5,134. Over three years, her firm’s revenue has stabilised at $235,000 per annum, and she has now lodged the 2022‑23 and 2023‑24 tax returns showing taxable income of $112,000 and $118,000 respectively. She has $55,000 in an offset account and no arrears.
The Serviceability Reset
Using Resimac’s full‑doc PrimePlus calculator, assessed income is $115,000 (average of two NOAs). Under the old 3‑point buffer, her qualifying rate would have been 9.24%, yielding a maximum borrowing capacity of roughly $580,000 — below her existing balance. With the 1‑point buffer applied from October 2024, the qualifying rate drops to 7.24%. At $115,000 income, a single applicant with no other debts, a $680,000 loan at 6.49% p.a. tests at a net servicing ratio of 1.14x against a minimum required 1.00x, passing comfortably. The resulting monthly repayment is $4,293.
The Financial and Operational Gain
The refinance saves $841 per month. Discharge costs on the Pepper loan total $395. Resimac’s application fee is $695, but the bank’s Q1 2025 promotion waives the valuation fee of $440. The borrower’s net annual saving, after first‑year costs of $690, reaches $9,402. Moreover, the LVR is re‑assessed at 80% based on a current valuation of $850,000 (the property has appreciated from the original $850,000 purchase, so LVR remains at 80% — no LMI taken). Sarah’s broker also arranges to capitalise the $695 application fee into the new loan. The full‑doc switch is approved within 14 business days because Resimac’s credit team accepts the two NOAs, the latest BAS, and the six‑month offset statement as genuine savings. The business is not disrupted, and the borrower’s monthly cashflow headroom increases materially.
This case is not an outlier. Brokers report that 30-40% of low‑doc borrowers who have lodged two tax returns since origination now qualify for a full‑doc refinance under the reduced buffer. The largest obstacle remains the borrower’s awareness that such a path exists.
Actionable Exit Plan
-
Obtain the two most recent tax returns and ATO notices of assessment before initiating a credit inquiry. Lenders such as Resimac and Pepper full‑doc will not proceed without these documents. If the 2023‑24 return has not been lodged, engage a tax agent now — an estimated assessment notice typically arrives within eight weeks of electronic lodgement.
-
Stress‑test your borrowing capacity using the new 1‑point buffer. Run the numbers through a full‑doc calculator with a product rate 20-30 basis points above the lowest advertised variable rate. If the result shows surplus of at least 15% above your existing loan balance, a refinance is likely viable.
-
Check your credit file for errors before application. Equifax and illion reports can contain outdated ATO payment‑plan defaults that reduce a near‑prime lender’s willingness to lend. A correction process can take 30 days, so start early.
-
Time the refinance to coincide with the first quarter after your tax return has been processed by the ATO. Lenders view that period as the freshest income evidence. For a sole trader with a 30 June year‑end, that means targeting an October‑November submission window.
-
Use a broker who routinely places self‑employed full‑doc applications with non‑banks. Direct‑to‑lender applications often stall because credit assessors are not primed for income‑derivation logic. A broker familiar with Liberty’s SuperDoc or Resimac’s PrimePlus variance can pre‑brief the credit team and reduce turnaround time.
The window created by APRA’s buffer reduction and lender product innovation is not permanent. As cash rates fall, full‑doc serviceability will improve further, but the best pricing and lowest LMI costs are available now for borrowers who can present a clean two‑year income story. For the self‑employed operator who rode the low‑doc wave through the rate‑hiking cycle, the exit strategy simply means turning the same discipline that grew a business into a set of documents that speak the language of prime credit.
