Current Interest Rate Comparison: Low-Doc vs Full-Doc Home Loans in Australia

Self-employed borrowers and small-business owners watching the rate cycle have seen a sharp divide widen between what a salaried applicant pays and what a low-doc borrower is charged. The Reserve Bank held the cash rate at 4.35% for a ninth consecutive meeting in February 2025, with its Statement on Monetary Policy confirming that services inflation remains sticky and that “the path to the midpoint of the inflation target will be gradual.” That persistent cost environment keeps funding margins elevated for non-bank lenders, which dominate the alt-doc sector. Yet the gap is not uniform. On 3 March 2025, Brighten Home Loans reduced its Specialist Alt Doc variable rate for loans above $500,000 with an LVR of 70% or less by 25 basis points, bringing it to 6.99% p.a. That single pricing move, communicated to aggregators, marks the first time a mainstream low-doc product has cut through the 7.00% threshold since the rate-hiking cycle began. For the sole trader who has been putting off a refinance or the company director sitting on a 2022-issued facility, the shift changes the arithmetic. It does not mean the low-doc premium has disappeared—borrowers without full financials are still funding a higher risk weight—but it signals that competitive pressure among the non-banks is starting to compress the spread in higher-LVR, well-documented alt-doc segments. This article maps the current pricing terrain across the major low-doc lenders, breaks the rate spread by LVR tier and documentation type, and isolates the serviceability buffers that, more than the headline rate, often determine whether a loan proceeds.

The Rate Spread: Low-Doc vs Full-Doc Benchmarking

Variable-Rate Products

Across the six lenders reviewed—Pepper Money, La Trobe Financial, Liberty, Resimac, Bluestone, and Brighten—the variable rate on an owner-occupied principal-and-interest low-doc loan with an LVR at or below 60% sits in a band from 6.89% p.a. to 7.99% p.a. In the same week, a major bank basic full-doc variable for an employed applicant with an equivalent loan size and LVR is available from 6.09% p.a. (Westpac Flexi First Option, comparison rate 6.33% p.a., as at 10 March 2025). That puts the absolute spread at 80 to 190 basis points, depending on the lender and the completeness of the income verification.

The narrowest gap is now held by Brighten’s Specialist Alt Doc product, priced at 6.99% p.a. (comparison rate 7.25% p.a.) for an LVR of no more than 70% when the borrower supplies full company financials and an accountant’s declaration. Pepper Money’s Alt Doc Essential—which accepts BAS statements alone—starts at 6.89% p.a. (7.12% p.a. comparison rate) but only goes to an LVR of 60%. As soon as the LVR moves above 60% or the income source relies on a single year’s trading statements, the Pepper rate lifts to 7.29% p.a. La Trobe Financial’s Low Doc Lite occupies a similar tier at 7.49% p.a. (7.75% p.a. comparison rate) for an LVR ≤ 70%, and Liberty’s FreeThinking self-employed loan sits at 7.19% p.a. (7.44% p.a. comparison rate) up to the same 70% LVR cap. Resimac’s Specialist Alt Doc and Bluestone’s Near Prime Alt Doc price further out at 7.49% p.a. and 7.99% p.a. respectively, reflecting LVR tolerance up to 80% and less stringent credit history criteria.

For the self-employed borrower, the headline rate is only part of the decision. The comparison rate, which incorporates upfront and ongoing fees, can widen the effective cost by 20 to 35 basis points. Pepper’s Essential product, for example, carries no application fee and a zero ongoing monthly administration charge for its low-doc option, keeping the comparison rate tight against the headline. La Trobe adds a $990 application fee and a $10 monthly service fee, which pushes its comparison rate to 7.75% p.a. at the top of the LVR range.

Fixed-Rate Options

Fixed-rate low-doc loans remain scarce. Brighten is one of the few lenders offering a 1- to 3-year fixed term on its Specialist Alt Doc product, with the 2-year fixed rate currently at 6.79% p.a. for an LVR ≤ 70%, a 20-basis-point discount to the variable. Resimac provides a fixed-rate add-on through its Select product but only for alt-doc borrowers who supply two years of full financials, effectively moving the loan into near-prime territory. The general absence of fixed-rate choice means most low-doc borrowers operate in a variable-rate environment, making them fully exposed to any further RBA adjustments—and to the lender’s discretion on out-of-cycle changes. Bluestone and La Trobe do not offer fixed rates on alt-doc loans at all.

Comparison Rates and Fees

A comparison-rate table drawn from the lenders’ key fact sheets, all current as of 1 March 2025, shows the spread:

The gap between headline and comparison rates is smallest at Pepper and largest at Bluestone, reflecting the latter’s $660 application fee and annual $395 service charge. For a $500,000 loan over 25 years, a 30-basis-point difference in comparison rate adds roughly $22,000 in total interest and fees. Borrowers comparing offers strictly on headline rate can be misled by as much as 0.35% once establishment costs are folded in.

Lender-by-Lender Breakdown

Pepper Money

Pepper’s Alt Doc Essential product, repriced on 15 January 2025, is the only mainstream low-doc loan to sit below 7.00% for a BAS-only income pathway. The 6.89% p.a. rate applies to owner-occupied purchases and refinances with an LVR ≤ 60%, a clean credit file, and a minimum loan size of $150,000. Borrowers must supply a registered BAS statement covering the most recent 12-month period. Pepper does not use the accountant’s letter as primary verification; it will accept one as supplementary evidence only. The maximum DTI is 6.0x, calculated on the BAS-derived gross income discounted at 20%. For loans between 60.01% and 70% LVR, the rate rises to 7.29% p.a., and above 70% the product is not available. There is no offset account, but a redraw facility is included. The buffer Pepper applies when assessing serviceability is the product rate plus 2.00%, which on the 6.89% rate translates to an assessment rate of 8.89%.

La Trobe Financial

La Trobe’s Low Doc Lite product accepts an accountant’s letter confirming net profit before tax, sourced from business activity statements or company financials. The 7.49% p.a. rate applies to LVRs up to 70% for owner-occupied loans; cash-out is permitted to 70% LVR with an additional 0.20% loading on the rate. La Trobe imposes a minimum credit score of 600 and a DTI ceiling of 5.5x assessed income. Approved applicants can access a 100% offset account linked to the loan. La Trobe’s serviceability test uses the higher of the product rate plus 2.50% or a 7.50% floor, which means that even when the headline rate is 7.49%, the assessment is run at 9.99%. This buffer is the toughest among the non-bank low-doc suite and frequently restricts borrowing capacity for sole traders whose stated income is close to the minimum required.

Liberty Financial

Liberty’s FreeThinking self-employed product is the most flexible in terms of credit impairment—it accepts defaults and paid-out judgments, subject to LVR reduction. Where credit history is clean and the LVR is ≤70%, the variable rate is 7.19% p.a. Liberty does not tier by LVR below that threshold. Income verification uses a 12-month BAS statement or an accountant’s letter; the stronger the documentation, the more likely Liberty will allow an LVR up to 80%, at which point the rate becomes 7.99% p.a. Liberty’s DTI cap is 6.5x, the highest among the non-bank low-doc lenders. The serviceability buffer is product rate plus 2.00%, applied to after-tax income after deducting a 30% living-expense benchmark. A full offset account is available for a $10 monthly fee.

Resimac

Resimac’s Specialist Alt Doc caters to borrowers with LVRs up to 80% for owner-occupied and 70% for investment. The 7.49% p.a. rate for an LVR ≤70% requires either a 12-month BAS or accountant’s letter; for LVRs between 70.01% and 80%, Resimac adds a 0.30% risk margin, lifting the rate to 7.79% p.a. Investment loans carry a further 0.15% premium. Resimac uses a buffer of product rate plus 2.25%. Its living-expense model is a hybrid—it benchmarks the Household Expenditure Measure at the higher of $1,750 per month for a single applicant or $2,500 for a couple but will override if the borrower’s self-declared expenses are higher. The maximum DTI is 5.5x, which means even at a 7.49% rate the gross-income multiple can become binding before the serviceability buffer does.

Bluestone

Bluestone’s Near Prime Alt Doc loan is priced from 7.99% p.a. for an LVR up to 75%, with no rate reduction for lower LVRs. Bluestone accepts BAS statements alone but applies a manual credit assessment that scrutinises bank statement conduct. The DTI limit is 5.0x, the most conservative in the segment. The serviceability buffer is product rate plus 2.50%, identical to La Trobe. The product carries a $660 application fee and $395 annual service fee, and an offset account is not offered. Bluestone therefore sits at the upper end of both rate and fee structures; its main advantage is its willingness to accept borrowers with recent credit defaults or an ABN registered less than 12 months.

Brighten

The recent 25-basis-point reduction on Brighten’s Specialist Alt Doc fixed the variable rate at 6.99% p.a. for owner-occupied loans with an LVR ≤70%, a loan size of $500,000 or greater, and full financials verified by an accountant. BAS-only applications from the same borrower attract a rate of 7.29% p.a., while LVRs above 70% to a maximum of 80% cost 7.59% p.a. Brighten’s DTI cap is 6.0x, and its serviceability buffer is product rate plus 2.00%. This combination—a sub‑7.00% headline rate, a 2.00% buffer, and a DTI ceiling of 6.0x—gives Brighten the highest net borrowing capacity for a well-documented low-doc applicant among the six lenders reviewed. The lender’s February 2025 Statement on Monetary Policy-informed pricing notice also removed the $295 annual package fee for loans above $750,000, lowering the comparison rate to 7.25% p.a.

LVR and Loan Purpose: How Risk Tiers Shape Pricing

The 60% LVR Sweet Spot

Every low-doc lender grants its best rate at an LVR of 60% or lower. At this tier, the lender’s loss-given-default exposure is materially reduced, and the pricing reflects it. For the self-employed borrower with a 40% deposit or equivalent equity, the rate premium over a full-doc major-bank loan can be as little as 80 basis points. In concrete terms, a borrower drawing $500,000 at 60% LVR on Pepper’s 6.89% p.a. product pays $3,486 per month. The same loan size on Westpac’s 6.09% p.a. basic variable product costs $3,250 per month—a $236 difference that buys a pathway that does not require two years of tax returns or employer payslips.

Once LVR crosses 70%, most lenders impose a rate loading of 20 to 40 basis points. La Trobe, for instance, does not vary its rate for LVRs between 60% and 70%, but Resimac and Brighten add 0.30% and 0.30% respectively. At 75% to 80% LVR, lenders such as Bluestone and Resimac also begin to require lender’s mortgage insurance on low-doc loans, an additional capitalised cost that pushes the effective rate higher.

Investment vs Owner-Occupied

All six lenders price investment loans at a premium. The typical loading is 0.15% to 0.30% above the owner-occupied rate for the same LVR and documentation tier. Brighten’s investment rate on the Specialist Alt Doc product sits at 7.29% p.a. for an LVR ≤70%, a 30-basis-point differential. Interest-only terms are generally unavailable on low-doc investment loans; only Liberty and La Trobe allow up to five years interest-only, and then only at an LVR ≤60% with an additional 0.25% pricing margin. For the investor using a low-doc product, the all-in rate can therefore reach 8.24% p.a. (Bluestone Near Prime Alt Doc, 75% LVR, interest-only), making the cash-flow hurdle high enough that many brokers steer clients toward an asset-lend structure instead.

Cash-Out and Debt Consolidation

Low-doc loans with cash-out carry two penalties: a rate loading and often a lower maximum LVR. La Trobe permits cash-out to 70% LVR at a 0.20% loading, taking its owner-occupied rate to 7.69% p.a. Resimac reduces the maximum LVR for cash-out to 65% and applies no loading, but its 7.49% p.a. rate already sits above the market. Where the cash-out is for business purposes, lenders will require a letter from the borrower’s accountant stating the funds are for a defined business need, and if the purpose is ATO debt consolidation, additional conditions apply: Pepper will only capitalise ATO arrears when the borrower provides a formal payment arrangement, and Liberty requires the arrears to be less than $50,000. These constraints mean that the effective rate spread for a cash-out low-doc loan often exceeds 200 basis points over a standard full-doc cash-out product, and the borrower must factor that into working-capital cost calculations.

Serviceability Buffers: The Hidden Cost Hurdle

APRA’s 3% Buffer and Alt-Doc Adjustments

APRA’s Prudential Standard APS 220 requires authorised deposit-taking institutions to assess home loan serviceability at the product rate plus 3.00% per annum, or a minimum floor rate, whichever is higher. Non-bank lenders, including the six in this review, are not directly bound by APRA’s standard, yet most mirror a similar structure with adjustments. The difference is crucial: an alt-doc applicant assessed at a buffer of 2.00% above the product rate faces a materially lower hurdle than a full-doc applicant at 3.00%, all else equal. A self-employed borrower on a Brighten product at 6.99% is tested at 8.99%; a PAYG peer with the same loan amount at a major bank’s 6.09% is tested at 9.09%. The serviceability stress is almost identical. However, when the low-doc product uses a buffer of 2.50%—as La Trobe and Bluestone do—the assessment rate jumps to 9.99%, which at current rates can cut borrowing capacity by 15–20% relative to a 2.00% buffer, based on standard amortisation assumptions.

How Banks and Non-Banks Differ

The major banks do not generally offer a standalone low-doc product to new customers; where they do, through their specialist lending arms (Westpac’s Alt Doc via RAMS, for instance), the buffer is typically 2.50% to 3.00%. The non-bank sector, therefore, creates an opening for the self-employed precisely because it operates with lower buffer requirements. Liberty and Brighten with a 2.00% buffer serve the risk window that banks have vacated. The buffer, not the headline rate, explains why a borrower who files an accountant’s letter showing net profit of $150,000 will often be approved for a higher loan amount at Brighten than at a bank offshoot, even though Brighten’s nominal rate is 90 basis points higher.

Living Expense Benchmarks

Serviceability also depends on how living expenses are treated. Non-bank low-doc lenders tend to use the Household Expenditure Measure (HEM) but will override it with declared expenses if higher. Resimac applies a minimum HEM of approximately $21,000 p.a. for a single, $30,000 p.a. for a couple. Liberty benchmarks at 30% of gross income, which for a high-income sole trader can exceed HEM and become the binding constraint. Self-employed borrowers who keep personal expenses low relative to income should favour lenders that allow a HEM floor rather than a percentage-of-income method. The interplay between income verification method (BAS, accountant letter, or full financials), the buffer, and the expense treatment defines the real borrowing ceiling far more than the sticker rate.

When the Premium Disappears: Pathways to Full-Doc Pricing

Alt-Doc with Full Financials

The rate premium narrows significantly when the borrower provides two years of full financials, even if the business structure is complex. Brighten’s 6.99% rate and Liberty’s 7.19% rate both apply to what is effectively an alt-doc loan that meets near-prime documentation standards. By supplying company tax returns, profit-and-loss statements, and an accountant’s letter, the self-employed borrower essentially trades away the low-doc label and accesses rates within 80–90 basis points of a prime full-doc rate. For a director with a profitable company but a modest personal salary, this is the cheapest route to competitive pricing.

Accountant Letter vs BAS-Only

The documentation type itself changes the rate. At Pepper, the gap between BAS-only at 6.89% (LVR ≤60%) and BAS at 60.01–70% LVR is 40 basis points. At Brighten, the difference between full financials (6.99%) and BAS-only (7.29%) is 30 basis points. The accountant’s letter, when accepted as a primary document, typically secures the lower tier rate across La Trobe and Liberty. For borrowers who can produce a simple profit-and-loss statement certified by a registered tax agent, the cost of obtaining that letter—usually $150–$300—is quickly recouped in lower monthly repayments and higher borrowing capacity.

Using Asset Lending to Bypass Income Assessment

For self-employed borrowers with substantial equity in the security property, an asset-lend structure can remove the low-doc premium entirely. Resimac’s Specialist Asset Lend product, for example, prices from 7.19% p.a. at 60% LVR with no income verification required; the loan is approved solely on the property’s value and the borrower’s demonstrated ability to service the debt from all sources, including business cash flow disclosed via bank statements. That rate sits 30 basis points below the same lender’s standard alt-doc rate and effectively matches the Brighten full-financials low-doc rate. While asset-lend LVRs are capped at 65% and the product is not available for construction or vacant land, for a refinance of an existing owner-occupied property with significant equity it offers the most direct route to full-doc-equivalent pricing.

The premium that low-doc borrowers pay is not a single number; it is a function of LVR, documentation quality, loan purpose, and the lender’s serviceability buffer. To act on this comparison, the self-employed applicant should first secure an accountant’s letter and two-year financials where possible—that documentation alone can remove 30 to 40 basis points from the rate at Brighten, Liberty, and La Trobe. Second, where the LVR allows, target the 60% or lower tier; Pepper and Brighten both price at or below 7.00% in that window, and the monthly repayment gap over a full-doc loan shrinks to less than $240. Third, pay attention to the comparison rate, not the headline. A Bluestone headline of 7.99% becomes an effective 8.22% once fees are loaded, and on a $500,000 loan that difference is worth roughly $1,100 in the first year alone. Fourth, run the serviceability numbers on the buffer the lender actually uses: a La Trobe assessment at 9.99% will yield a lower maximum loan than a Liberty assessment at 9.19%, even if the headline rates are close. Finally, for those with sufficient equity, the asset-lend pathway at Resimac or a similar lender should be tested before accepting any low-doc variable rate above 7.50% p.a. The market is moving, and the March reduction from Brighten is the first signal that non-bank competition is translating into real relief for self-employed borrowers who can document their income thoroughly.
