Thinktank isn’t a household name, and that’s deliberate. It’s a specialist property lender that brokers reach for on the deals mainstream banks handle badly: SMSF purchases, commercial property, and self-employed investors. It’s not a mainstream home-loan pick, and we won’t pretend otherwise; if you’re a straightforward first home buyer wanting the cheapest owner-occupier loan, this isn’t your lender. But if you’re buying an investment property through your super fund or a commercial premises for your business, Thinktank is well worth understanding. Below we cover what they’re good at, where they fall short, the products, the documents, borrowing considerations, approval timing and who they actually suit.
Thinktank is a strong pick for SMSF and commercial property, and a weak one for everyday home buying. Its genuine edges (SMSF structures most lenders decline, commercial property depth, and mid-doc verification for the self-employed) are real and hard to match. But it’s not built for low-deposit owner-occupier lending, and a vanilla PAYG home buyer will almost always do better at a mainstream bank. Match the lender to the job, not the other way around.
Note: this review is current as of 10 July 2026 and product/policy information is subject to change without notice. We don’t publish interest-rate figures here, as pricing for SMSF, commercial and residential deals varies by structure and risk, and dates quickly. Thinktank lends through mortgage brokers, not branches. Any credit application is subject to the lender’s criteria and final approval; we confirm current terms directly with Thinktank before you apply.
Who is Thinktank?
Thinktank is one of Australia’s leading non-bank property-lending specialists. It began in commercial lending, added SMSF lending in 2013, residential loans in 2018 and private lending in 2024. It now spans the full property-finance spectrum with a distinctly investor- and business-focused lens. Like other non-banks it lends exclusively through brokers and funds its loans via the capital markets rather than customer deposits. Where most lenders on this list are built around the everyday owner-occupier, Thinktank’s centre of gravity is investment, SMSF and commercial property, and that shapes everything from its credit assessment to its product design.
What is Thinktank good at?
- SMSF lending done properly.They handle complex fund structures (tenants in common, in-specie transfers, unit trusts) that many mainstream lenders won’t touch or don’t have the credit expertise to assess quickly.
- Commercial property. Their original specialty since 2006, with genuine depth and appetite for deals a bank credit team would decline on sight.
- Self-employed investors.Full-doc and mid-doc income verification, useful where standard PAYG payslip proof isn’t available.
- Long terms on investment property: up to 30 years, which helps serviceability on commercial and SMSF deals that often come with shorter terms elsewhere.
- A straightforward residential product for owner-occupiers and investors who want a fixed-rate, no-fuss loan without the complexity of the SMSF or commercial range.
Where does Thinktank fall short?
- Not a low-deposit lender. Their focus is investment and commercial, generally at conservative loan-to-value ratios, not the first choice for a 5% deposit first home buyer.
- Not built for owner-occupier rate-shopping. A vanilla home buyer wanting the sharpest headline rate will usually find better pricing at a mainstream bank or a digital owner-occupier lender.
- Minimum security values and loan caps apply. A minimum security property value and maximum loan sizes by location mean smaller or unusual deals may not fit their book.
- No branches.Broker and online support only. There’s no shopfront to walk into if you want a face-to-face conversation.
- Structural complexity cuts both ways.The same SMSF and commercial structures that are Thinktank’s strength also mean these applications really take longer to assess than a plain PAYG home loan. That’s the nature of the deal, not a lender failing.
The real edge: SMSF and complex property
Thinktank’s genuine value sits in two areas most lenders avoid entirely. The first is SMSF property lending, a space many banks have exited, and one where the structures (unit trusts, tenants in common, in-specie transfers) quickly outrun a mainstream credit team’s appetite and expertise. The second is commercial property, their founding specialty since 2006. For a self-employed investor buying through their super fund, or a business owner purchasing their own premises, Thinktank has the products, the appetite and the long loan terms to make deals work that a bank would decline on sight. It’s a specialist tool for specialist jobs, not a general-purpose home loan.
We reach for Thinktank when a deal’s complexity is the problem, not the borrower’s income. An SMSF structure with a unit trust, or a commercial premises a bank’s automated system can’t categorise properly, is exactly where a specialist non-bank earns its keep over a Big Four’s standard credit policy.
Self-employed and mid-doc verification
Thinktank also offers a meaningful policy for self-employed investors: full-doc and mid-doc income verification, which helps where a borrower’s most recent tax return doesn’t fully reflect their trading position, or where standard PAYG-style payslip proof simply isn’t available. It’s not a low-doc lender in the sense of skipping verification altogether. It’s a lender that accepts a wider range of evidence for a truly self-employed income. Combined with their residential product, this makes them a reasonable option for a self-employed investor whose file doesn’t fit a mainstream bank’s box.

Thinktank home loan rates
Thinktank’s pricing reflects the deal type. SMSF and commercial loans are priced differently to standard residential lending, and risk plays a real role in the number you’re offered. Because their deals tend to be structural (fund set-up, property type, term, security value) rather than one flat advertised rate, we don’t publish specific figures here. They date quickly and don’t reflect what a truly complex deal will actually cost.
Getting the structure right matters far more than chasing a headline number. Book a free assessment or call 1300 088 065and we’ll model the true cost of your SMSF, commercial or investment deal against Thinktank and the other specialist lenders on our panel.
What documents does Thinktank need?
Documentation depends heavily on which product you’re applying for, but expect:
- Proof of identity: standard 100-point ID for all borrowers and, for an SMSF loan, the fund trustees.
- Income evidence: full-doc (tax returns, financials) or mid-doc verification for self-employed applicants, depending on the deal.
- SMSF structure documents: trust deed, fund financials and, for complex structures, the unit trust or bare trust documentation.
- Commercial deal documents: lease agreements, property valuation and business financials for commercial-purpose loans.
- Property documentation:the signed contract of sale and your solicitor/conveyancer’s details for a purchase, or a recent loan statement if you’re refinancing.
Because SMSF and commercial deals carry more moving parts, the more complete your file up front, the faster Thinktank can assess it. A broker who’s packaged one of these deals before is a genuine advantage here.
How does approval work with Thinktank?
Complex structures take longer to assess than a plain PAYG home loan. That’s the trade-off for a lender that will actually consider the deal:
- Structure & scopingThe fund set-up (for SMSF) or deal type (for commercial) is confirmed before lodging. This is the step that determines whether the deal fits Thinktank’s parameters.
- Application & assessmentFull-doc or mid-doc income evidence and property/security documents are reviewed. Complex structures really take longer than a standard residential file.
- Approval & settlementOnce approved, loan documents are signed and settlement follows. Timing depends on the deal’s complexity and how complete the file was going in.
There’s no advertised turnaround time we can quote honestly here, because SMSF and commercial timing varies too much deal to deal. A broker who scopes the structure properly before lodging is the single biggest lever on how smoothly it goes.
What else does Thinktank offer?
- Private lending:shorter-term, situational funding added to the range in 2024 for deals that don’t fit a standard term loan.
- Long loan terms: up to 30 years on investment property, useful for strengthening serviceability on SMSF and commercial deals.
- Broker-only distribution: every application is lodged and managed through an accredited broker rather than a branch, which suits investors who already work with a broker for structuring advice.
What are Thinktank customers saying?
As a broker-distributed specialist lender, Thinktank doesn’t have the same retail brand visibility as a bank, so mainstream customer-review volume is limited. In our experience, the borrowers who use Thinktank (SMSF trustees, commercial buyers, self-employed investors) value that the deal gets a genuine assessment rather than an automated decline, and that the broker managing the application can speak directly to Thinktank’s credit team about a complex structure. We haven’t seen enough independent review volume to make a broader claim about satisfaction, and we won’t invent a statistic to fill the gap.
Who Thinktank suits, and who it doesn’t
This is the most important section of this review. Thinktank is a niche specialist, not a mainstream home-loan choice. Fit matters more here than with almost any other lender on our panel.
- Tends to suit
- SMSF property buyers, including complex fund structures
- Commercial property purchasers
- Self-employed investors needing mid-doc verification
- Investors who benefit from long (30-year) terms
- Substantial investment deals in metro areas
- Tends not to suit
- Low-deposit first home buyers
- Owner-occupiers chasing the sharpest home-loan rate
- Small loans or properties below their minimum security value
- Anyone who needs branch access
How does Thinktank compare to other lenders?
Thinktank is best judged against the other property-lending specialists, not the Big Four. Its whole model is built around deals a mainstream bank won’t take on:
| What matters | Thinktank | Broader non-banks | Mainstream banks |
|---|---|---|---|
| SMSF lending | Core strength since 2013, complex structures accepted | Some offer it; fewer handle complex structures | Most have exited the space |
| Commercial property | Founding specialty, genuine appetite | Varies, a handful specialise | Conservative, often via a separate business bank |
| Self-employed / mid-doc | Full-doc and mid-doc verification | Common strength across the segment | Usually full-doc, two years’ financials |
| Low-deposit owner-occupier | Not their focus | Rare | Strong, government schemes, LMI waivers |
| Broker’s take | The standout for SMSF/commercial; wrong tool for a plain home loan | Broader credit-impaired coverage; less SMSF depth | Better for straightforward, low-deposit residential |
Thinktank is more specialised than the broader non-banks like Liberty, La Trobe, Resimac and Bluestone. Where those lenders cover a wide spread of self-employed and credit-impaired residential borrowers, Thinktank’s focus is squarely on SMSF, commercial and investment property. For those specific jobs it’s often the standout; for a standard home purchase it usually isn’t the right tool. A mainstream bank or a self-employed home loan specialist will typically serve you better.
Broker tips for applying with Thinktank
- Get the SMSF structure right first. The fund set-up and property type drive the whole application. Sort these before lodging, not after.
- Check the security minimums and loan caps early so the deal fits their parameters before you go to contract.
- Use their long terms deliberately to strengthen serviceability on SMSF and commercial deals.
- Compare against the other specialists.On some investment files a broader non-bank may still win. Thinktank isn’t automatically the answer just because the deal is complex.
- Don’t use Thinktank for a plain home purchase.If you’re a straightforward PAYG buyer, a mainstream lender will almost always price and service better.
Is a Thinktank home loan right for you?
Thinktank is a strong choice if you’re buying property through an SMSF, purchasing commercial premises, or investing as a self-employed borrower whose file needs mid-doc verification, provided the deal is structured correctly and compared against the alternatives. It’s a poor choice if you’re a first home buyer or a straightforward owner-occupier chasing the sharpest rate; that’s not what they were built for, and we’ll say so plainly. We’ll structure your SMSF, commercial or investment deal and compare Thinktank against 30+ lenders on our panel. Book a free assessment or call 1300 088 065 to get started.
