The best investment loan rates are the ones that fit your deal
What sets your investment loan rate, the indicative ranges by structure, and how a broker reaches the best investment loan rates across a panel of lenders.
The best investment loan rates are not a single advertised number. They are the lowest rate a lender will actually approve for your property, your structure, and your serviceability position. Indicative rates run roughly 6% to 8% per annum on prime residential investment lending. Alt-doc, complex trust or company structures, and specialised commercial security price higher. Where you land depends on your LVR, your security, how your income is verified, and which lender you reach.
Windsor Finance is a finance broker, not a lender. We hold no own capital and approve nothing. We take your deal to a panel of Australian bank and non-bank lenders, then place it with the one offering the best structure for your numbers. That is how you reach the keenest rate a lender will genuinely write, instead of accepting the one rate your own bank happens to quote. Every figure here is indicative; the lender confirms on application.
Investment lending prices on the borrower, the security, and the structure. A clean prime deal sits at the bottom of the range. Anything the major banks find awkward sits higher, because fewer lenders will write it. Prime residential investment lending runs roughly 6% to 8% per annum, cheapest at lower LVR, with full income documentation and standard metropolitan security. Alt-doc and low-doc investment lending runs higher, commonly 7% to 11% per annum, reflecting income verified through BAS, accountant letters, or business bank statements. Commercial investment property runs roughly 6% to 9% per annum, with strong covenant and low LVR at the lower end. Two investors can buy near-identical properties and pay very different rates. The difference is rarely the property. It is the LVR, how income is evidenced, the ownership structure, and the lender chosen.
Lenders set your rate on the risk in front of them, and four levers do most of the work. Your LVR is the largest single factor, standard residential investment runs up to around 80% of value, Lenders Mortgage Insurance generally applies above 80% and adds real cost, and dropping to 70% or 65% usually improves the rate with it. Your serviceability matters next: every lender applies its own buffer to your existing debt and the new loan, investor buffers are tighter than owner-occupier ones, and a lender whose buffer suits your position prices you keenly while one already near its ceiling either declines or prices defensively. How your income is documented shapes the rate, full tax returns and notices of assessment earn prime pricing, while income verified through BAS, an accountant’s letter, or business bank statements (common for self-employed investors) steps the rate up to reflect the reduced verification. Your security and structure set the lender pool: standard residential or commercial property prices well, specialised, regional, or non-standard security narrows the pool and lifts the rate, and company and trust structures are fine but not every lender prices them the same.
Headline rates are written for the cleanest borrower at the lowest LVR with full documentation. If your file has any complexity, that advertised rate is not the rate you will be offered. The better target is the lowest rate a lender will actually approve. A 6.4% loan that settles beats a 5.9% rate you never qualify for.
The interest rate is not the whole cost. Investment facilities carry lender and third-party fees, all paid to the lender or provider rather than to Windsor: an establishment or application fee, a valuation fee, legal and settlement costs, and Lenders Mortgage Insurance where the loan sits above 80% LVR. Compare quotes on total cost, including fees and any LMI, not the headline rate alone. A slightly lower rate at 85% LVR with LMI attached can cost far more than a marginally higher rate at 78% with no insurance. We set out the full cost in writing before you commit, including how Windsor is paid.
Walking into your own bank gets you one investment product and one buffer. If your deal fits that single box, fine; if it does not, the answer is a higher rate or a decline. A broker checks the whole panel at once: one enquiry reaches banks, near-banks, and non-bank lenders with different serviceability rules, different LVR limits, and different views on company and trust structures, so you see the keenest rate that works for your file rather than the only one your bank sells. We hold no balance sheet, so there is no product to push. The recommendation follows your deal. We also package the file so the lender’s credit team sees a clean case first time; a file that bounces between lenders wastes days and can mark your credit record, which lifts your pricing.

Cost calculator
When this fits
Full income documentation, standard metropolitan security and a sub-80% LVR, the bottom of the range, no LMI.
Income evidenced through BAS, an accountant’s letter or business bank statements prices higher, so a broker finds the lender that suits it.
A company or trust holding your deal does not fit one bank’s single box, so a broker takes it across the panel to a lender who prices it.
