With Kip the brain

How I think about a loan

A loan is one decision inside a longer plan. Before I recommend anything, I want to know what you're likely to do next, whether that's selling, upgrading, buying another property or renovating.

Then we set the lending up so those options stay open, and we talk through the risks now and a few years out.

Doing that well means knowing what lenders will actually do, and that changes all the time. I meet regularly with lenders' business development managers and read their policy updates as they come out. I also hear from the real estate agents and buyers agents I work with about what's happening in the market week to week.

Often it's a new or little-known policy that makes a deal work. There's an example just below.

I pride myself on answering quickly, whether the answer is yes or no.

The game plan

Real clients, real moves

At the time, a client could see property values starting to lift and wanted to buy several investment properties before they did.

They wanted to keep their home loan where it was, because the rate was very hard to beat at the time. Their income had also gone up recently, but lenders couldn't use the new figure until the next tax return was done.

Timeline: 2025 to 2026

Scroll to play it out

  1. BonusA policy most people hadn't noticed at the time.

    Move 1

    First investment property

    Bought with their existing bank, using a self-employed policy it had recently launched at the time, which looked at one year of income instead of two.

  2. BonusHome loan rate left alone.

    Move 2

    Second property

    Same bank and same policy, settled soon after the first.

  3. ChanceBackup plans ready if anything changed.

    Move 3

    Third property

    The higher income wasn't usable yet, so this one went through a low doc loan, with a plan to refinance once the tax return was in.

  4. PaydayValues lifted, as expected.

    Move 4

    The refinance

    Once the tax return was done, the low doc loan moved across to the main bank. The properties had grown quickly since purchase, so we also released equity for the client's next plans.

We planned all of it months in advance, using what we knew at the time, with backup plans in case anything changed.

Details kept general so clients can't be identified. Rates, lender policies and market conditions were as they stood at the time and may have changed since. Every situation is different and lending criteria apply.

How I can help

Home and investment loans

First home buyers

Deposits, grants, guarantees and pre-approval, explained in plain English. You might be closer than you think. First home buyer loans

Upgrading or downsizing

Moving to your next home, including buying before you've sold. I'll walk you through bridging finance, a longer settlement or buying subject to sale, and what each would mean for you. Bridging loans

Investment loans

Your first investment property or the next one in a portfolio, set up with the purchase after this one in mind. I also review how existing investment loans are structured. Investment loans

Refinancing

If your loan hasn't been looked at in a couple of years, it's worth fifteen minutes to check it against the market. That includes releasing equity for renovations or the next purchase. Refinancing

Construction

Land and build, knockdown rebuilds and progress payments, managed so the build keeps moving. Construction loans

Self-employed and complex income

Self-employed, bonuses and commission, or income earned overseas. Lenders treat these very differently, and matching you to the right policy is the job. Self-employed home loans

Doctor, nurse, teacher, lawyer or accountant? Many lenders will let you borrow up to 90%, and doctors up to 95%, without paying LMI. Home loans for professionals

Commercial and business

Asset finance

Vehicles, equipment and machinery to grow the business without tying up cash flow. Asset finance

Business loans

Starting, expanding or smoothing out cash flow, with lending that fits where the business is headed. Business loans

Three steps, no homework

How it works

  1. 1

    A 15 minute chat

    We talk about where you are and where you want to get to. You don't need any documents for this, and there's no obligation.

  2. 2

    I compare lenders

    I run your situation past more than 60 lenders and come back with a recommendation and my reasons for it.

  3. 3

    I take it to settlement

    I prepare the application, deal with the lender and keep you updated until the loan settles. You can save your energy for choosing paint colours.

Send an enquiry and I'll get back to you within one business day. After settlement, I check in over the first couple of months and review your loan every 12 months.

The full process, step by step
  1. The 15 minute chat. You tell me the goal and I test it on the spot against borrowing capacity tools and property data.
  2. Your documents. Payslips, statements, ID and a fact find, all through a secure portal in one go.
  3. A shortlist. I re-run everything with verified figures and narrow it down to the lenders whose policy fits you.
  4. Pricing and valuations. I ask the shortlist for rate discounts and order valuations, since either can change which lender comes out ahead.
  5. Your decision. I call you, we talk it through and you choose. Nothing moves without your okay.
  6. The application. I prepare the comparisons, compliance checks and the lender's own forms so you can sign everything electronically at once.
  7. Lodgement. I submit it, check in on the lender's turnaround and handle their questions.
  8. Approval to settlement. Loan contracts, insurance and the final details, sorted with you through to settlement day.

Jason Birks, mortgage broker at Birks Financial Group, Brisbane

Nice to meet you

About me

I spent over ten years as a mobile lender with Westpac and NAB before starting Birks Financial Group in 2025, and I'm a member of the FBAA.

I grew up on Brisbane's northside and live on the southside now.

At home I have two young kids, so weekends are mostly family time, picnics and outings.

Brisbane, the Sunshine Coast and beyond

Brisbane's northside and southside, and the Sunshine Coast where most of my extended family lives, are the markets I know best. I also hear from the agents and buyers agents I work with every week about what's happening in them. You don't need to live nearby, though. Everything works over phone and video, and I have clients across Australia.

What clients say

Questions people ask

What does a mortgage broker cost?

For almost all home loans, nothing. The lender pays me a commission when your loan settles, and I tell you exactly what it is. You'd pay the same rate going to the bank directly, but you'd only see that one bank's options.

Why not just go to my own bank?

Your bank can only offer its own products. If its policy doesn't suit your situation the answer is no, even when other lenders would say yes. I compare more than 60. Mortgage broker or bank?

How much deposit do I need for my first home?

It depends on the lender and the price. Many lenders want 20% to avoid lenders mortgage insurance, but there are options with less, including government schemes for eligible first home buyers. I'll tell you which ones you qualify for.

How long does pre-approval take?

It depends on the lender and how quickly I get your documents. A few days to two weeks is typical, and I'll give you a realistic timeline up front.

Do I have to sell my home before I buy the next one?

No. Bridging finance, a longer settlement or buying subject to sale can each let you buy first. Which one suits depends on your equity, your income and how quickly your current home is likely to sell.

Can I use the equity in my home or investment property to buy another one?

Often, yes. If your property has grown in value, you may be able to borrow against that equity for the deposit and costs on the next one. How much depends on the valuation, your income and each lender's policy, so I check all three before you start looking.

How often should I review my home loan?

Every year or two is a good habit, and any time your situation changes or a fixed rate is about to end. For my clients I do it automatically: I review every loan 12 months after it settles to make sure it's still competitive.

I'm self-employed or my income is unusual. Can you help?

Yes. Lenders treat income very differently from each other, and matching your situation to the right lender's policy is a big part of what I do.

Do you help with commercial and business loans?

Yes. I arrange commercial property loans, asset finance and business loans. The process is a little different from a home loan, and I'll explain what lenders will want to see before you apply.

Do you only work with Brisbane clients?

No. Brisbane and the Sunshine Coast are the markets I know best, but everything works over phone and video, and I have clients across Australia.
