And the way they check affordability is by poring over your bank statements.

But then, let's say the bank sees a $50-a-week Afterpay payment going out of your account, that’s due to finish in 3 weeks.

The bank won’t say: “Ah, that's payments going to be gone in 3 weeks, so lets include that as income that could be used to pay the mortgage.

Instead, they‘ll look at those payments as if they’ll continue forever. That might sound unfair (and it is) but the bank can’t guarantee you won’t spend the credit again once you’ve finished your repayments.

The bank is going to pick this up when they review your bank statements. So the same rules apply: Tell your mortgage broker up front.

They will front foot any conversations with the bank and give your mortgage application the best shot at being approved.

Don’t forget #7 – revolving credits

A revolving credit is a powerful tool that will help you pay down your mortgage more quickly.

But don’t forget to mention it, as a part of your overall debt when applying for a mortgage. Even if it is unused.

A mortgage broker I spoke to said this was the No.1 most common debt investors forgot to disclose.

Given the fact that revolving credits are popular with investors … this is a big one.

And just like credit cards, and overdrafts, disclosing the debt means the whole amount, not just the amount you’ve got left to pay.

Why? Again, just like a credit card, a revolving credit mortgage lets you draw to the credit limit as many times as you want and can keep doing that as long as you keep paying your balance down. ​

So, the bank has to assume that even though you may have paid off $10,000 of your $50,000 revolving credit – you could potentially take out $40,000 overnight.

Don’t forget #8 – if you’re going to have a baby

Yup, we hear you … how is it my mortgage broker’s business to know when I am planning to have a baby?

As odd as it may sound, it is.

Big changes in personal circumstances can be particularly important if you are buying a new build property. This is because when you buy off-the-plans the construction period is often longer than your finance pre-approval period.

What does that even mean? Well, you as the purchaser have to confirm and go unconditional on the contract before the property is built.

Prior to going unconditional, you’ll get a pre-approval from the bank for your mortgage. This means the bank has assessed your application and said: “Yup, so long as your situation doesn’t change in the next 12 months, will approve this mortgage in 12 months.

But most construction periods run longer than the pre-approval, which means an investor will sometimes need to reapply for finance when it comes to settling.

Here lies the risk: “What if I can’t get my finance re-approved?”

Generally, this risk is only really felt by investors whose life circumstances are about to change. For instance:

  • If you’re about to announce a pregnancy, and you’re about to go from a two-income to a one-income household
  • You’re about to change jobs and your income is expected to decrease
  • You’re about to buy an expensive car on finance.


These changes in circumstances might mean the bank changes its mind about approving your mortgage, and then you’ve got a property you don’t have a mortgage for.

That means you could lose your deposit. Which could mean parting with up to $100,000 (and the opportunity to own a great investment property).

This is why your mortgage broker will sometimes ask you if you have any big life events up-and-coming, including a baby.

What don’t I have to tell my mortgage broker?

Mortgage brokers will often tell you: “It’s always a good idea to tell your mortgage broker everything.

Not because everything is going to be necessary.

But because they are in the best position to make the call as to what they will disclose to the bank or not.

Peter Norris, from  Opes Mortgages, says non-disclosure is really hard to come back from.

“If the bank feels like something is not being disclosed then it’s hard to rectify – even if it’s an accident,” he says.

Unfortunately a deceit, whether intended or not, is extremely hard to come back from – in the bank’s eyes. They will (rightly or wrongly) label you as dishonest and that is very hard to repair.

Which can put a halt on any of your property plans.
