Top tips for home loan borrowing on a $100,000 salary 

If you’re keen to kickstart your home buying journey today, your first step should be to figure out how much you can borrow from a bank or a credit union. 

How do you work out your borrowing power? It’s simple! All you’ll need to do is to scroll up to Mozo’s calculator above and punch in a few of your personal finance details like your expenses and other loan repayments, your desired loan term and expected interest rate. From there, you’ll be able to see an estimate of your borrowing capacity and your monthly repayments down the track. 

What affects my borrowing power?

  • Your income 

Earning $100,000 a year from your full-time job? This is information lenders will want to know in order to get a sense of how much money you have access to. When it comes to assessing your borrowing power for a home loan, banks will look at your two most recent tax returns. 

But there’s more to the picture. Whether you’re planning to buy a house as a single borrower or a couple also impacts your borrowing power. Here’s a scenario to illustrate this point. 

Let’s say two different households earn the same level of income per year: in the first case, Sally and her partner are both on $50,000 salaries (or a combined salary of $100,000), while in the second case, Samantha alone is on a $100,000 salary. Although their annual incomes are the same, Sally and her partner would have greater borrowing power than Samantha. The couple would be able to borrow $818,752 while Samantha would only be able to borrow $686,181 (or $132,571 less).*

Why? It comes down to the lender’s assessment of your risk. If you’re earning just one income, an unexpected event like losing your job or a serious illness could mean you’re suddenly unable to make your mortgage repayments. 

  • Employment situation

For the same reason, when lenders determine your borrowing power, they also consider your type of employment. If you’re self-employed, they’ll likely think of you as higher risk, as it can be more difficult to put a stable number to your income. 

A similar train of thought applies to casual or contract workers, as they can lack job security and benefits like paid leave. So, even if a casual worker and a full-time worker both earn $100,000 in salary, their borrowing capacities would most likely be different. 

  • Your expenses

Besides the cash that’s entering your bank account every month, lenders are also interested in the money that’s going out. They will look at your household spending, including:

  • Electricity, phone and internet bills 
  • Grocery costs
  • Any Afterpay or other buy now pay later debts
  • Media streaming subscriptions 
  • Family expenses. The general rule of thumb is: the more kids you have, the higher your household spending will be and therefore the less you’ll be able to borrow. That’s because every child comes with their own set of expenses, like clothes, school fees and childcare costs. 

With lenders now keeping a close eye on your living expenses, a great way to improve your chances of borrowing more is to cut down on unnecessary purchases and reduce your expenses at least 3-6 months before taking out a home loan

  • Your debt

Got any credit cards, personal loans or car loans under your belt? Lenders will also want to know about those. 

If you’ve got other debts hanging over your head, your borrowing power will be lower, since you’ll be seen as less able to repay your mortgage. That’s why it’s important to minimise other debt before you apply for a home loan. 

Got multiple credit cards or personal loans to pay off? You could use a debt consolidation loan to combine all your debt into one easy-to-manage debt and save on interest costs. 

But if you’ve just got one credit card to pay off and want to dodge high interest while doing so, going with a balance transfer could be a better choice, as most balance transfer deals come with a 0% interest period. 

Top tip: What if you don’t owe anything on your credit card? You might be surprised to hear that that’s still seen as potential debt in the eyes of the lender, because you could rack up a debt as high as your credit limit whenever you want. So before you borrow, make sure to reduce your available credit by cancelling any cards you aren’t using. 

If I’m earning a $100,000 salary, what home loan is right for me? 

Depending on which home loan you choose, your borrowing power could vary quite a lot. Features like interest only repayments, fixed rate and variable rates can all influence the amount you’re able to borrow, not to mention that each lender has its own eligibility criteria you’ll need to meet. 

So which is the right home loan for you? Well, it really comes down to each person’s unique circumstances, but here’s a rundown of how some of those features could influence your borrowing power: 

  • Fixed rate vs variable rate

With variable rate loans, you could lose some of your borrowing power. That’s because when lenders assess your home loan application, they generally add a minimum 1.5% buffer on top of the standard variable interest rate. So instead of the advertised rate of, say, 4%, your lender may use an assessment rate of 5.5% to work out your ability to pay off the loan. 

This buffer helps to offset some of the risks associated with interest rates rising, as higher rates in the market would cause your variable loan repayments to increase too.

By contrast, fixed rate loans tend to have a lower or no assessment rate, so choosing one of those loans could help you to borrow more. 

Fixed rate loans also make budgeting down the track a lot easier, since they guarantee you one interest rate over 3 or 5 years. So if you’re currently not in the financial position to handle sudden rate fluctuations, a fixed rate loan might be the better choice for you. 

But on the flipside, fixed rate loans usually don’t allow borrowers to make additional repayments, unless you pay a fee. 

When would this limit become frustrating? Say, your company gives you pay rise, so you start earning $120,000 instead of $100,000 a year. With more money in your bank account, you’re keen to dedicate a larger portion of your new salary to your mortgage so you can pay off your loan faster and save on interest. However, because you chose a fixed rate loan, you end up having to stick with your initial repayment amount, or else, you’d be hit with extra fees.

For this reason, variable rate loans are a great option if you want to leave all of your repayment options open. They generally come with a range of flexible features, including: 

  • Free extra repayments
  • Unlimited redraws on any additional repayments
  • An offset account
  • Principal + interest vs interest only

If you choose an interest only loan, keep in mind you may not be able to borrow as much as you could on a typical principal and interest loan.

That’s because interest only loans can carry more risks than principal and interest loans. While you won’t need to pay down principal initially and the repayments could be lower during the interest-only period, you will have to make a balloon payment at the end of the loan period. So the more you borrow, the more likely you are to not be able to pay it back and default. 

And because you would have more outstanding debt over the term of an interest only loan, you could also expect higher interest costs and a bigger dent in your budget. 

  • Length of loan term

When choosing your loan term, the rule of thumb is: borrowing power shrinks when you have a shorter loan term, since monthly repayments become higher. 

So extending your loan term could actually boost your borrowing capacity, although the downside of this is you’ll end up paying more interest over the life of the loan. 

More FAQS 

How much deposit should I save up for a home loan? 

While there are loans available with all kinds of deposits the magic number is 20% of the property’s value, if you want to avoid Lenders Mortgage Insurance (LMI). So if you’re looking to buy a property for $500,000, that means you’ll need to have a deposit of $100,000. 

Of course, saving up $100,000 is no easy feat - if you’re earning $100,000 a year, that’s one year’s worth of salary before tax! 

These days, the minimum deposit you need for a home loan is 5%, as the maximum you can borrow is 95% of the property value. But keep in mind that if you’ve saved up less than 20% of deposit, you will have to pay LMI, which could eat up thousands of dollars out of your budget. 

For instance, Sam is a first home buyer who wants to buy a $500,000 house. If he has only saved up a 5% deposit of $25,000, then he could expect to pay $15,960 in LMI!** That would be a huge blow to his bank account. 

How do I get approved for a home loan? 

To take out a home loan, you’ll need to be over 18 years old and an Australian citizen or resident. But bear in mind the best rates are generally reserved for the best quality borrowers. Quality is determined by how much deposit you have, your credit history, your income, your expenses, your savings track record, and any other financial commitments you have. Lenders are interested in how responsible you’ve been with your money, so they want to make sure you’ll be able to pay off your mortgage. 

Once you’ve figured out your borrowing capacity and made sure you’re financially prepared to take out a home loan, then it’s a matter of sorting out all of your paperwork. Each lender will look for slightly different requirements, but in general, you’ll be asked to provide: 

  • 100 points of ID
  • Proof of income 
  • Details of your assets and liabilities
