How Much Can I Borrow on a $100k Salary? Plus Answers to 7 Other Common Home Loan Questions

How Much Can I Borrow on a $100k Salary?

One of the most common questions we hear is, "How much can I borrow if I earn $100,000 per year?"

The answer depends on more than just your income. Lenders assess a range of factors including your existing debts, living expenses, credit card limits, dependants, HECS debt, and overall financial position.

As a general guide, someone earning $100,000 annually may be able to borrow between $450,000 and $650,000, depending on their circumstances. For example, a borrower with no dependants, minimal debts, and strong savings may be able to borrow significantly more than someone with multiple financial commitments.

The best way to determine your borrowing capacity is through a personalised assessment, as lender policies can vary considerably.

 

Can I Buy a Home With a 5% Deposit?

Yes, in many cases you can.

Several lenders allow eligible borrowers to purchase a property with as little as a 5% deposit, making home ownership more accessible for first-home buyers and those looking to enter the market sooner.

Depending on your eligibility, you may also qualify for government assistance schemes designed to reduce or eliminate the cost of Lenders Mortgage Insurance (LMI).

It's important to remember that your deposit isn't the only upfront cost. You may also need to budget for:

  • Stamp duty (where applicable)

  • Conveyancing and legal fees

  • Building and pest inspections

  • Government registration costs

A finance broker can help you understand the total funds required before you start your property search.

 

How Does HECS Affect Borrowing Capacity?

A HECS/HELP debt won't negatively impact your credit score, but it can affect how much you can borrow.

This is because compulsory HECS repayments are deducted from your income once you earn above the applicable threshold. Lenders take these repayments into account when assessing your ability to service a home loan.

As a result, borrowers with a HECS debt may have a lower borrowing capacity compared to someone earning the same income without the debt.

The impact varies depending on your income level and lender assessment policies.

 

Should I Refinance My Mortgage?

Refinancing can be one of the most effective ways to improve your financial position, but it isn't always the right solution for everyone.

You may benefit from refinancing if you want to:

  • Secure a lower interest rate

  • Reduce your repayments

  • Access equity for renovations or investments

  • Consolidate debts

  • Obtain better loan features such as an offset account

Before refinancing, it's important to consider any discharge fees, application costs, or break fees that may apply. The key question is whether the long-term savings and benefits outweigh the costs of switching lenders.

Many homeowners are surprised to learn how much they could save by reviewing their home loan regularly.

 

How Much Equity Can I Access?

Equity is the difference between your property's current value and the amount you still owe on your mortgage.

In most cases, lenders will allow you to borrow up to 80% of your property's value without paying Lenders Mortgage Insurance.

For example:

  • Property value: $800,000

  • Existing loan: $400,000

  • Maximum lending at 80%: $640,000

Potential usable equity: $240,000

Accessible equity can be used for a range of purposes, including renovations, debt consolidation, investment property purchases, or wealth creation strategies.

A property valuation and lending assessment will determine exactly how much equity is available to you.

 

How Does an Investment Loan Work?

An investment loan is specifically designed to help borrowers purchase a property that generates rental income.

When assessing an investment application, lenders typically consider:

  • Your personal income

  • Existing debts and commitments

  • Rental income from the proposed property

  • The property's location and security value

Investment loans often have slightly different lending policies and pricing compared to owner-occupied loans.

Investors should also seek professional tax advice, as there may be tax implications and benefits associated with owning an investment property.

 

Should Investment Loans Be Interest-Only?

Interest-only lending can be a useful strategy for certain investors, particularly those focused on maximising cash flow or building a larger property portfolio.

During the interest-only period, repayments are lower because you're only paying interest on the loan balance rather than repaying the principal.

Potential benefits include:

  • Improved cash flow

  • Greater flexibility

  • Potential tax advantages (seek professional advice)

However, interest-only lending isn't suitable for everyone. Once the interest-only term expires, the loan converts to principal and interest repayments, which can result in a significant increase in monthly repayments.

Before choosing this structure, it's important to ensure it aligns with your long-term financial goals.

 

How Does Construction Finance Work?

A construction loan differs from a standard home loan because the funds are released progressively as construction progresses.

Rather than receiving the full loan amount upfront, the lender releases funds in stages, typically including:

  1. Deposit

  2. Slab stage

  3. Frame stage

  4. Lock-up stage

  5. Fixing stage

  6. Completion stage

During construction, you'll generally only pay interest on the amount that has been drawn down, helping keep repayments lower while the build is underway.

Once construction is complete, the loan typically converts to a standard home loan and normal repayment arrangements commence.

Construction finance can be more complex than a standard property purchase, so obtaining guidance early in the process can help avoid delays and unexpected issues.
