How Much Can I Borrow in Brisbane Southside: Your Complete 2026 Guide
Borrowing capacity in Brisbane Southside varies significantly between lenders, often by $50,000 to $100,000 for the same borrower profile. With competitive variable rates from approximately 5.70% p.a. and the RBA cash rate at 4.35%, understanding how different lenders assess your income, existing debts, and living expenses determines whether you can afford that Mount Gravatt or Coopers Plains home or need to look at more affordable options across Runcorn and Brisbane Southside.
The difference is not just the interest rate you qualify for. How lenders calculate your borrowing power, including how they treat rental income, overtime, bonuses, and existing debt commitments, can shift your maximum loan amount substantially.
Mortgage Broker Brisbane Southside helps homeowners and investors compare borrowing capacity across our 50+ lender panel, completely free of charge.
Here's what determines your borrowing power and how to maximise it.
Key takeaways
- Borrowing capacity can differ by $50,000 or more between lenders for the same borrower.
- The APRA serviceability buffer means lenders test your loan at roughly 9% p.a.
- Cancelling unused credit cards before applying can meaningfully increase your loan limit.
What factors determine your borrowing capacity in Brisbane Southside?
Your borrowing capacity depends on four key factors: your gross income, existing debt commitments, living expenses, and the deposit you have available. Lenders use these to calculate whether you can service loan repayments at approximately 9% p.a., around 3% above the actual loan rate as required by the APRA serviceability buffer.
From there, lender policy differences create the variation. Some lenders allow higher debt-to-income ratios for professional borrowers. Others are more generous with overtime and bonus income assessment. That's exactly where broker comparison delivers a stronger outcome.
How much can I borrow with my income?
Most lenders will lend 5 to 6 times your gross annual income, but this varies significantly based on your income type and lender choice. For a $100,000 salary with minimal existing debts, borrowing capacity typically ranges from $500,000 to $600,000 across different lenders.
Self-employed borrowers, casual workers, and those with multiple income sources often see wider variation between lender assessments. A pre-approval assessment across multiple lenders is the clearest way to understand exactly where you stand before making an offer.

What borrowing capacity mistakes do Brisbane Southside buyers make?
The biggest mistake is accepting the first borrowing estimate without comparing lender policies. Using an online calculator or getting a single bank assessment can underestimate your true borrowing power by $50,000 or more, particularly if you have complex income or are self-employed.
Another common error is not understanding how existing debts impact your borrowing capacity. Credit card limits reduce your borrowing power even if you don't use them, and cancelling unused cards before applying can increase your loan amount significantly. Personal loans, car loans, and HECS debt all reduce your borrowing capacity differently across lenders.
How much deposit do you need for different purchase prices?
Your deposit requirement depends on the loan type and schemes you qualify for.
Typical deposit requirements for Brisbane Southside buyers:
- › First Home Guarantee (5% deposit):$50,000 deposit for a $1,000,000 purchase. No LMI with government backing.
- › Standard loan with LMI (5% deposit):$50,000 deposit plus approximately $41,500 LMI for a $1,000,000 purchase.
- › Standard loan (10% deposit):$100,000 deposit plus approximately $19,500 LMI for a $900,000 purchase.
- › No LMI (20% deposit):$200,000 deposit for a $1,000,000 purchase, no additional LMI costs.
- › Professional LMI waiver: doctors, dentists, and other eligible professionals can often borrow up to 90% LVR without LMI at participating lenders.

Frequently Asked Questions
How much can I borrow with a $100,000 salary in Brisbane Southside?
With a $100,000 salary and minimal existing debts, you can typically borrow between $500,000 and $600,000 depending on the lender. Your exact borrowing capacity depends on your existing commitments, living expenses, and which lender assesses your application.
Does my credit score affect how much I can borrow?
Yes, your credit score affects both borrowing capacity and interest rate. A score above 700 typically qualifies for competitive rates, while scores below 600 may reduce borrowing capacity or require specialist lenders with higher rates.
Can I include my partner's income even if they're not on the loan?
Generally no. Lenders only consider income from applicants who will be legally responsible for the loan, so if your partner is not on the application their income typically cannot be included in serviceability calculations.
How do existing debts reduce my borrowing capacity in Brisbane Southside?
Lenders subtract your minimum monthly debt repayments from your available income before calculating borrowing capacity. Credit card limits count as potential debt even if you don't use them, so a $10,000 card limit can reduce borrowing power by approximately $40,000.
Will rental income from an investment property increase my borrowing capacity?
Most lenders include 70 to 80% of rental income in serviceability calculations to account for vacancy periods and maintenance costs. The exact percentage varies by lender, and you'll need a lease agreement or rental assessment as evidence.
Should Brisbane Southside buyers use a mortgage broker or go directly to a bank?
A mortgage broker, every time. Banks can only offer their own products and assessment methods, while brokers compare borrowing capacity across multiple lenders to find the highest loan amount available to you. This comparison often results in significantly higher borrowing power.
How does HECS debt affect borrowing capacity for Brisbane Southside buyers?
HECS debt reduces your borrowing capacity because lenders treat the repayment as an ongoing commitment. For every $10,000 of HECS debt, your borrowing capacity typically reduces by approximately $20,000 to $30,000 depending on your income level.
Your Next Steps
Getting your borrowing capacity right is about more than knowing a number. It's about understanding which lenders assess your specific income and debt situation most favourably. The difference between lender policies can mean access to a higher purchase price or better suburb options across Brisbane Southside.
The right lender for your borrowing capacity depends on your situation, and that's a conversation worth having. Talk to the Evergreen Loan Solutions team or call 0421 152 859, and we'll compare your options across 50+ lenders at no cost to you.
