Borrowing Power Guide
The Property Plug
Understand Your Borrowing Power
Estimate what you may be able to borrow, understand lending factors, and plan your next move with confidence.
How much can you borrow? This is the fundamental question that shapes your entire home building journey. Yet many buyers never properly understand their borrowing power before they start looking at land or builders.
Guessing at your borrowing capacity is risky. Overestimate and you will fall in love with properties you cannot actually afford. Underestimate and you might leave money on the table. At The Property Plug, we help you understand your genuine borrowing power so you can set a realistic budget and make confident decisions.
Factors That Affect Your Borrowing Power
Income
Lenders assess what you earn and whether that income is stable and verifiable. Regular employment income is easiest to assess. FIFO workers, contractors, self-employed professionals and recent migrants often face more scrutiny but can still borrow -- they just need stronger documentation.
Existing Debt
Lenders look at your total debt-to-income ratio. The more debt you already carry, the less you can borrow. High credit card balances, car loans, and personal loans all reduce your borrowing capacity. Paying down existing debt before applying for a mortgage improves your position significantly.
Deposit Size
A larger deposit means a smaller loan amount and lower risk to the lender. Deposits of 20% or more usually attract better rates and avoid mortgage insurance. Smaller deposits (5-10%) are possible but attract mortgage insurance and stricter lending criteria.
Employment Stability
Lenders want to see consistent employment history. Recent job changes, gaps in employment or frequent job changes raise concerns. Two or more years in your current role strengthens your position.
Living Expenses
Lenders assess your living costs. High rent, large family expenses or other obligations reduce your borrowing capacity. Living frugally and minimising unnecessary expenses improves your position.
Property Type and Location
Some property types and locations are riskier to lenders. Regional properties may attract lower lending ratios than metropolitan properties. Unit apartments may face stricter lending than houses.
Credit History
Your credit score reflects your track record of managing debt. Good credit history strengthens your application. Poor credit history or recent defaults make borrowing harder, though not impossible -- alternative lenders may still work with you.
How Lenders Calculate Borrowing Power
Lenders typically use these approaches:
Serviceability Assessment
Lenders calculate what repayment you can afford based on your income and expenses. They apply a "serviceability buffer" -- typically 2-3% above the actual interest rate -- to ensure you can still repay if rates rise.
Loan-to-Value Ratio
Lenders cap how much they will lend based on property value. With a 20% deposit you get a 80% loan-to-value ratio. With a 10% deposit you get a 90% ratio. With a 5% deposit you get a 95% ratio.
Debt-to-Income Ratio
Lenders assess your total debt against income. Typical caps are 40-50% of gross income going to loan repayments. Higher debt-to-income ratios mean lower borrowing capacity.
Estimating Your Borrowing Power
Assess Your Income
Document your income from all sources over the last 2+ years. If you have changed jobs recently, both employers may be assessed. FIFO workers, contractors and self-employed professionals should gather 2+ years of tax returns or financial statements.
Calculate Your Existing Debt
List all outstanding debts: mortgages, car loans, personal loans, credit card balances. Calculate monthly repayments. Lenders will add your potential mortgage to these existing repayments.
Estimate Your Living Expenses
List essential monthly expenses: rent, utilities, groceries, insurance, childcare, transport. Be realistic about what you spend. Lenders will assess whether you can afford a mortgage alongside these expenses.
Determine Your Deposit
How much can you realistically save or access? Your deposit determines your loan amount and loan-to-value ratio.
Check Your Credit Score
Request your credit report and score. Address any errors or issues. If your score is poor, work on improving it before applying for a mortgage.
Speak with Lenders
Different lenders have different criteria. A bank might decline you while an alternative lender approves you. We connect you with lenders appropriate for your situation.
