Both are loans — but choosing the wrong one for your situation can cost you significantly more than necessary. Here is a clear breakdown of when each option makes financial sense, with real numbers.
The core difference
A mortgage is a secured loan — the property itself is collateral. Because the lender has security, mortgage rates are lower and terms are longer (typically 15–30 years).
A personal loan is unsecured — no collateral required. Because the lender takes more risk, rates are higher and terms are shorter (typically 1–7 years).
When to use a mortgage
A mortgage is the right choice when:
- You are purchasing a property
- You need to borrow a large amount (typically above $50,000)
- You can commit to a long repayment term
- You want the lowest possible monthly payment

When to use a personal loan
A personal loan makes more sense when:
- You need funds quickly (personal loans typically disburse in days vs weeks for mortgages)
- The amount is relatively small ($5,000–$50,000)
- You want no property involved as collateral
- You can afford higher monthly payments over a shorter term

Real cost comparison — $30,000 over 5 years
Personal loan at 12%:
- Monthly payment: ~$667
- Total interest: ~$10,020
- Total repaid: ~$40,020
Mortgage (portion only) at 6.5%:
- Monthly payment: ~$585
- Total interest: ~$5,100
- Total repaid: ~$35,100
The mortgage saves roughly $5,000 in interest over 5 years — but requires property as security and involves significantly more paperwork and time.

Frequently asked questions
Can I use a personal loan as a deposit on a house? Most mortgage lenders will not accept a personal loan as a deposit source, as it increases your total debt load. Some lenders specifically ask whether your deposit is borrowed.
Is it ever worth getting a personal loan instead of remortgaging? For small amounts (under $20,000) and short terms, a personal loan can be faster and simpler than remortgaging. Compare the total interest cost, not just the monthly payment.
What happens if I cannot repay a mortgage? The lender can repossess the property. This is the core risk of secured borrowing — always ensure the repayments are manageable before committing.
