The rent trap
Adelaide rents have risen sharply - median house rents are at record highs and vacancy rates remain below 1% in most suburbs. Every rent increase makes it harder to save a deposit, creating a cycle that is difficult to break without a clear plan.
But the maths has shifted. With government schemes allowing 5% deposit purchases with no LMI, the barrier to entry is lower than many renters realise. And in many Adelaide suburbs, weekly mortgage repayments are now comparable to weekly rent.
A real comparison
Consider a $550,000 property in Adelaide's middle ring. With a 10% deposit ($55,000), a loan of $495,000 at a typical variable rate over 30 years, your weekly repayment is approximately $720. Illustrative only, not a quote or an offer of credit. Median house rent in comparable suburbs is $500-$600 per week - and rising.
The critical difference: every mortgage repayment reduces your loan balance and builds equity. Every rent payment is gone. Over 5 years, a homeowner on those numbers repays roughly $30,000 of the loan - equity built through repayments alone, on top of the $55,000 deposit and before any price growth.
When renting still makes sense
Renting is the right choice if you need flexibility (likely to move within 2-3 years), if your income is unstable, or if the suburbs you want to live in are priced well above what you can afford to buy. Buying and selling within a short period rarely makes financial sense once you factor in stamp duty, selling costs, and market risk.

Frequently asked questions
Is it cheaper to buy than rent in Adelaide?
In many suburbs yes - particularly with a competitive interest rate and government concessions. A $550,000 property with a 10% deposit at a typical variable rate costs approximately $720 per week in repayments - higher than median rent in some suburbs but comparable in others. The difference is that repayments build equity while rent builds your landlord's.
How much deposit do I need to stop renting?
As little as 5% through the First Home Guarantee - $27,500 on a $550,000 property. Some lenders also accept rental history as evidence of savings capacity, making the transition from renting to owning more accessible than many people realise.
