Buy a Home vs Renting: Long-Term Comparison
Compare the financial outcomes of buying versus renting based on your timeline, location, and lifestyle preferences. Run scenarios to guide your housing decision.
Buy or Rent: The Real Question
The "should I buy or rent?" decision is less about math and more about life circumstances. However, understanding the financial outcomes of each path is essential before making a choice.
The answer depends on:
- How long you'll stay: Buying works best for 7+ year horizons. Under 5 years, transaction costs favor renting.
- Your local market: In cities with high rental yields (e.g., some regional areas), renting and investing elsewhere may outperform buying.
- Career mobility: If you change jobs/cities every 3–4 years, renting offers flexibility that ownership doesn't.
- Deposit availability: A 20% deposit ($180k on a $900k home) changes the comparison substantially vs. a 5% deposit ($45k) with mortgage insurance.
- Lifestyle preferences: Some people value ownership and stability; others value flexibility. Both are valid.
Entry Costs (Upfront)
- Mortgage insurance: 0.5–3% if deposit < 20% (e.g., $14k on a $900k home with 5% deposit)
- Legal fees, conveyancing, inspections: $2–5k
- First home buyer grants: Up to $15k in some states (NSW, VIC) if eligible
Ongoing Costs (Annual)
Exit Costs (Sale)
- Agent commission: 1.5–3% of sale price (~$13,500–27,000 on $900k)
- Legal & settlement fees: $1,000–2,000
- Total: ~$15,000–30,000
Break-even horizon: You typically need to own for 5–7 years for capital growth and the rent-equivalent benefit to exceed transaction costs.
Costs of Renting
Entry Costs
- Bond: Usually 4 weeks' rent
- Rental application/admin: $100–300
- Total entry: ~$2,000–4,000
Ongoing Costs (Annual)
- Rent: On a $900k home in a typical Australian suburb, expect $15,000–18,000 annually ($290–350/week)
- Utilities: Typically tenant's cost, $200–400/month
- Renter's insurance: $200–400/year
- Total annual cost: $18,000–22,000
Special Case: Rent Growth
Rent grows at inflation + demand. Over 10 years, expect 2–3.5% annual growth. That "$350/week" becomes ~$460/week in 10 years. This erodes the renting advantage over long periods.

Buy vs Rent Model
Three Real Scenarios
Scenario A: The Short-Term Renter (3–5 years)
- Situation: First job, might relocate for career, want flexibility
- Rent path: $350/week = $18,200/year; 5 years = ~$91,000 total
- Buy path: $900,000 home, 10% deposit ($90k), $810k loan at 6% over 30 years. Annual cost: ~$60k (mortgage + rates + insurance + maintenance)
- 5-year comparison:
- Buy: Paid $60k/year × 5 = $300k; home has grown to ~$1.05m; equity ~$240k (initial + principal repayment + appreciation). Transaction cost to sell: ~$30k net less.
- Rent: Paid $91k; has $90k deposit still in savings, could invest it. 5-year wealth: Renting = rent paid ($91k) vs. buying net cost time $200k. Renting wins.
- Outcome: Renting is cheaper for short horizons.
Scenario B: The 10-Year Owner (First-Time Buyer, 30s)
- Situation: Stable job, partnered, Want to build equity and lock housing cost
- Rent path: $350/week growing at 3%/year = $19k year 1, but growing. Year 10 weekly rent ~$470/week. Total 10-year rent: ~$215k
- Buy path: Same $900k home, 20% deposit ($180k), $720k loan at 6%. Annual cost: ~$55k (mortgage + rates + insurance). 10-year total paid: $550k. Home value at 3.5% growth: ~$1.28m. Equity: ~$560k (deposit + principal + appreciation). Less sale cost: ~$530k net position.
- 10-year comparison:
- Rent: Net cost $215k (but housing is no longer "paid off"—rent continues)
- Buy: Net cost $550k paid, but own $1.28m asset with $560k equity
- Wealth: Buy is ahead by ~$345k ($560k equity - $215k rent savings)
- Outcome: Buying wins at 10 years, especially if you stay longer.
Scenario C: The 20-Year Wealth Builder
- Situation: Early 30s, stable income, plan to stay settled, focus on building wealth
- Rent path: $350/week in year 1, growing 3%/year. Year 20 rent: ~$595/week. Total 20-year rent: ~$520k. Renter ends with no housing asset; rent continues rising.
- Buy path: $900k home, 20% deposit ($180k), $720k loan. With standard repayment, loan becomes nearly debt-free by year 25. Annual cost $55k year 1, dropping materially after year 15. Home value at 3.5% growth: ~$1.814m. Equity position: ~$1.8m (largely debt-free). Housing is "paid for."
- 20-year comparison:
- Rent: $520k paid, no asset
- Buy: $1.1m paid, own $1.81m property (debt-free/minimal debt)
- Wealth gap: Buy is ahead by ~$700k in equity, plus no ongoing rent burden
- Outcome: Buying decisively wins for 20+ year horizons.
Non-Financial Factors That Matter
Buying Pros
- Build equity; housing cost eventually becomes negligible (principal paid off)
- Pride of ownership; ability to renovate/customize
- Stability; kids can grow up in same suburb/school
- Hedge against rent inflation
Buying Cons
- Illiquid; takes months to sell if you need to move quickly
- Maintenance surprises and upkeep burden
- Rates, insurance, and tax creep higher over time
- Career flexibility reduced (harder to relocate for a new job)
Renting Pros
- Flexibility; easy to move for work or lifestyle changes
- No maintenance risk or surprise bills
- Less capital commitment; can invest deposit elsewhere
- No transaction costs (entry or exit)
Renting Cons
- No equity building; rent is a cost, not investment
- Rent increases over time; housing cost never "finishes"
- Less stability; landlord can ask you to leave (though laws protect tenants)
- Psychological: always subject to someone else's rules and property decisions
Mint Takeaway
Buy if your timeline is 10+ years and you're stable in your location. Rent if you're mobile, enjoy flexibility, or have a horizon under 5 years. Between 5–10 years, it's a toss-up based on your assumptions, deposit size, and rent growth in your area. Run your own numbers with your deposit, local rent, and expected property growth. The math changes significantly depending on where you live and what you can afford to put down.
