Sydney Apartment Rent vs Buy: The Numbers Explained
Every rent versus buy calculator answers the question you already answered when you typed in a growth rate. Here is the arithmetic that proves it, the one number that swamps everything people actually argue about, and why the pessimistic row in most of these tables is not pessimistic enough.
The short answer
There is no general answer to rent versus buy, and anyone offering one has substituted their assumptions for yours. The outcome of any comparison is driven overwhelmingly by the capital growth rate assumed, which nobody can know in advance. In the illustrative scenario below, the entire difference in cash outlay between owning and renting over a decade is around $143,000, while changing only the growth assumption across a plausible range moves the 10 year position by around $843,000. The assumption beats the arithmetic by nearly 6 to 1. And the downside is not hypothetical: the ABS reported that the mean price of residential dwellings in New South Wales fell in the June quarter 2026. The honest conclusion is not a number. It is that the decision rests on things the spreadsheet cannot settle, and you are better served knowing which assumption is carrying the weight than by a calculator that hides it.
Every calculator is circular
Open any rent versus buy calculator. It will ask you for an expected capital growth rate, probably an expected investment return, often an expected rent increase.
Then it will do some arithmetic and tell you the answer.
The answer is your assumption. You supplied the only inputs that materially matter, and the calculator handed them back with decimal places attached and the authority of a chart. It did not discover anything. It restated your prior in a format that feels like a finding.
A calculator that asks you for the growth rate is not answering the question. It is asking you to answer it, then congratulating you on your reasoning.
This is not an argument against doing the arithmetic. It is an argument for doing it the other way around: rather than picking one assumption and generating one answer, run the same scenario across a range of assumptions and see how much the answer moves. If it barely moves, the arithmetic is telling you something. If it swings wildly, the arithmetic is telling you that it cannot settle this and something else has to.
That is what the rest of this page does. It swings wildly.
What each side actually costs
Before any numbers, the accounting has to be honest in both directions, because most rent versus buy content is not.
What buyers underestimate
The mortgage repayment is not the cost of owning. It is one component. On a Sydney apartment the others include:
- Strata levies. Usually the largest recurring cost after the mortgage. They cover administration and the capital works fund, and they can be supplemented by special levies for major building work.
- Council rates and water charges. Recurring, and rising.
- Insurance. Building insurance is typically covered by the strata scheme. Contents is not.
- Maintenance inside your own walls. Appliances, fittings, anything the scheme does not cover.
- Transaction costs at both ends. Transfer duty where it applies, legal and conveyancing fees and inspections on the way in; agent commission and legal fees on the way out. These are incurred in full regardless of how long you hold.
None of those build equity. All of them recur. This is the single biggest reason a mortgage repayment cannot be compared directly against rent.
What renters underestimate
The other side has costs too, and they are less visible because they are not invoiced.
- No forced saving. A mortgage repayment includes principal, which is compulsory saving disguised as an expense. Renting requires you to replicate that voluntarily, and most people do not.
- Exposure to rent movement. Your housing cost is repriced periodically by someone else.
- Security of tenure. Moving is expensive, disruptive, and not always your choice.
- No control over the asset. You cannot renovate, and improvements you do make accrue to someone else.
The framing that keeps both sides honest: owning converts an ongoing expense into a mix of expense and forced saving, at the price of large one-off costs, illiquidity and exposure to a single asset. Renting keeps flexibility and liquidity at the price of no accumulation and no control. Neither is free. Neither is obviously better. Anyone who tells you one of them is throwing money away has not counted the other one properly.
The illustration, and its assumptions
Now the arithmetic. Read the assumptions carefully, because they are the entire point.
These are illustrative round numbers, not market data. They were chosen to be easy to follow, not to describe the market. Substitute your own. The conclusion of this page does not depend on the specific figures and would hold at almost any plausible set.
The scenario, over a 10 year holding period:
- Apartment price: $800,000
- Deposit: $160,000, being 20 per cent
- Loan: $640,000 over 30 years at 6.00 per cent per annum, held constant throughout
- Ongoing ownership costs: $10,000 per year covering strata, council rates, insurance, water and maintenance, held flat
- Rent alternative: $700 per week, increasing 3 per cent per year
Over the decade, the owner’s mortgage repayment is about $3,837 per month. Ten years of repayments comes to roughly $460,000, and the loan balance falls to about $535,600. Adding $100,000 of ownership costs, the total cash outlay is roughly $560,000, excluding the deposit.
The renter, starting at $700 a week and rising 3 per cent annually, pays roughly $417,000 over the same 10 years.
So on pure cash out the door, ownership costs about $143,000 more across the decade. That is the number rent versus buy arguments usually revolve around.
Now the part that decides everything.
| Capital growth assumed | Property value at year 10 | Loan balance | Equity |
|---|---|---|---|
| Minus 3% per year | $589,900 | $535,600 | $54,400 |
| 0% per year | $800,000 | $535,600 | $264,400 |
| 3% per year | $1,075,100 | $535,600 | $539,500 |
| 6% per year | $1,432,700 | $535,600 | $897,100 |
Same buyer. Same loan. Same repayments. Same costs. One assumption changed, and the 10 year position moves by roughly $843,000.
Look at the top row for a moment, because it is the one that does the most work. At minus 3 per cent a year, the buyer has put in a $160,000 deposit, paid about $560,000 across the decade, and holds $54,400 of equity. Nothing went wrong operationally. The repayments were made, the strata was paid, the loan amortised exactly as scheduled. Only the assumption changed.
The finding: the assumption swamps the arithmetic
Put the two numbers side by side.
The difference in cash outlay between owning and renting over 10 years, in this scenario, is about $143,000. That is the territory of the entire public debate: whether rent is dead money, whether strata is too high, whether repayments beat rent.
The difference between the bottom and top growth scenarios is about $843,000. Nearly 6 times larger, produced by a single number nobody can verify in advance.
The variable everybody argues about is worth less than a fifth of the variable nobody can know. That is the whole finding.
Which leads somewhere uncomfortable but useful. If your rent versus buy decision only works at an optimistic growth assumption, you have not done a financial analysis. You have made a bet and dressed it in a spreadsheet. That may still be a reasonable bet. But you should know that is what it is, because a bet you understand is a different thing from a calculation you trust.
Note what the table does not do: it does not say which growth rate is likely. We do not forecast property values, we are not qualified to, and nobody who does it reliably is publishing it on a blog. The rows exist to show sensitivity, not to nominate a winner.
Why the bottom row is not the bottom
Most versions of this table, including the earlier version of this page, start at zero growth and treat that as the conservative case. It is worth being clear that zero is not the conservative case. It is the middle of the downside.
The Australian Bureau of Statistics publishes the mean price of residential dwellings by state each quarter. In its release for the June quarter 2026, published on 8 September 2026, the mean price of residential dwellings in New South Wales was $1,304,900, down from $1,337,600 in the March quarter and $1,328,600 in the December quarter 2025. The total value of residential dwellings in New South Wales fell 2.0 per cent over the quarter. Nationally the mean price fell $8,200 to $1,100,400.
The Reserve Bank made the same observation independently. In its statement of 11 August 2026 the Board noted that momentum in the housing market has shifted, with housing prices falling in some capital cities and new housing loans declining noticeably.
Three things need saying carefully about that, because this page’s whole argument is against overreading data.
- That is a NSW figure covering all residential dwellings. It is not a Sydney figure, and it is not an apartment figure. We are not claiming it describes the property you are looking at.
- Two quarters is not a trend, and we are not forecasting anything from it. Prices move in both directions and have done so repeatedly.
- It is enough to establish one narrow point. A negative row belongs in the table. Negative growth over some periods is an ordinary feature of property markets rather than an exotic scenario, and a sensitivity analysis whose worst case is zero is not testing the downside at all.
That is the whole use of the data here. Not to predict, but to justify the range. If your case still works at the top row, it is robust. If it only works at the bottom two, you have located the assumption doing the work.

We will work out what you could realistically borrow, what the repayment looks like assessed properly, and what the ongoing costs would be on the sort of property you are considering. We will not tell you whether to buy. We will make sure the numbers you decide on are real ones.
What we deliberately did not model
Most rent versus buy analyses include a step we have left out on purpose, and the reason matters.
The standard approach assumes the renter invests the deposit and any monthly cash flow difference, then compares the resulting portfolio against the owner’s equity. It is a reasonable methodology. We have not done it, because doing it requires assuming an investment return, and comparing residential property against other asset classes is financial product advice.
Intellect Finance holds an Australian Credit Licence, not an Australian Financial Services Licence. We are licensed to arrange credit. We are not licensed to advise you on investments or to tell you what returns to expect from anything, and we are not going to imply it by putting a number in a table. If you want that comparison done properly, a licensed financial adviser is the correct person, and the answer will be better for having come from someone qualified to give it.
Which incidentally strengthens the point. If adding a second unknowable assumption is what a full model requires, and one unknowable assumption already produces an $843,000 spread, then a model with 2 of them is not more precise. It is less. Every additional forecast input widens the range of defensible answers rather than narrowing it.
Other things excluded from the illustration, for transparency: selling costs at year 10, any change in interest rates over the decade, offset balances or extra repayments, vacancy or moving costs on the rental side, tax treatment of any kind, and special levies. Several of those would move the result. None of them would move it by anything approaching $843,000.
Why apartments are their own question
The analysis above applies to housing generally. Apartments add specifics worth separating out, because a great deal of rent versus buy commentary quietly assumes a house.
The strata layer. Levies are a genuine, ongoing, non-equity-building cost that houses do not carry in the same form. They also carry a tail risk that houses do not: a special levy for major building work is a decision made collectively by the owners corporation, not by you. Reading the strata records before buying is the single most useful piece of due diligence available on an apartment purchase, and it is a question for your solicitor or conveyancer.
Lender treatment differs. Apartments are not assessed identically to houses. Lender security policy can treat high-density buildings, very small apartments and particular locations differently, including through maximum loan-to-value ratios. That is a real constraint on what you can borrow and it varies by lender, which we cover in do I need a local mortgage broker.
The growth question is separate, and we are not answering it. Whether apartments and houses behave the same way over time is a genuine research question, and it is exactly the kind of question this page argues you should not accept a confident answer to from someone selling you something. The ABS figures cited above cover all residential dwellings and do not separate the two. If your case depends on apartment growth specifically, that is an assumption worth naming out loud rather than importing from housing-wide commentary.
The variables that legitimately dominate
Given that the arithmetic cannot settle it, what should?
Mostly things that do not appear in any calculator, and it is not a cop-out to say so. When the financial case is genuinely ambiguous across a wide range of assumptions, the non-financial factors are not tiebreakers. They are the decision.
- How long you expect to stay. The most important input in the whole exercise, and the one you have the best information about. Transaction costs are incurred in full regardless of holding period, so short holds are where ownership is most exposed.
- How much security of tenure is worth to you. For some households the answer is a great deal. For others it is close to nothing. Both are legitimate and neither is a spreadsheet output.
- Whether you would actually save the difference. Be honest. The forced-saving effect of principal repayment is real, and it is the strongest financial argument for ownership that does not require a growth forecast.
- Concentration. Buying puts a very large proportion of most households’ net worth into one asset in one city. That is a risk position, not just a purchase.
- What flexibility is worth. Career, family, relationships. Owning reduces optionality, sometimes at exactly the wrong moment.
What to actually do with this
- Rebuild the scenario with your numbers. Your price, your deposit, your actual rent, the real strata on the buildings you are looking at. Ask for the strata figures before you fall in love with anything.
- Run it at 4 growth rates, not one. Negative, zero, modest, optimistic. If the decision only works at the top one, you have found the assumption doing the work.
- Find out what you can actually borrow first. Serviceability is assessed with a buffer of 3 percentage points above the actual rate, which APRA confirmed in November 2025 remains in place. Our guide to 5 per cent deposit home loans covers why capacity, not deposit, is usually the real limit.
- Check whether duty applies to you. First home buyers in New South Wales may receive a full exemption or a concession depending on the property value, under thresholds published by Revenue NSW. Eligibility conditions apply, and it is a material line item.
- Answer the stay question honestly before the money question. It has more explanatory power than anything in the table above.

Frequently Asked
Rent vs Buy Questions
The questions people ask once they stop expecting a calculator to decide for them.
Is it better to rent or buy an apartment in Sydney in 2026?
There is no general answer, and anyone giving you one has substituted their assumptions for yours. The result of any rent versus buy comparison is driven overwhelmingly by the capital growth rate you assume, which nobody can know in advance. In the illustrative scenario on this page, changing that single assumption across a plausible range moves the 10 year outcome by nearly 6 times the entire difference in cash outlay between owning and renting. The honest position is that the arithmetic cannot settle the question, so the decision comes down to which assumptions you are willing to defend and to factors that are not financial at all.
Why do rent vs buy calculators give such different answers?
Because they are not calculating the answer, they are restating the assumptions you fed them. The capital growth rate, and often an assumed investment return, dominate the result. Two calculators given different growth inputs will disagree wildly on identical arithmetic. This is why running one scenario is close to useless and running several is genuinely informative: the spread between them tells you how much of the conclusion is arithmetic and how much is your own prior.
What is the biggest variable in a rent vs buy comparison?
Capital growth, by a very large margin, and it is the one nobody can know in advance. In the scenario on this page the entire difference in cash outlay between renting and owning across a decade is about $143,000, while the range produced by the growth assumption alone is about $843,000. Everything the public debate argues about is worth less than a fifth of the thing nobody can verify.
Should a rent vs buy analysis include falling prices?
Yes, and most do not. A sensitivity analysis whose worst case is zero growth is not testing the downside. Falling prices are an ordinary feature of property markets rather than an exotic scenario: the ABS reported that the mean price of residential dwellings in New South Wales fell in the June quarter 2026, and the Reserve Bank noted in August 2026 that housing prices were falling in some capital cities. That is not a forecast and 2 quarters is not a trend, but it is reason enough that a negative row belongs in the table.
What ongoing costs do apartment buyers underestimate?
Strata levies first, since they are usually the largest recurring cost after the mortgage and cover administration and the capital works fund. Then council rates, water, contents insurance and maintenance inside your own walls. Special levies for major building work are the tail risk, because they are decided collectively by the owners corporation rather than by you. None of these costs build equity, and all of them recur, which is why a mortgage repayment cannot be compared directly against rent.
Why does this analysis not model the renter investing the difference?
Because doing so requires assuming an investment return and comparing residential property against other asset classes, which is financial product advice. Intellect Finance holds an Australian Credit Licence, not an Australian Financial Services Licence, so we are not licensed to do it and will not imply otherwise by putting a number in a table. A licensed financial adviser is the right person for that comparison. It also happens to reinforce the point: adding a second unknowable input widens the range of defensible answers rather than narrowing it.
Does buying always beat renting in the long run?
No, and the claim only holds if you assume the thing being argued. Long holding periods do reduce the impact of transaction costs and give the forced-saving effect of principal repayment more time to work, both of which favour ownership. But the outcome still depends on growth over the period you actually hold, and in the illustration on this page a decade of negative growth leaves the buyer with $54,400 of equity after a $160,000 deposit and about $560,000 of outlay. Time helps. It does not guarantee.
How long do you need to own before it makes sense financially?
There is no fixed number, and anyone quoting one is assuming a growth rate to produce it. What can be said without assuming anything is that transaction costs are incurred in full regardless of how long you hold, so short holding periods are where ownership is most exposed. Your expected length of stay is also the input you have the best information about, which makes it the most reliable thing in the whole exercise.
What should I actually do with this analysis?
Rebuild it with your figures: your price, your deposit, your actual rent, and the real strata on the buildings you are considering. Run it at 4 growth rates including a negative one. Find out what you can genuinely borrow first, since capacity is often the binding constraint and is assessed at 3 percentage points above the actual rate. Check whether duty relief applies. Then answer the length-of-stay question honestly, because it carries more weight than anything in the table.
The honest bottom line
The rent versus buy question is posed as arithmetic and answered as ideology. One side says rent is dead money. The other says the buyers are over-leveraged. Both are describing their assumptions and calling it analysis.
What the numbers actually show, at least in the illustration above, is that the thing everybody argues about is worth about $143,000 across a decade, and the thing nobody can know is worth about $843,000. When the unknowable input outweighs the arguable one by nearly 6 to 1, the arithmetic has told you something genuinely useful: it cannot settle this, and you should stop expecting it to.
So do the sums with your own figures, run them at more than one growth rate including a negative one, and notice which assumption is carrying the decision. Then make the call on the things you actually have information about, which are how long you intend to stay, whether you would really save the difference, and how much a stable address is worth to you. Those are not lesser reasons because they are not numbers. On this question they are the better ones, because they are the only inputs you can actually verify.

The scenario figures are illustrative, not market data and not a projection. Every figure in the scenario and the sensitivity table is a hypothetical round number chosen for arithmetic clarity. They are not Sydney median prices, median rents, yields or strata levies, and they are not intended to describe any actual market. The arithmetic assumes an $800,000 purchase, a $160,000 deposit, a $640,000 loan over 30 years at 6.00 per cent per annum held constant, ownership costs of $10,000 per year held flat, and rent of $700 per week rising 3 per cent per year. No interest rate stated is an offer or an available rate. Real outcomes will differ.
About the ABS and RBA material. The ABS figures cited are published estimates of the mean price of residential dwellings by state for the June quarter 2026, released 8 September 2026, and all current-quarter estimates are preliminary and subject to revision. They cover all residential dwellings, do not separate houses from apartments, and are a New South Wales figure rather than a Sydney figure. They are cited to establish that periods of negative movement occur, not to describe any particular property, suburb or dwelling type. The RBA observation is quoted from its published statement of 11 August 2026. Two quarters of movement is not a trend and nothing here should be read as a forecast.
No forecasts. The growth scenarios shown are a sensitivity range, not predictions, and no view is expressed or implied about which is more likely. Intellect Finance does not forecast property values or interest rates, and nothing on this page should be read as doing so. Past performance of any market is not an indicator of future performance.
Excluded from the illustration. Selling costs, changes in interest rates over the period, offset balances and extra repayments, vacancy and moving costs, special strata levies, and tax treatment of any kind. Several of these would change the result.
Strata and property due diligence. Strata records, capital works funds, special levies, by-laws and building defects are matters for your solicitor or conveyancer and appropriately qualified inspectors, and should be investigated before any purchase.
Regulatory settings. The 3 percentage point serviceability buffer was confirmed in APRA’s information paper of 27 November 2025. It is a prudential expectation placed on lenders, creates no entitlement for any borrower, and changes over time. New South Wales transfer duty thresholds for first home buyers are published by Revenue NSW and eligibility conditions apply. Settings are stated as reviewed on 10 September 2026 and are subject to change.
Lender policies vary and change. Borrowing capacity, deposit requirements, security policy on apartments and maximum loan-to-value ratios differ between lenders and are subject to each lender’s own assessment and to change without notice. This page names no lenders. No broker can guarantee loan approval, a particular interest rate, or a timeframe.
Best Interests Duty. A home loan for a property you will live in is regulated consumer credit under the National Consumer Credit Protection Act 2009, and Best Interests Duty applies to the credit assistance we provide. That duty relates to credit assistance and does not extend to investment advice, which we are not licensed to give.
What we charge you. Nothing, on any loan type. No arrangement fee for residential, commercial, corporate, asset, SMSF or personal lending, no fee for complex or specialist lending, and no clawback recovery fee if a loan is discharged early. Lenders pay us a commission on settlement, disclosed to you in writing in our Credit Guide before we provide credit assistance.
