Renting instead of buying: the arithmetic nobody shows you

Why the question is hard to ask here

Around nine in ten resident households in Singapore own the home they live in — among the highest rates anywhere. That is a policy achievement, and for most households it has worked. It also means the decision to buy is usually inherited rather than made: it is what one does after marriage, and the only question people feel entitled to ask is when, not whether.

A visible minority now asks whether. They are not, in the main, people who cannot afford to buy — some are higher earners in their twenties to forties with the deposit sitting ready, choosing long-term rentals, serviced apartments or co-living because they want the flexibility more than the asset. Whether that is wise depends entirely on numbers that are specific to them, and the numbers are almost never laid out side by side.

This guide lays them out. It does not conclude that renting is better, because for most households in this country it is not. It concludes that the comparison is winnable either way and worth actually doing.

What buying costs beyond the price

The purchase price is the number everyone compares, and it is the smallest part of the comparison. Buyer's Stamp Duty is payable on every purchase, and Additional Buyer's Stamp Duty on top for anyone who already owns residential property or is not a citizen. Legal fees, valuation and the agent's side of the transaction follow. None of that is recoverable — spend it and it is gone, whatever the property later does.

Then the carrying costs, which run for as long as you hold. Interest, which in the early years of a loan is most of what you pay each month. Maintenance or the management fee. Property tax, at the higher rate if the place is not owner-occupied. Repairs, which arrive on their own schedule.

The one that most people leave out entirely is the CPF accrued interest. Money withdrawn from your CPF Ordinary Account for a property has to be returned when you sell, together with the interest it would have earned had it stayed. That is not a penalty — it is your own retirement money being made whole — but it means the cash you walk away with is smaller than the sale price minus the loan, sometimes by a great deal, and a household that has not counted it will be surprised at exactly the wrong moment.

What renting costs beyond the rent

The rent is the obvious cost and it is genuinely dead money in the sense people mean: it buys shelter and nothing else. But the honest accounting also names what the renter is spared — the stamp duty, the interest, the maintenance, the property tax, the repairs, the agent on the way out, and the risk that the specific property they would have bought underperforms the market they read about.

There is a second, larger item on the renter's side, and it is the one that decides most of these comparisons: the deposit is not spent. A household that rents has the downpayment, the duty and the fees still invested somewhere. Whether that helps depends on what it earns and whether the household genuinely invests it rather than spending it, which is a question about behaviour rather than arithmetic, and honest people give different answers about themselves.

What the renter carries instead is insecurity of tenure and no protection from rising rents. A lease ends. Rents move with the market and have moved sharply here within living memory. Owning fixes your housing cost in a way renting cannot, and for a household that intends to stay in one place for decades that stability is worth real money even when the spreadsheet is close.

The break-even, and why it is measured in years

Buying front-loads its costs. The duty, the fees and the early years of interest all land at the start, and equity accumulates slowly at first because the early instalments are mostly interest. Renting has no entry cost and no exit cost.

So the comparison is not a monthly one. It is a question of how long you stay. Below some number of years, the purchase has not yet earned back what it cost to enter and leave, and renting wins on cash even if prices rose. Beyond it, ownership pulls ahead and keeps pulling. That number moves with the duty payable, the interest rate, the rent you would otherwise pay, and what the deposit would have earned — which is why nobody can quote a single figure for it honestly.

This is also the reason the holding-period rules matter to the decision rather than only to the exit. A property you may need to leave inside a few years is a property whose entry costs you may never recover, and Seller's Stamp Duty or an unfinished occupation period can turn an early exit from expensive into impossible.

Where renting genuinely wins

Short or uncertain horizons. If there is a real chance of leaving the country, changing city, or a relationship or job whose shape is not settled, the entry costs may never be recovered and the holding rules can trap you. Flexibility has a price and sometimes it is worth paying.

Wanting to live somewhere you cannot afford to buy. Rental yields on prime property here are modest, which is the same fact seen from the other side: renting an expensive home costs far less than owning it. A household that wants a central address for a few years can rent one for a fraction of what buying it would tie up.

Where the purchase would be at the limit. A household stretching to the maximum a bank will lend, with no buffer, is buying an asset and a fragility at the same time. Renting something comfortable while building a real reserve is a better position than owning something precarious, and the second is not more responsible than the first merely because it involves a title deed.

Where buying still wins, which is most of the time

For a household that will stay put for a decade or more, ownership is usually the stronger position, and the reasons are not only financial. Housing costs stop rising against you. The forced saving of a mortgage builds equity that most people would not have accumulated voluntarily. CPF can be used for a home and cannot be used for rent, which changes the cash comparison substantially for anyone with a healthy Ordinary Account.

Public housing sharpens this further. A subsidised flat is sold below what it would fetch on the open market, and that discount is real value transferred at purchase — an advantage no rental arrangement offers. For an eligible household, the case for buying is usually made before any of the arithmetic above.

The point is not that renting is generally better. It is that the case for buying is strong enough to survive being examined, and a household that has examined it buys with more confidence and less regret than one that never looked.

How to answer it for yourself

Start with what you could borrow, because it bounds everything else. Total debt servicing is capped at 55% of gross monthly income, and a loan for a flat is additionally capped at 30%. Both tests are run at a stress rate — the higher of a statutory floor of 4% and the actual package — not at the rate you will pay, so the amount a bank will lend is smaller than the amount today's rates suggest.

Then be honest about the horizon. Not the horizon you would like to have, but the one your life actually supports. A household that says ten years and means three should read the holding rules before the price list.

And compare the whole cost of each path over that horizon, not the monthly figure. The monthly comparison flatters buying, because it hides the entry costs in the past and the CPF refund in the future. The lifetime comparison is the one that answers the question, and it is arithmetic rather than opinion — which means it can be worked out rather than argued about.

Common questions

Is renting really throwing money away in Singapore?

Rent buys shelter and no equity, which is the sense in which the phrase is true. But mortgage interest, stamp duty, maintenance and property tax are also money that buys no equity, and a renter keeps the deposit invested. Whether the difference favours buying depends on how long you stay, which is why the comparison is measured in years rather than months.

What is CPF accrued interest and why does it matter to this decision?

CPF withdrawn for a property must be returned on sale along with the interest it would have earned in your Ordinary Account. It is your own retirement money being restored rather than a penalty, but it means the cash you receive on a sale is smaller than sale price minus outstanding loan — often materially so, and it is the item most often left out of a rent-versus-buy comparison.

How many years do I need to stay for buying to beat renting?

There is no single honest number. It depends on the stamp duty payable, the interest rate, the rent you would otherwise pay, and what your deposit would have earned elsewhere. What is general is the shape: buying front-loads its costs, so short stays favour renting and long stays favour owning.

Does renting make sense if I can afford to buy?

Sometimes. It fits an uncertain horizon, a wish to live somewhere you could not afford to own, or a purchase that would leave no financial buffer. For a household staying a decade or more in a place it can comfortably afford, buying is usually the stronger position — particularly where a subsidised flat is available, since that discount is value no rental offers.
