A couple I met last year were both in their early 50s. Their condominium was almost fully paid, but as they began preparing for retirement, they realised that a large part of their wealth was tied up in the property.
They were asset-rich, but the home did not generate the income they would eventually need after they stopped working.
Their plan was straightforward: sell the condominium, move into a five-room HDB flat and invest the capital released to generate retirement income. This would reduce their housing costs and allow them to enter retirement with more liquidity and less financial pressure.
The numbers worked. The rules did not.
At the time, they would have had to sell the private property first, rent somewhere for 15 months and only then buy an HDB resale flat. That meant two house moves, more than a year of rent and prolonged uncertainty over the price of their replacement home.
Faced with all that disruption, they postponed the decision—and their retirement plan remained largely locked inside their property.
On 28 July 2026, that obstacle disappeared.
The Government removed the 15-month wait-out period for private residential property owners buying non-subsidised HDB resale flats. Private-property owners and former owners of any age can now buy an eligible resale flat of any size without serving the wait.
For households approaching retirement, this is an important change. But not necessarily for the reason most of the coverage suggests.
TL;DR
- Private-property owners can now buy an eligible HDB resale flat before selling their private property, but must dispose of all private residential properties within six months.
- The difference between the two property prices is not your retirement capital. After the mortgage and transaction costs, a headline $1.15M price gain may leave only about $575K for your retirement.
- How you pay for the replacement flat matters. Using CPF preserves cash, while using cash preserves CPF savings and guaranteed interest.
- The waiting risk has become execution risk. Buying first is easy, but financing and the six-month selling deadline must be carefully managed.
- The rule change gives you flexibility, not a retirement plan. Right-sizing works only if the capital released is enough to improve your retirement income and financial resilience.
Why the 15-month rule existed
The rule was introduced in September 2022, during an unusual period for Singapore’s housing market.
COVID-19 had delayed the construction of new BTO flats. At the same time, low interest rates and changing household needs pushed more buyers towards completed resale flats. HDB resale prices rose 12.7% in 2021 and another 10.4% in 2022.
Private-property owners who sold their homes could enter the resale market with substantial sale proceeds. They were particularly competitive when bidding for larger and more expensive flats.
The wait-out period was introduced as a temporary measure to moderate that demand and give greater priority to buyers with more immediate housing needs, especially first-time buyers.
Singapore citizens aged 55 and above were exempted, but only when buying a four-room or smaller non-subsidised resale flat. Those who wanted a larger flat still had to serve the wait or appeal to HDB.
Since 2022, HDB processed about 1,800 appeals annually, approving roughly one in four. Successful appeals were mainly for households facing financial difficulties or exceptional circumstances without alternative housing options.
By 2026, conditions had changed. HDB resale-price growth slowed to 2.9% in 2025. The Resale Price Index then fell 0.1% in the first quarter of 2026 and another 0.3% in the second.
More flats are also reaching their Minimum Occupation Period and becoming available for resale. The Government therefore concluded that the temporary measure had served its purpose.
What changed—and what did not
Previously, the sequence was:
Sell the private property → wait 15 months → buy the HDB resale flat
Eligible owners can now do this:
Buy the HDB resale flat → sell the private property within six months
This makes it possible to move directly from a private home into an HDB flat. Owners no longer need to rent for 15 months or sell their existing home without knowing what replacement flat they can secure.
The previous size restriction is also gone. Older right-sizers are no longer limited to a four-room or smaller flat. They may consider a five-room flat, executive apartment or maisonette if they need space for a helper, home office or visiting family members.
However, this is not a blanket removal of every restriction.
The 30-month wait-out period still applies if you intend to buy:
- A new BTO flat, with or without housing grants
- A resale flat with CPF housing grants
- A resale flat using an HDB housing loan
- A new executive condominium directly from a developer
The change applies only to a non-subsidised HDB resale flat bought without an HDB loan.
Other important conditions remain:
- You must obtain a valid HDB Flat Eligibility letter before obtaining an Option to Purchase.
- You must dispose of all private residential properties in Singapore and overseas within six months of completing the HDB purchase.
- The five-year Minimum Occupation Period still applies.
- CPF usage and remaining-lease rules remain unchanged.
- Bank financing remains subject to MSR, TDSR, loan-to-value and loan-tenure requirements.
There is also an ABSD concession that is often overlooked.
For qualifying HDB purchases, ABSD is fully remitted if at least one purchaser is a Singapore citizen. For permanent residents acquiring an HDB flat, the remission generally reduces the ABSD payable to 5%.
The remission is usually granted through the HDB approval process. Qualifying purchasers therefore do not have to pay a large ABSD amount first and wait for a refund.
How many right-sizing plans go wrong.
The initial calculation may look simple. For example, you may think you can sell your condominium for $2M, buy an HDB flat for $850K and release $1.15M for retirement.
But $1.15M is only the difference between the two property prices. It does not account for the mortgage and all the costs of selling, buying and moving.
Suppose you still have a $400K mortgage and pay approximately $45K in agent commission and legal expenses. After deducting these amounts, your net property equity is only $1.555M.
Assume $650K must be refunded to your CPF accounts. Only the remaining $905K will reach your bank account as cash. The CPF money may still be used for the HDB purchase, subject to CPF rules, but that is not going to be your retirement funds.
The $850K HDB flat will also cost more than $850K. Buyer’s Stamp Duty on an $850K residential property is approximately $22K. After adding legal fees, renovation, furnishing and moving expenses, assume that the all-in cost of the replacement home is $980K.
The actual capital released is therefore:
$1.555M net property equity − $980K all-in replacement-home cost = approximately $575K
Assuming the $650K CPF refund can be fully used towards the replacement flat, you would need to pay another $330K from your $905K cash proceeds. This leaves approximately $575K in cash for your retirement.
The arithmetic now:
- Cash received after CPF refund: $905K
- Additional cash needed for the replacement home: $330K
- Cash remaining: $575K
The calculation is:
Capital released = Net equity from the private property − all-in cost of the replacement home
Instead of releasing the headline amount of $1.15M, you may have only about $575K left to support your retirement.
This is why the choice of replacement home matters. If you buy a $1.3M premium HDB flat and renovate it to the same standard as your condominium, most of the capital you hoped to release could disappear.
This is why some people may have changed their address, but they have not truly right-sized.
There is nothing wrong with paying more for space, location and convenience. But if the move does not meaningfully improve your retirement income, liquidity or financial security, it is primarily a lifestyle decision rather than a retirement-planning decision.
That may still be the right choice, but only if you have a clear understanding of the trade-off.
Should you use CPF or cash for the HDB flat?
After selling the private property, the next question is how to fund the replacement flat.
Should you use the CPF refund, cash proceeds, a bank loan or a combination?
There is no universal answer.
If you are below 55
The CPF principal and accrued interest refunded from the sale will generally be credited to your Ordinary Account.
Subject to CPF housing limits, those OA savings may be used to pay for the replacement flat. This preserves more cash outside CPF for emergencies, retirement spending or investment.
The trade-off is that CPF used for the property will no longer earn OA interest for your retirement, yet you have to pay back the accrued interest. Preserving cash is only helpful if that money is subsequently managed with discipline.
If you are 55 or above
The CPF housing refund will first be used to top up your Retirement Account to the Full Retirement Sum (FRS). Any balance will generally remain in your Ordinary Account and may be withdrawable, subject to CPF withdrawal rules.
You may still be able to use eligible OA savings for the replacement flat. However, that converts liquid CPF savings into an illiquid leasehold property.
On the other hand, paying entirely in cash may leave you with a smaller emergency reserve and less capital to generate retirement income.
The right combination depends on your:
- Expected retirement expenses
- CPF LIFE income
- Need for accessible cash
- Investment experience and risk tolerance
- Remaining lease of the HDB flat
Using CPF preserves cash. Using cash preserves CPF savings and guaranteed interest. The right decision can only be made by looking at the entire retirement plan.
Waiting risk has become execution risk
The Government has removed the waiting risk. It has not removed the execution risk.
Under the old rule, owners had to sell first. It was inconvenient, but they knew their actual sale proceeds before committing to the next home.
Buying first is more convenient, but it creates a different risk: you must sell all private residential properties within six months of completing the HDB purchase.
Before committing to a flat, ask:
- What if the condominium sells for less than expected?
- What if the sale takes longer than planned?
- Would the six-month deadline force you to accept a weaker offer?
- Do you have enough liquidity to complete the HDB purchase before receiving the sale proceeds?
Use a conservative sale price when modelling the move—not the highest asking price in your development.
You should also check whether Seller’s Stamp Duty applies. For private residential properties bought on or after 4 July 2025, the SSD holding period is four years, with rates ranging from 16% in the first year to 4% in the fourth year.
Long-term owners will usually be unaffected, but recent buyers should confirm their position before planning a sale. Check the current SSD rules.
The financing catch
Because the exemption is not available with an HDB housing loan, buyers who require financing must consider a bank loan.
The amount available may be affected by:
- The 30% Mortgage Servicing Ratio
- The 55% Total Debt Servicing Ratio
- Income and existing debt obligations
- Age and loan tenure
- Whether the private-property mortgage is still outstanding
The last point is particularly important. If you buy the HDB flat before selling the condominium, the existing mortgage may still be counted when the new loan is assessed. This can reduce the loan-to-value limit and increase the cash or CPF required.
Age does not automatically prevent someone in their late 50s from obtaining a housing loan. However, a shorter chosen tenure or a tenure that crosses the applicable age threshold may result in a lower LTV or higher monthly instalments, making the MSR harder to meet.
Apply for the HFE letter early. If you intend to use bank financing, obtain a valid Letter of Offer before exercising the Option to Purchase.
Choose the right home for the next phase of life
Right-sizing should be treated as a long-term decision.
The five-year MOP means you cannot immediately change your mind, sell the flat or acquire another private residential property.
After fulfilling the MOP, returning to private property is possible. But if a Singapore citizen retains the HDB flat and buys a private home, the purchase would generally attract the prevailing ABSD rate for a second residential property.
Selling the HDB flat first may avoid that second-property ABSD, but it brings another round of transaction costs and the risk that private-property prices have moved beyond reach.
The replacement flat should therefore suit the next phase of your life, not just your current budget. Consider:
- Accessibility and proximity to healthcare
- Distance from children and family
- Remaining lease
- Future mobility needs
- Space for a helper or visiting family members
- Transport and daily amenities
A cheaper older flat may release more capital today, but its shorter lease could limit future CPF usage and resale demand. The goal is to balance affordability, retirement capital and long-term suitability.
Will HDB resale prices jump?
I do not expect a broad-based surge. This is aligned with what property analysts expect after the rule change.
Around 13,500 flats are expected to reach their MOP in 2026, up from about 8,000 in 2025. Together with the BTO pipeline, this additional supply should help absorb some of the returning demand.
However, the impact is unlikely to be evenly distributed.
| Likely to receive stronger demand | Likely to see less impact |
|---|---|
| Five-room, executive and multi-generation flats | Older flats with shorter remaining leases |
| Newer flats with longer remaining leases | Smaller flats in less convenient locations |
| Mature, well-connected estates near MRT stations | Units with weaker accessibility or less desirable attributes |
Private-property right-sizers often have substantial sale proceeds and may be willing to pay for space, convenience and location.
The premium HDB segment was already strong before the rule changed. In the second quarter of 2026, 491 flats changed hands for at least $1M, even as the overall HDB Resale Price Index declined.
Before the wait-out period was introduced, private-property owners and former owners accounted for about 34% of million-dollar HDB buyers. That proportion fell to about 12% between January and November 2024.
The return of this group could support larger and premium resale flats. However, million-dollar transactions remain a small part of the overall market, and the additional MOP supply should help prevent a broad surge.
A two-speed market is therefore more likely: selected larger and well-located flats may remain firm while the broader resale market stays relatively stable.
Put it all together: The discipline must come from planning
Personally, I support the removal of the 15-month rule.
It was introduced as a temporary measure during an unusual period. By 2026, it had become a genuine obstacle for families with legitimate right-sizing needs.
But the old rule accidentally provided something useful: time.
Fifteen months forced owners to slow down, understand their actual sale proceeds and consider whether they were financially and emotionally ready for the move.
That compulsory pause has now gone. The discipline must therefore come from planning rather than policy.
Before right-sizing, you should be able to answer four questions:
- What will actually remain after repaying the mortgage and paying all transaction costs?
- Should the replacement home be funded with cash, CPF or a combination?
- How much capital will genuinely be released for retirement?
- What does that capital need to do next?
The last question is often overlooked.
Selling a condominium and leaving $575K in a savings account does not complete a retirement plan. It simply converts an illiquid property into liquid capital.
That capital needs to be given a job.
Using my Kueh Lapis Retirement Framework, the released capital can be structured into three layers:
- Guaranteed income for essential retirement expenses
- Variable income for regular lifestyle spending
- Bonus income from growth assets to address inflation and fund future goals
The purpose of right-sizing is not simply to move from a condominium into an HDB flat. It is to improve your retirement cash flow, liquidity and financial resilience.
The new rule gives you more flexibility. It does not automatically make right-sizing the correct decision.
Removing friction from a well-planned decision is helpful. Removing friction from an under-planned decision can be dangerous.
If you are considering right-sizing in the next few years, start by running your financial numbers: your CPF position, loan capacity, all-in replacement-home cost and the income your released capital needs to generate.
