Effective 28 July 2026 — with immediate effect

The 15-month HDB wait-out was abolished on 28 July 2026

Most of what is written online about private property owners buying HDB resale flats still describes a rule that stopped applying on 28 July 2026. Here is the current position, what did not change, and the trap the change creates.

The rule, as of 28 July 2026

The 15-month wait-out is gone. Private property owners and former owners can buy a non-subsidised HDB resale flat with no wait — if they take no HDB housing loan.

The Ministry of National Development and HDB removed the wait-out with immediate effect on 28 July 2026. Until 27 July 2026, a private residential property owner (PPO) or former owner buying a non-subsidised resale flat had to wait 15 months after disposing of the private property. Buyers aged 55 and above moving to a 4-room or smaller resale flat were already exempt from that wait. From 28 July 2026 the wait is zero months, for all ages and all flat types on that route.

What you must wait after disposing of your private property
What you want to buyFrom 28 July 2026Until 27 July 2026
Non-subsidised resale flat, no HDB housing loan, no CPF housing grants0 months15 months (0 if aged 55+ into a 4-room or smaller flat)
Resale flat with CPF housing grants30 months30 months
Resale flat with an HDB housing loan30 months30 months
Any new HDB flat30 months30 months
New Executive Condominium from a developer30 months30 months

The 30-month bar was not touched. Read it carefully, because it is where the saving disappears: wanting either CPF housing grants or an HDB housing loan on the resale flat puts you back on a 30-month wait from disposal. The route that has no wait is the one where you finance the flat yourself.

If you still own the private property

A current owner does not have to sell before buying — but HDB requires all private residential property, in Singapore or overseas, to be disposed of within 6 months of completing the HDB resale purchase.

The trap this creates

A zero-month HDB wait-out is not ABSD clearance. These are two different rules on two different clocks.

HDB’s 6-month disposal window runs from the completion of your HDB resale purchase. IRAS assesses Additional Buyer’s Stamp Duty (ABSD) at the point of purchase — when the option is exercised. So an owner who exercises the option on a resale flat while still holding the condominium is buying a second property in IRAS’s eyes, and pays second-property ABSD on it, even though HDB is perfectly happy with the timing.

Pending applications for an HDB Flat Eligibility letter were updated automatically, and existing valid holders are unaffected where their purchase plans have not changed.

Worked example

  • BuyersMarried couple, both Singapore Citizens
  • Currently ownA condominium, not yet sold
  • BuyingA resale flat at S$780,000, no HDB housing loan, no CPF housing grants
  • Option on the flat exercised1 November 2026

HDB’s answer

  1. Route: non-subsidised resale flat, no HDB housing loan, no grants
  2. Wait-out required from 28 July 2026 = 0 months — they may buy now
  3. Condition attached: dispose of the condominium within 6 months of completing the flat purchase
  4. Under the old rule they would have had to sell first and then wait 15 months

IRAS’s answer, on the same day

  1. Residential properties owned on 1 November 2026, when the option is exercised: 1
  2. The flat is therefore their 2nd residential property; Singapore Citizen rate 20%
    ABSD = 20% × S$780,000 = S$156,000
  3. Buyer’s Stamp Duty:
    1% × first S$180,000 = S$1,800
    2% × next S$180,000 = S$3,600
    3% × remaining S$420,000 = S$12,600
    BSD total = S$18,000
  4. Duty payable up front = S$156,000 + S$18,000 = S$174,000
  5. Had the condominium’s sale contract been executed first, ABSD would be S$0 and the duty would be S$18,000

The answer HDB says they can buy today. IRAS says that buying today, in that order, costs S$156,000 in ABSD. The wait-out being abolished changed the first answer and not the second.

What changes this answer

  • Whether you want CPF housing grants or an HDB housing loan. Either one puts you on the 30-month wait from disposal. This is the fact that most often turns a “no wait” into a two-and-a-half-year wait.
  • Whether the flat is subsidised or non-subsidised. The zero-month route is the non-subsidised resale route only.
  • Whether you still own the private property. If you do, the 6-month disposal condition attaches — and the ABSD question above becomes live.
  • The order in which the two contracts are executed. Selling before exercising the option on the flat is what removes the ABSD, not the HDB rule change.
  • Whether you already hold an HDB Flat Eligibility letter. Valid holders are unaffected where plans are unchanged; pending applications were updated automatically.
  • Property held overseas. The disposal condition covers private residential property in Singapore or overseas.

Common follow-up questions

How long must a private property owner wait to buy an HDB resale flat?

From 28 July 2026, there is no wait for a non-subsidised resale flat bought without an HDB housing loan and without CPF housing grants, at any age and for any flat type. Before that date the wait was 15 months, with an exemption for buyers aged 55 and above moving to a 4-room or smaller flat.

Does the 30-month wait still exist?

Yes, and it was not changed. A 30-month wait after disposing of the private property still applies if you want CPF housing grants on the resale flat, if you want an HDB housing loan, if you are buying any new HDB flat, or if you are buying a new Executive Condominium from a developer.

Do I have to sell my private property before buying the resale flat?

Not before buying, but all private residential property in Singapore or overseas must be disposed of within 6 months of completing the HDB resale purchase.

If HDB lets me buy now, do I still pay ABSD?

Yes, if you still own the private property when you exercise the option on the flat. HDB's disposal window runs from the completion of your HDB purchase, while IRAS counts your properties at the point of purchase. A zero-month wait-out is not ABSD clearance.

What happens to an HDB Flat Eligibility letter applied for before the change?

Pending applications were updated automatically, and existing valid holders are unaffected where their purchase plans have not changed.
