Thinking of selling your HDB and upgrading to a condo?
Sell HDB and Buy. Maybe you need more space. Maybe you want facilities like a pool and gym. Or maybe you are planning long-term wealth growth.
Whatever the reason, one big question usually comes up:
“How long will the whole process take?”
You are not alone in asking this. The timeline can feel complicated, but when broken down clearly, it becomes much easier to plan with confidence.
1. Check Your Minimum Occupation Period (MOP) First
Before anything else, confirm that you have fulfilled your 5-year Minimum Occupation Period (MOP).
Without meeting MOP, you cannot legally sell your HDB flat. You can verify your eligibility directly through the Housing & Development Board portal.
If MOP is completed, you are ready to move forward.
Estimated time: Immediate check
2. Financial Planning and Affordability Assessment (2–4 Weeks)
Before listing your HDB, review your finances carefully.
Key things to calculate:
- Outstanding HDB loan or bank loan
- CPF refund amount with accrued interest
- Estimated cash proceeds
- Condo downpayment (usually 25%)
- Buyer’s Stamp Duty
You may also want to get an In-Principle Approval (IPA) from a bank to understand your condo loan eligibility.
This planning stage is critical because it determines whether you should:
- Sell first, then buy
- Buy first, then sell (requires strong cash flow)
Estimated time: 2 to 4 weeks
3. Selling Your HDB Flat (8–12 Weeks)
Once ready, you can list your HDB for sale.
Typical timeline:
Week 1–4: Marketing and buyer viewings
Week 4–8: Receive offer and grant Option to Purchase (OTP)
Week 8–12: HDB resale submission and approval
The entire resale process through the Housing & Development Board usually takes about 8 weeks after submission.
Total selling timeline: Around 2 to 3 months
4. Buying Your Condo (8–12 Weeks)
If you buy a resale condo, the private property transaction is generally faster than HDB.
Timeline usually looks like this:
- Week 1: Secure OTP
- Week 2–3: Exercise OTP
- Week 8–12: Completion
For new launch condos, the timeline depends on the construction stage and TOP date.
You will also need to pay Buyer’s Stamp Duty to the Inland Revenue Authority of Singapore within 14 days of signing, thus I would usually remind buyers to factor this into their financial planning early. Contact me for a free timeline mapped out for you.
Estimated timeline: 2 to 3 months
5. Coordinating Sell and Buy: The Critical Part
This is where planning matters most.
There are generally three approaches:
- Sell First, Then Buy
Lower financial risk
May need temporary housing
- Buy First, Then Sell
Requires a strong financial buffer
May incur Additional Buyer’s Stamp Duty (ABSD) if not planned properly
- Simultaneous Completion
Carefully coordinated timelines
Most common strategy
Many sellers aim to align HDB completion with condo completion on the same day to avoid temporary moves.
7. Common Mistakes That Delay the Timeline
- Not checking MOP early
- Overestimating the HDB sale price
- Underestimating cash needed for condo
- Poor coordination of completion dates
These mistakes can easily stretch your timeline beyond six months.
So, When Should You Start?
If you are thinking about upgrading within the next year, planning should start now.
The most important step is understanding your numbers clearly before making commitments.
If you share your flat type, estimated selling price, outstanding loan, and target condo budget, a clearer timeline can be mapped out.
Selling your HDB and buying a condo is not just a transaction. It is a transition.
With the right sequence and timing, it can be smooth, strategic, and financially sound.
