Can You Afford to Upgrade?
Before anything else, run the numbers. A typical HDB-to-condo upgrade requires you to cover the gap between your HDB sale proceeds and the new condo cost, plus stamp duties and mortgage affordability.
Typical Upgrade Math: $1.5M Condo
Purchase price$1,500,000
Downpayment (25%)$375,000
Buyer's Stamp Duty$44,600
ABSD (with remission)$0
Legal fees~$3,000
Total upfront$422,600
Minimum cash (5%)$75,000
Most upgraders use: HDB sale proceeds (cash + CPF refund) → condo downpayment. The gap is covered by new CPF contributions and savings.
The 4 Big Rules to Know
1. Minimum Occupation Period (MOP)
You must live in your HDB for 5 full years before selling or buying private property. MOP is counted from key collection, not the purchase date. Any overseas posting, subletting, or major life event doesn't reset it. But it also doesn't pause it.
2. ABSD Remission (Critical)
Singapore Citizen married couples buying a replacement property qualify for ABSD remission if they sell the existing HDB within 6 months of the new purchase (or 6 months after TOP for new launches). This saves you 20% of the new property price. On a $1.5M condo, that's $300,000.
Miss the window → pay ABSD in full. No extensions.
3. MSR vs TDSR
MSR (30% cap) only applies to HDB and EC loans. Once you move to a private condo, only TDSR (55% cap) applies, which is more generous. This means your upgrade affordability is often higher than your HDB loan would allow.
4. CPF Valuation Limit
You can use CPF OA up to the property's Valuation Limit. Beyond that, you need cash. Older buyers or longer loan tenures hit the limit faster. Plan your cash buffer accordingly.
The 5 Steps of a HDB Upgrade
- Affordability check (Month 0). Get HDB valuation, bank IPA, CPF balance, and calculate total upfront + monthly commitments.
- List HDB and find buyer (Months 1-3). Price correctly based on recent transactions. Over-pricing adds 2-3 months of delay.
- Concurrent condo search (Months 2-4). Shortlist 5-10 units within budget. Attend showflats for new launches, viewings for resale.
- Sign OTP on condo, HDB resale timing (Months 4-5). Align completion dates. For new launches, there's no rush. You sell HDB after TOP.
- Completion and move (Months 6-11). HDB keys handed over, condo keys collected, ABSD remission application filed within 6 months.
HDB Resale vs New Launch: Which to Upgrade Into?
HDB Resale Condo: Move-in ready, you see what you're buying, known neighbourhood. But older building means possible renovation. Typical timeline: 3-4 months from OTP to key collection.
New Launch Condo: Brand new, modern facilities, often near MRT/schools for better long-term appeal. But 3-5 year wait for TOP and you're buying on plans. Progressive Payment Scheme means lower mortgage during construction.
For most HDB upgraders, new launches suit younger buyers (willing to wait, want lower progressive payments) while resale condos suit families needing to move in now.
Common Questions About HDB Upgrading
When can I upgrade from HDB to condo?
You can only sell your HDB flat and buy a private property after completing the 5-year Minimum Occupation Period (MOP). The MOP starts from the key collection date. Until MOP is reached, you cannot buy any private residential property, even if you intend to keep the HDB.
Can I keep my HDB and buy a condo?
Only after MOP, and you need to be financially able. You'll pay 20% ABSD as a Singapore Citizen buying a second property. Most upgraders sell the HDB first to avoid ABSD and free up CPF and cash for the condo purchase.
What is the ABSD remission for married couples?
Singapore Citizen married couples can apply for ABSD remission when buying a replacement condo, as long as they sell their existing HDB within 6 months of the new condo purchase (or 6 months after TOP for new launches). This saves $200,000-$400,000+ on a typical upgrade.
How much do I need to upgrade from HDB to condo?
For a $1.5M condo, budget: 25% downpayment ($375K, of which 5% must be cash), BSD $44K, ABSD $0 (with remission), legal fees $3K, agent fees handled by seller. Plus monthly mortgage typically $4K-$6K. Most upgraders use HDB sale proceeds + CPF + cash savings.
Can I use my CPF for the condo downpayment?
Yes. You can use CPF Ordinary Account funds up to the Valuation Limit. The minimum 5% cash downpayment is required regardless. After CPF usage, remaining downpayment can be cash or CPF up to the limits. Your HDB CPF refund will flow back into your CPF OA when you sell.
Should I sell HDB first or buy condo first?
For most upgraders, sell HDB first (or concurrently) to: (1) qualify for ABSD remission, (2) free up CPF proceeds, (3) show cleaner finances to the bank. Buying first requires substantial cash and incurs ABSD which may not be refundable if you miss the 6-month sell window.
What's the typical HDB upgrade timeline?
Planning: 2-3 months. List HDB and find buyer: 2-3 months. HDB completion: 2 months. Condo OTP to key collection (resale): 3 months. Total: 9-11 months. For new launches, add construction timeline (3-5 years) but you only need to sell HDB after TOP for ABSD remission.
