Before You Do Anything: Check These 3 Numbers
Most HDB owners who come to us asking about upgrading make the same mistake — they start browsing condos before they know what they can actually afford. Three numbers determine everything: your MOP status, your CPF OA balance after refund, and your remaining loan eligibility.
1. MOP date — Are you past 5 years from key collection?
2. Net proceeds — Sale price minus outstanding loan, minus CPF refund (principal + 2.5% p.a. accrued interest), minus selling costs.
3. Loan capacity — Based on your combined income and existing obligations (TDSR 55%).
Step 1: Confirm Your MOP
You must have lived in your HDB flat for a minimum of 5 years before you can sell it on the open market. The clock starts on the day you collect your keys (for BTO) or the date of resale completion (for resale HDB).
What you cannot do before MOP:
- Sell your HDB flat
- Rent out the entire flat (renting individual rooms is allowed)
- Buy any residential property in Singapore — private condo, landed, resale HDB, or EC
- Buy any residential property overseas
Path A: Sell HDB → buy private condo. Most common upgrader path. No ABSD if HDB is sold first. This guide covers Path A in full.
Path B: Sell HDB → buy resale HDB. Right-sizing, relocating, or unlocking equity to invest elsewhere. No resale levy when moving to a resale flat. Grant eligibility depends on first/second-timer status — see Step 3.
Path C: Sell HDB → buy industrial property. No ABSD on commercial/industrial (non-residential). Gross yields of 6–7% are achievable from entry prices around $132,000. A fundamentally different investment thesis — see our industrial property guide.
Path D: Keep HDB, buy condo. You retain the flat and purchase a second property simultaneously. The 20% ABSD applies immediately — on a $1.5M condo, that’s $300,000 upfront.
Step 2: Know Your Actual Numbers
CPF Refund: The Number That Surprises Most Upgraders
When you sell your HDB, all CPF funds used for the flat must be refunded to your CPF Ordinary Account before you receive any cash proceeds. This includes the original principal withdrawn plus accrued interest at 2.5% per annum — the CPF OA rate, fixed regardless of whether you have an HDB or bank loan.
The longer you’ve owned your flat, the larger this refund figure becomes. A flat bought in 2015 with $200,000 in CPF used would require roughly $255,000+ returned to CPF by 2026. You don’t lose this money — it goes back into your CPF OA and can be used for your next property — but it reduces your immediate cash proceeds significantly.
CPF accrued interest: 2.5% p.a. This is what gets added to your CPF refund. It’s set by CPF Board and does not change with your loan type.
Your loan interest rate is separate: HDB concessionary loan is 2.6% p.a.; bank loan rates vary (~3–4% currently). Your outstanding loan balance comes from your loan statement.

Estimating Your Net Proceeds
| Component | Example ($600k HDB) | Notes |
|---|---|---|
| Sale price | $600,000 | Market price |
| Less: Outstanding loan | –$80,000 | HDB or bank loan; fully repaid at completion |
| Less: CPF refund (principal + interest) | –$220,000 | Returns to CPF OA at 2.5% p.a. accrued |
| Less: Agent commission (2% + 9% GST) | –$13,080 | Standard market rate |
| Less: Legal fees | –$2,500 | $1,800–$5,000 range |
| Less: HDB admin fees | –$200 | $40–$200 + $120 processing |
| Cash proceeds | $285,300 | Actual cash in hand |
| CPF OA (available for next purchase) | $220,000 | From refund above |
| Total for next property | $505,300 | Cash + CPF combined |

Bank loan note: If you have a bank loan (not HDB loan), check for early redemption penalties before fixing your sale timeline. HDB loans have no early repayment penalty.
Condo Downpayment + Buyer Stamp Duty
For a bank loan (LTV 75%), you need at least 25% of the purchase price as downpayment — minimum 5% in cash, up to 20% from CPF OA. But Buyer Stamp Duty (BSD) is a significant additional cash cost that many upgraders underestimate.
| Condo Price | Min Cash (5%) | CPF (up to 20%) | Loan (75%) | BSD | Total Cash Needed |
|---|---|---|---|---|---|
| $1,000,000 | $50,000 | $200,000 | $750,000 | $24,600 | $74,600 |
| $1,500,000 | $75,000 | $300,000 | $1,125,000 | $44,600 | $119,600 |
| $2,000,000 | $100,000 | $400,000 | $1,500,000 | $69,600 | $169,600 |
BSD must be paid in cash — it cannot come from CPF. At $1.5M, your BSD of $44,600 is on top of the $75,000 minimum cash downpayment. This is the number that most often catches upgraders off-guard.
First $180k: 1% · Next $180k: 2% · Next $640k: 3% · Next $500k: 4% · Next $1.5M: 5% · Above $3M: 6%
Step 3: Resale Levy & Grant Status
If you’re selling your HDB and buying a private condo, you pay no resale levy. Full stop. Levy only applies when your next purchase is another subsidised flat — a new BTO or EC from HDB.
| Flat Type Previously Owned | Levy (buying new BTO/EC) | Levy (buying resale) |
|---|---|---|
| 2-room flat | $15,000 | None |
| 3-room flat | $30,000 | None |
| 4-room flat | $40,000 | None |
| 5-room flat | $45,000 | None |
| Executive / Maisonette | $50,000 | None |
| Executive Condominium (EC) | $55,000 | None |
Sell first, then buy: pay in cash at key collection of the new flat.
Buy first, then sell: levy is deducted from your HDB sale proceeds. Any shortfall must be paid in cash.
First-Timer vs Second-Timer: What It Means for Grants
Buying any subsidised flat (BTO/EC) — even without claiming grants — or receiving CPF Housing Grants on a resale HDB makes you a second-timer. The BTO’s below-market price is itself treated as a housing subsidy. This affects what grants you can access on your next purchase.
Full first-timer (never owned any flat, never received grants): EHG up to $120k + CPF Housing Grant up to $50k + PHG up to $30k.
Second-timer alone (previously owned BTO/EC, or received grants on resale): EHG and CPF Housing Grant unavailable. PHG ($30k living with / $20k within 4km of parents or child) is the only major grant — no income ceiling.
Mixed couple (one first-timer + one second-timer buying jointly): Half the EHG (up to $60k) + half the CPF Housing Grant + full PHG.
Resale buyer who skipped grants: If you bought a resale HDB without claiming any CPF Housing Grants, you remain a first-timer — no levy when later buying a BTO, and you can still access full grants on that BTO. Deliberately skipping grants on your first resale preserves this status.
Step 4: Sell First or Buy First?
This is the decision most upgraders agonise over. Both paths have real trade-offs.
If you buy the condo before selling your HDB, the 20% ABSD is paid upfront. Married couples (SC + SC or SC + SPR) purchasing the condo in joint names can apply to have it refunded, provided the HDB is sold within 6 months of the condo’s TOP (new launch) or purchase date (resale condo).
Single buyers have no remission route. If you’re single, you must sell your HDB before purchasing to avoid the 20% ABSD.
Step 5: Shortlist Your Condo
Once you know your budget, two decisions shape everything: leasehold vs freehold and new launch vs resale.
Leasehold (99yr) vs Freehold
For most upgraders, leasehold is the practical choice — it buys more space, a better location, or a lower monthly mortgage for the same budget. Leasehold condos in Singapore have historically delivered stronger percentage price appreciation than freehold equivalents, partly because the lower entry price amplifies returns and partly because leasehold projects are typically in more central, in-demand locations. If long-term inheritance or maximum tenure is your priority, freehold makes sense. But for upgraders optimising for cashflow and space, the leasehold discount is a feature, not a compromise. We cover the full data in our Leasehold vs Freehold guide.
New Launch vs Resale
New launches let you pick your unit before completion and pay progressively as construction milestones are hit — the full sum is not needed on day one. You get a brand-new flat with a fresh 99-year lease. The trade-off: you’re buying from floor plans and show flat, and you may wait 3–4 years before moving in — which matters if you’ve already sold your HDB.
Resale condos are immediately available. You see the actual unit, the actual view, the actual neighbours. For upgraders who need to move quickly after selling their HDB, resale removes the waiting risk entirely. The trade-off: shorter remaining lease and you’re paying today’s market price with no developer early-bird buffer.
We cover both in detail in our New Launch vs Resale Condo guide. Browse actual resale transaction data by budget: Under $1M · $1M–$2M · $2M–$3M · $3M–$4M
