Quick Answer
Upgrading from HDB to condo in Singapore involves 8 steps: confirm MOP eligibility, calculate net proceeds, assess financing, decide sell-first or buy-first, list your HDB, secure your condo, complete both transactions, and move in. The full process typically takes 6–9 months. Getting steps 1–3 right before anything else is what separates a smooth upgrade from a costly one.
Introduction
The HDB-to-condo upgrade is one of the most significant financial moves a Singaporean household will make. It is also one of the most sequentially sensitive — do things in the wrong order and you either miss the condo you want or carry two sets of financing costs longer than necessary.
This is the exact step-by-step process, including what to verify at each stage and where most people get it wrong.
What Do I Need to Check Before I Start the Upgrade Process?
Step 1: Confirm your MOP is fulfilled You cannot list your HDB for sale until your Minimum Occupation Period — typically 5 years from key collection — is completed. Verify your exact MOP end date via My HDBPage before doing anything else. Getting this wrong can derail your entire timeline.
Step 2: Calculate your net proceeds Before you start condo browsing or speak to a bank, establish your real net proceeds from the HDB sale. This means: expected sale price minus outstanding loan, minus CPF refund (principal + accrued interest at 2.5% p.a.), minus agent commission, minus legal fees. This number — not your sale price — determines your upgrade budget.
Step 3: Assess your borrowing capacity Under the Total Debt Servicing Ratio (TDSR) framework, your total monthly debt obligations (including the new mortgage) cannot exceed 55% of your gross monthly income. If you have a car loan, renovation loan, or any other credit facility, these reduce your eligible mortgage quantum. Get an In-Principal Approval (IPA) from a bank before committing to any property.
Should I Sell My HDB First or Buy the Condo First?
This is the most consequential tactical decision in the entire upgrade process, and the right answer depends on your financial buffer, risk tolerance, and whether you are targeting a new launch or a resale condo.
Sell first: You know exactly what you have. Your net proceeds are confirmed, your CPF refund is in your account, and you can make a condo offer with certainty. The downside: you may need interim accommodation if there is a gap between your HDB completion and condo key collection. For resale condos, a 6–9 month timeline can usually be negotiated to minimise this gap.
Buy first (common for new launch condos): New launch condos have progressive payment schedules — you pay in stages as construction milestones are hit. This means you can exercise the Option to Purchase now and have 3–5 years before the full balance is needed. A bridging loan covers the interim period until your HDB proceeds are released. The risk: your HDB sale price is not yet confirmed when you commit to the condo price.
For most first-time upgraders without a large cash buffer, sell-first is the lower-risk path.
What Are the Exact Steps Once I Have Decided to Proceed?
Step 4: Appoint a CEA-licensed property agent Choose an agent (or agency) who can handle both your HDB sale and your condo purchase — ideally under a coordinated model so both timelines are managed together. This prevents the scenario where your HDB sells faster than expected and you have nowhere to move into, or where your condo purchase completes but your HDB has not sold.
Step 5: List your HDB and set the right price Your agent should pull comparable transacted prices for similar flats in your area within the last 3–6 months. Pricing too high increases days-on-market and can stigmatise the listing. Pricing accurately generates multiple offers quickly, which gives you negotiating position.
Typical timeline from listing to Option to Purchase (OTP): Within 1–8 weeks in active markets. Though some units may require a longer time frame of around 3 months. Speak to your agent to have an idea of the turnaround time for your particular unit.
Step 6: Accept an OTP and begin the HDB sale process Once a buyer exercises the OTP, the formal sales process begins. HDB resale transactions typically take 3 - 4 months from OTP to completion. During this window, your buyer secures their financing, HDB approves the resale, and legal completion is scheduled.
Step 7: Identify and commit to your condo With your HDB sale confirmed (or near confirmed), you can approach condo purchases with certainty about your budget. For resale condos, negotiate a completion date that aligns with your HDB sale. For new launches, your progressive payment schedule gives you more flexibility.
Step 8: Legal completion and move Both transactions complete, CPF Board releases your refund to your OA (Around 21 days or shorter post-HDB completion), and your condo loan begins drawing down. If there is a gap between your HDB handover and condo key collection, plan interim accommodation early — serviced apartments or staying with family are the most common solutions.
How HomeUp Approaches This
HomeUP operates on a coordinated sell-buy model — we manage both your HDB exit and your condo entry as a single planned process rather than two sequential independent transactions.
Most upgraders who come to us have started with the condo. They have attended showflat launches, fallen in love with a unit, and then started wondering if they can afford it. We reverse this: we start with your HDB, establish your true budget, and then find you a condo that works within it. This sequence prevents the most common and costly upgrading mistake — committing to a condo price before knowing your confirmed proceeds.
Our fixed fee of $1,999 for the HDB sale versus the industry-typical 1% commission means more of your sale proceeds stay with you. On a $650,000 HDB, that is a $4,501 saving. On a $750,000 flat, a $5,501 saving.
The upgrade process is not complicated when you follow the right sequence. The mistakes happen when steps are skipped or done out of order.

FAQ
How long does the full HDB-to-condo upgrade process take?
From first planning call to moving into the condo, most upgrades take 6 months or more. Resale-to-resale transactions can be faster (around 6 months). HDB sale to new launch condo can be shorter (3–5 months to commit, then 3–5 years to completion).
Do I pay ABSD when upgrading from HDB to condo?
If you sell your HDB before or simultaneously with purchasing the condo, you own only one property and pay no ABSD as a Singapore Citizen. If you buy the condo before fully disposing of your HDB, you technically own two properties and ABSD applies — though it can be remitted upon HDB sale completion within 6 months.
Can I use my CPF refund for the condo downpayment?
Yes, once the CPF refund clears back into your OA after the HDB sale (10–14 days), you can use it toward your condo purchase downpayment.
What is an In-Principal Approval (IPA) and do I need one?
An IPA is a conditional loan approval from a bank confirming how much they will lend you, based on your income and liabilities. You should get one before committing to any condo purchase. It costs nothing and takes 1–3 working days.
Is it possible to complete an HDB upgrade in under 6 months?
Possible, but tight. Both resale transactions would need to progress quickly and be well-coordinated. New launches allow more flexibility in timing since downpayment and progressive payments are spread out.
