Selling Your Current Property to Buy Thomson Reserve: What Will You Actually Net?
For most Thomson Reserve buyers, the purchase is funded – at least in part – by the sale of an existing property. Whether you are selling an HDB flat or a current private property, the figure that matters is not the sale price. It is what remains in your hands after the outstanding loan is repaid, CPF is refunded, and all transaction costs are settled.
This free sales proceeds calculator gives you that figure – split cleanly between net cash deposited to your bank account and CPF returned to your Ordinary Account. Know your real starting position before you decide whether Thomson Reserve works within your financial plan, and which unit type your budget can comfortably reach.
Why the Sale Price Is Not What You Actually Receive
1. Outstanding Loan Repayment
If you have an outstanding housing loan – whether an HDB concessionary loan or a bank loan – the outstanding balance is repaid in full from your sale proceeds at completion.
2. CPF Refund (Principal + Accrued Interest)
Every dollar of CPF Ordinary Account savings used to purchase your property must be refunded to your CPF account when you sell – including the principal plus accrued interest calculated as if that money had remained in your OA earning 2.5% per annum, compounded. For a flat purchased 10 to 15 years ago with significant CPF usage, this accrued interest adds tens of thousands of dollars on top of the principal.
Example: If you withdrew $200,000 in CPF over 12 years, the accrued interest at 2.5% compounded is approximately $63,000. You refund $263,000 to CPF, not $200,000.
3. Property Agent Commission
The standard market commission is 2% of the sale price, paid by the seller. On a $700,000 HDB, this is $14,000.
4. Legal and Conveyancing Fees
Legal fees for HDB resale transactions are typically $2,000 to $3,500. Private property conveyancing fees vary by law firm and sale price.
What Happens to the CPF Refund?
The CPF refund goes back into your CPF Ordinary Account – not to you in cash. The refunded CPF (principal + accrued interest) is credited to your OA after sale completion, typically within 2 to 4 weeks. You can then use these CPF OA funds toward the Thomson Reserve downpayment or monthly mortgage instalments.
Your proceeds consist of two distinct pots: net cash (spendable, in your bank account) and CPF OA refund (returned to CPF, usable for the next property but not withdrawable as cash unless above 55 and above the Full Retirement Sum).
The Timing Question: Sell Before or After Buying Thomson Reserve?
Selling first means 0% ABSD and 75% LTV for Singapore Citizens – better loan terms and no stamp duty burden upfront. But you need alternative accommodation until Thomson Reserve’s estimated TOP in 2030. Buying Thomson Reserve first allows you to secure your preferred unit immediately but requires paying 20% ABSD in cash upfront, claimable as a refund for married Singapore Citizen couples who sell within 6 months of TOP.
Minimum Occupation Period (MOP) – Are You Eligible to Sell?
Before you can sell your HDB flat on the open market, you must have completed the Minimum Occupation Period: 5 years from key collection for standard HDB flats, and 10 years for Prime Location Public Housing (PLH) flats. The calculator includes an MOP eligibility check – enter your key collection date to confirm whether you are eligible.
Will Your Property Sale Proceeds Be Enough for Thomson Reserve?
Once you have your net cash and CPF refund, the next question is whether those figures cover the upfront costs of your preferred unit. Based on indicative analyst pricing:
1. Targeting a Unit between $1.8M to $2.2M
Minimum cash needed: 5% booking fee ($90,000 to $110,000) plus BSD ($48,600 to $59,600) – total approximately $138,600 to $169,600. Your CPF OA refund from your HDB sale covers the 20% balance downpayment. If your HDB net cash is below $140,000 after all deductions, you may need to supplement with savings.
2. Targeting a Unit between $2.5M to $3.2M
Minimum cash needed: 5% booking fee ($125,000 to $160,000) plus BSD ($79,600 to $104,600) – total approximately $204,600 to $264,600. Most upgraders at this tier supplement HDB net cash with accumulated savings. If ABSD applies, add 20% of purchase price in additional cash.
3. Targeting a between $3.5M to $6M
At this price range, HDB proceeds alone rarely cover the full cash requirement. Most buyers at this tier are transacting from an existing private property – or combining HDB proceeds with significant savings. The calculator handles both HDB and private property sale scenarios.

Frequently Asked Questions
What does the sales proceeds calculator compute?
The calculator computes your net cash in hand and CPF OA refund after selling your current property. It deducts your outstanding housing loan balance, CPF principal withdrawn, accrued CPF interest (compounded at 2.5% per annum), property agent commission, legal fees, and HDB resale levy (if applicable) from your gross sale price. The result is split into two figures: net cash proceeds (deposited to your bank account) and CPF refund (credited back to your CPF Ordinary Account).
Why do I have to refund CPF when I sell my HDB flat?
When you sell your HDB flat, you must refund all CPF Ordinary Account funds used for the purchase – both principal and accrued interest at 2.5% per annum compounded – back to your CPF account. For example, $200,000 in CPF usage over 12 years generates approximately $63,000 in accrued interest, so you refund $263,000 to CPF. This refund is not received as cash but can be reused for your Thomson Reserve purchase.
What is the difference between net cash proceeds and CPF refund?
Net cash proceeds are deposited to your bank account and can be used freely – for the Thomson Reserve booking fee, BSD, ABSD (if applicable), or other expenses. The CPF refund goes back to your CPF Ordinary Account and cannot be withdrawn as cash (unless above 55 and above the FRS), but can be used for the Thomson Reserve downpayment and monthly mortgage instalments.
Do I need to pay ABSD when upgrading from HDB to Thomson Reserve?
If you sell your HDB before buying Thomson Reserve, Singapore Citizens pay 0% ABSD. If you buy Thomson Reserve first while still owning the HDB, ABSD of 20% applies and must be paid in cash within 14 days of signing the Sale and Purchase Agreement. Married SC couples who buy first can apply for ABSD remission if the HDB is sold within 6 months of Thomson Reserve’s estimated TOP in 2030 — but the ABSD must be paid upfront first and claimed back later.
What is the Minimum Occupation Period (MOP) for HDB flats?
The MOP is 5 years from key collection for most HDB flats, and 10 years for Prime Location Public Housing (PLH) flats. During the MOP, you cannot sell your HDB, rent out the entire flat, or own private property in Singapore. Confirm your MOP completion date using by checking from HDB Portal wiht your SingPass while planning your Thomson Reserve purchase timeline.
What is the HDB resale levy and does it apply to me?
The HDB Resale Levy applies if you previously received a housing grant and are buying another subsidised flat or EC. It does not apply if you are upgrading to a private property like Thomson Reserve. The calculator includes a toggle – disable it for your Thomson Reserve upgrade.
Should I sell my HDB before or after buying Thomson Reserve?
Selling first gives Singapore Citizens 0% ABSD and 75% LTV – better loan terms and no upfront stamp duty burden. The trade-off is accommodation: with Thomson Reserve’s estimated TOP in 2030, you could be renting in Upper Thomson for up to 4 years at $3,000 to $5,000 per month for a family-sized apartment. Buying at approximately $2M first means 20% ABSD upfront in cash – on a $2M unit, that is $400,000 – claimable as a refund for married SC couples who sell the HDB within 6 months of TOP.
Will my HDB sale proceeds cover the Thomson Reserve (at approximately $2M) booking fee and stamp duty?
For a Thomson Reserve unit at approximately $2M, your minimum upfront cash requirement is approximately $154,600 — comprising the 5% booking fee ($100,000) and BSD ($54,600). For many HDB sellers in the $600,000 to $800,000 price range with 10 to 15 years of ownership, net cash proceeds fall between $100,000 and $300,000 depending on CPF usage. The calculator gives you the accurate figure for your specific situation.
I am a PR selling a private property to upgrade to Thomson Reserve. How does this calculator apply?
The calculator supports private property sale scenarios. For PRs or investors selling a private condo before purchasing Thomson Reserve, the key deductions are the outstanding bank loan, CPF refund (principal plus accrued interest), and Seller’s Stamp Duty (SSD) if the property is sold within 3 years of purchase. SSD rates are: 12% if sold within 1 year, 8% in the second year, 4% in the third year, and 0% after 3 years. Toggle the SSD field in the calculator to include this in your net proceeds calculation.
How do I use my sales proceeds to decide which Thomson Reserve unit type I can afford?
Once you have your net cash and CPF refund from this calculator, bring both figures into the Affordability Calculator at /affordability-calculator/ to find your maximum loan. Your net cash covers the 5% mandatory booking fee, BSD, and ABSD (if applicable). Your CPF OA refund covers up to 20% of the purchase price as downpayment. Together with your maximum loan, this tells you the highest-priced Thomson Reserve unit you can comfortably transact — whether a 2-bedroom, 3-bedroom or larger.
