When selling one HDB flat to buy another, compare the dates when money is needed with the dates when you can actually use it. The agreed sale price, net cash proceeds and CPF housing refund are three different figures. A move can look affordable overall and still have a payment due before the funds intended for it become available.
Build a sale timeline and a purchase timeline. Include your present home’s completion, your next home’s option and completion dates, and the confirmed arrangements for cash and CPF. Ask HDB or your acting solicitor how the transactions will work together before assuming they can be timed on the same day.
- Calculate expected net cash and the CPF refund separately.
- Record when each payment on the next purchase is due.
- Verify what cash and CPF you can use at each date.
- Ask whether a linked arrangement applies and which costs it can cover.
- Plan the handover and the move alongside the financing.

Start with the sale figures you can verify
Look at your expected sale price, outstanding housing loan, CPF housing refund and other applicable deductions. CPF Board’s housing refund guide explains how sale proceeds are used and how CPF amounts used for housing generally need to be refunded with accrued interest. Use the CPF Home ownership dashboard for figures specific to you and check the latest outstanding loan amount through the appropriate source.
If the proceeds may fall short of the expected CPF refund after paying the outstanding housing loan, use CPF Board’s guidance on insufficient proceeds. Selling at market value and selling below market value can have different consequences. Ask about the treatment of option monies and other items in your transaction. Get a transaction-specific estimate before treating a low-cash outcome as settled.
A CPF refund is credited to CPF, subject to the applicable rules. Check how much may be available for use on the next home, including age-related considerations if relevant. CPF Board’s guide to what you can do with refunded proceeds is a starting point.

The cash paid when an option is granted or exercised may be due before the sale of your current flat completes. Other payments arise later. Ask for a schedule for your specific purchase and label each amount by source. Separately record estimates for moving, temporary accommodation and essential work.
| Date or milestone | Amount to confirm | Funding question |
|---|---|---|
| Purchase option granted or exercised | Applicable option and exercise payments | What cash is already available? |
| Current home completes | Expected net cash and CPF refund | When and how can each amount be used? |
| Next home completes | Purchase balance, fees and financing | Which approved funds will cover each amount? |
| Keys and possession | Interim rent, movers and essential work | Is there a gap between legal completion and usable housing? |
Give each amount a status such as estimated, confirmed, paid or available. A confirmed date for an appointment may still leave an open question about which money can be applied on the day. Ask the person handling the transaction what event makes the funds available for that purpose.

HDB’s Enhanced Contra Facility guidance describes an arrangement that can allow eligible households to sell an existing HDB flat and buy another resale HDB flat using eligible sale proceeds and refunded CPF savings at the same time. Read the eligibility and application requirements for your circumstances and check the facility terms.
Ask which payments the arrangement can support, which payments are due before it can operate and what happens if either transaction changes. Financing choices and details of the related transactions matter. If you are applying for a second HDB housing loan, check HDB’s housing loan guidance for the applicable rules on CPF refunds and cash proceeds.

Worked example where the money arrives later than needed
A family estimates that it will have $65,000 in net cash after selling its existing flat. It has $12,000 in cash available today. In its illustrative timeline, it needs $16,000 in cash for various next-home and moving commitments before it can use the sale proceeds. The family has a $4,000 timing gap even though it expects more than that from the sale.
It checks which payments can be deferred or rescheduled, what it must pay under the purchase arrangements and whether a confirmed financing or transaction arrangement applies. It also rechecks the handover date. If the next flat is only usable after essential repairs, the family needs a cash allowance for the interim stay even if both property transactions complete close together.
The result is two decisions. Can the family cover each payment on the date it falls due? Can it manage the housing and school routine between the two homes? Working through both questions early gives the family time to change the sequence.

Rehearse a one-week slip
Take the purchase and sale calendars and move one expected event by a week. Ask what changes if the sale completes later, if the next flat is handed over later, or if a payment arrives on a different day than you expected. Test each change independently so you know which problem requires a financing answer and which requires a housing answer.
For the financing question, identify the first bill that would be affected and the person who can confirm the applicable arrangement. For the housing question, identify where the household would stay and which movers, contractors or caregivers need to be told. Test the school and work journeys from that interim address where relevant.
A useful family note includes the original date, the changed date, the earliest practical response and who will make the call. Update both calendars when a change is confirmed. This prevents one person from changing a moving booking while another still expects the earlier possession date.

Frequently asked questions
Does a CPF refund become cash for my next deposit?
Check which account receives the refund and which funds may be used for the next purchase. Record upfront cash separately from CPF amounts and confirm the rules that apply to the next property and loan.
Can I rely on both completions happening on the same day?
Confirm the arrangement and eligibility with the parties handling both transactions. If one timeline shifts, revisit the purchase funding and where you can live in the interim.
What if I have only an estimated sale price?
Run the worksheet with more than one price and check the net proceeds and payment timing in each case. Use verified transaction figures as they become available.
