Three different money timelines
Your expected sale price is not your available purchase cash. Outstanding loans, sale fees, potential duties and CPF refunds sit between those numbers. Even an accurate net-proceeds estimate does not establish the date cash will be available. Start with a solicitor-reviewed sale-and-purchase calendar.
Money in CPF follows its own refund and usage rules. Do not put a CPF refund into the cash column or assume that a returned amount will be immediately available for the next purchase. Ask CPF and your solicitor which funds can be used, and when. The sell-before-buying tool deliberately keeps these categories separate.

Sell first: more visibility, another move
Selling first can make the price and completion date of your existing home clearer before a new commitment. The trade-off may be temporary accommodation, storage and more than one move. Obtain actual quotations for those costs and decide whether a short-term arrangement can meet your family’s needs.
Check the obligations that apply to your existing HDB flat before entering a new purchase. This guide does not establish your eligibility to retain, sell or acquire a property. Household circumstances and the relevant HDB conditions need an individual review. Do not rely on a generic upgrader timeline as permission to proceed.

Buy first: overlap needs its own funding
Buying before selling can align the search with the next home, but creates exposure to sale timing and price. Ask the lender how existing housing loans change assessment and loan-to-value limits. Obtain the actual bridging terms, fees and redemption conditions rather than assuming a bridge will be available.
For ABSD, use the ownership profile applicable at acquisition. IRAS sets conditions for any remission or refund. An intended sale is not the same as a completed qualifying disposal. Keep the full potential duty and timing burden in the plan until a professional confirms the exact treatment.

Stress the sequence
Run a conservative sale-price scenario, a delayed sale scenario and a higher-rate scenario. If one missed completion date leaves you unable to pay the next instalment, the plan needs more buffer or a different sequence. A comfortable total budget can still fail because the funds arrive in the wrong month.
Bring the same timeline to your lender and solicitor. Ask them to identify dependencies, including any release of cash, CPF processing, loan disbursement and vacant-possession arrangements. Discuss a shortlist only after those dependencies are understood.
- Check the existing flat’s disposal and occupation conditions.
- Obtain current loan redemption and CPF refund estimates.
- Budget temporary housing, moving and bridging separately.
- Model ABSD without assuming a future refund.
- Document contingencies for a delayed or lower sale.
