One Chuan Grove Payment Scheme: Understanding the Cash-Flow Timeline

The main stages in plain terms

1. Booking. You pay a booking fee to secure the unit and receive an option to purchase. For One Chuan Grove, booking day is 27 February 2027 according to the ERA project highlights.
2. Exercising the option. Within the stated period you sign the sale and purchase agreement and pay the next portion. Stamp duty is generally due around this point, which is why the stamp duty calculator is worth running early.
3. Construction milestones. Further payments fall due as the building reaches defined stages, such as completion of foundations, the reinforced concrete framework, walls, ceilings and so on.
4. Temporary Occupation Permit (TOP). A payment is due when TOP is issued and you collect the keys.
5. Certificate of Statutory Completion. The final payments fall due at statutory completion, with a portion held for a defined period.

Why staged payments matter for budgeting

Under the progressive scheme, your loan is drawn down gradually. Interest is charged only on the amount disbursed, so monthly instalments start small and rise as construction advances. For One Chuan Grove, completion is estimated for end 2030, but the TOP date has not been announced, so the exact timing of later stages is not yet known.

From an analyst's point of view, the key variables are:

• Upfront cash and CPF needed in the first few months.
• The pace of construction, which determines when instalments rise.
• Interest rate changes over a multi-year construction period.
• Your other housing costs, such as rent or an existing mortgage, during the build.

Alternative schemes

Some developers offer variations, such as deferred payment schemes, which shift more of the price to later stages. These may come with a different price. Whether One Chuan Grove will offer any alternative scheme has not been announced. If one is offered, compare total cost and not only the timing of payments.

Modelling your own scenario

To build a realistic cash-flow model, combine three tools on this site. Start with the mortgage calculator to estimate your loan size and indicative instalment. Then use the progressive payment calculator to see how the loan draws down across construction stages. Finally, add the stamp duty estimate as an upfront cash outflow. With completion estimated for end 2030 and TOP still to be announced, try two or three construction timelines around that estimate to see how sensitive your monthly commitments are to the pace of building.
