🧭 HOW TO USE THIS TOOL

Two tabs: 🏠 HDB Sale for a straightforward HDB resale timeline, or 🔄 HDB Sale + Condo Buy for a coordinated two-track plan when the client is selling their HDB to fund a condo purchase. Enter the OTP grant date first — the exercise deadline, submission window and completion dates all cascade from it. Everything updates live as you drag sliders or change dates. Scroll down for the visual timeline, the combined side-by-side view of both tracks, and the full dated breakdown you can print or share with the client.

📅 THE HDB OTP CLOCK

Day 0 = the date the HDB OTP is granted. The buyer has 21 calendar days to exercise — deadline is 4pm on Day 21. Leaving the exercise date blank models the worst case (full 21 days used); enter the actual exercise date once known. After exercise, the resale application must be submitted within the window stated on OTP Page 4 (the submission-days slider) — HDB then takes roughly 28 working days to process, and completion follows about 8 weeks after acceptance.

🚨 ABSD SEQUENCING — THE COORDINATED TRACK

In the HDB Sale + Condo Buy tab, the condo OTP must be exercised AFTER the HDB buyer exercises their OTP on the HDB flat — that is what keeps the condo a first property at 0% ABSD. Exercise the condo any earlier (same day or before) and the full ABSD rate applies immediately, payable in cash within 14 days of the condo exercise (CPF can only reimburse afterwards). The tool flags this clearly and will not let the sequencing go unnoticed — always double-check the client's actual exercise dates against this rule before they sign anything.

💰 CPF REFUND & CASH TIMING

CPF refund and cash proceeds are only released at completion, not at exercise — the loan is redeemed and CPF refund initiated the same day ownership transfers. If the client is relying on HDB sale proceeds to fund the condo down payment, the completion date (not the exercise date) is the earliest that money is actually available.
