Before the Option is granted: the sellers must have registered an Intent to Sell for more than 7 days, and the buyers need a valid HDB Flat Eligibility (HFE) letter. The Option Fee is $1 to $1,000; with the Option Exercise Fee the total cannot exceed $5,000.

A planning estimate from HDB's published timeline. HDB's letters and My Flat Dashboard give the actual dates.

How The Dates Are Worked Out

Everything counts from the Option Date. The buyers have 21 calendar days, weekends and public holidays included, to exercise the Option, and it lapses at 4pm on the last day. HDB's own example: an Option granted on 1 April expires on 22 April at 4pm. Buyers using CPF or a loan must submit a Request for Value by the next working day after the Option Date.

After the Option is exercised, buyer and seller each submit their part of the resale application by the date they agreed, and within 7 calendar days of each other. HDB then accepts a complete application within 28 working days. Acceptance starts an 8-week clock: documents are ready to endorse after about 3 weeks, approval follows 2 weeks after endorsement and payment, and completion is about 8 weeks from acceptance.

Because several of those periods are "within" or "about", the table gives an earliest and a latest date. As soon as HDB's acceptance arrives, enter that date and the later rows tighten to a single estimate.

Assumptions And Limits

Periods are HDB's published ones: a 21-day Option Period ending at 4pm, the second party submitting within 7 calendar days of the first, acceptance within 28 working days of a complete application, documents ready about 3 weeks after acceptance, and completion about 8 weeks after acceptance.
Where HDB gives "within" or "about", the table shows a range. The earliest column assumes the second party submits the same day and HDB accepts at once; the latest assumes every period is used in full. Real cases fall in between, and an incomplete application takes longer.
Working days leave out Saturdays, Sundays and the gazetted public holidays for 2026 and 2027. Holidays for later years are not published yet, so dates beyond 2027 may be a day or two early.
The number of days between exercising the Option and submitting the resale application is agreed by buyer and seller and written in the Option. HDB does not fix it, so you enter it.
HDB sets the actual completion appointment. Once you have HDB's acceptance date, enter it to replace the estimated range. Buyer and seller can agree in writing to a later completion date.
