By the time completion arrives, most of the real work, the HFE letter, the OTP, the resale application, is already done. Completion is where the money and the keys actually move.
The full timeline in brief
A typical HDB resale journey runs: HFE letter (week 0 to 4), property search and OTP (week 4 to 6), OTP exercise within 21 days, resale application submitted independently by buyer and seller on the HDB Flat Portal (week 6 to 8), HDB inspection (week 8 to 10), HDB approval in principle (week 10 to 14), and completion with key collection around week 12 to 16. Actual duration varies with HDB's processing load and how quickly both parties respond.
What happens at the appointment itself
At completion, HDB finalises the transfer: your outstanding loan amount, CPF refund with accrued interest owed by the seller, any resale levy you owe as the buyer, and the balance purchase price are all settled. The seller's existing HDB mortgage or bank mortgage is discharged, ownership is registered in your name, and keys are handed over once HDB confirms everything has cleared.
What can delay completion
The most common causes are a CPF shortfall discovered late, rather than confirmed early, slow return of loan documents to the bank or HDB, or an unresolved query from HDB's inspection of the flat's condition against resale requirements. None of these are unusual, but all of them are avoidable with early confirmation of your funding position.
After the keys
Once you have collected the keys, you are subject to the standard conditions after buying a resale flat, including the flat's Minimum Occupation Period before you can sell or sublet the whole unit, and any resale levy repayment obligations if applicable to your profile.
Frequently asked questions
How long before I get my keys after the OTP is exercised?
HDB's indicative timeline runs to completion and key collection around week 12 to 16 counting from the start of the HFE application, or roughly 6 to 10 weeks after the OTP is exercised, though this varies with HDB's processing load.
What outstanding amounts get settled at completion?
The seller's outstanding HDB or bank loan, the seller's CPF refund with accrued interest, any resale levy owed by the buyer, and the balance purchase price are all settled at the completion appointment before keys are handed over.
Do I need a lawyer for an HDB resale completion?
No. Unlike private property, HDB handles the legal transfer of a resale flat directly through the HDB Flat Portal and completion appointment, there is no conveyancing solicitor equivalent required.
