How long does it take for a transaction to appear on official records after the OTP is exercised, in terms of number of days to completion of sale and record update?

After the Option to Purchase (OTP) is exercised for an HDB or private property in Singapore, the sale typically completes in about 8 to 12 weeks. The completed transaction will appear on official records—such as HDB or URA's published transaction data—about 1 to 3 months after legal completion of the sale.

Timeline breakdown:
- Once the OTP is exercised, both buyer and seller submit the resale application (for HDB), or proceed to sign the Sale and Purchase Agreement (for private property).
- For HDB flats, the transaction generally takes about 8 weeks from HDB’s acceptance of the resale application to legal completion and key collection.
- For private properties, the completion is usually set between 8 to 12 weeks from the date the OTP is exercised, depending on the agreement.
- After legal completion, the transaction is lodged with the authorities. The sale record typically appears on public records such as EdgeProp Singapore’s transaction history within 1 to 3 months after legal completion.

In summary: It takes about 2.5 to 4 months from OTP exercise for a transaction to complete and appear on official transaction records. This includes the period for legal completion and the usual administrative time for record publication.
